Pest Control Tips

Every home-dweller has to eventually contend with pests such as insects, raccoons, and rodents. But don't fret: There are time-proven ways to deter and eradicate these little beasts. We've collected some here:
Insects
  • Keep ants away from your home with a concoction of borax and sugar. Mix 1 cup sugar and 1 cup borax in a quart jar. Punch holes in the jar's lid, and sprinkle the mixture outdoors around the foundation of your home and around the baseboards inside your house. The ants are attracted by the sugar and poisoned by the borax.
  • If you have cockroaches, sprinkle borax powder in the kitchen and bathroom cabinets. Avoid sprinkling where children and pets could be affected.
  • If there's a hornet, wasp, bee or other flying insect in your house and you have no insect spray, kill it with hair spray.
  • If your home becomes infested with fleas, vacuum rugs thoroughly before spraying, and throw the dust bag out at once.
  • Change the water in a birdbath every 3 days to help reduce the mosquito population.
  • The presence of carpenter ants indicates another problem. Because they're fond of damp wood, you should check your pipes, roof and windowsills for water leaks.
  • Centipedes prey on other bugs, so the presence of centipedes in your house may indicate the presence of other insects as well.
  • You can distinguish termite damage from other insect damage by examining any holes you find in wood. Termites usually eat only the soft part of wood, leaving the annual rings intact.
  • If you live in a multiunit building, any pest control measures you take individually will be ineffective in the long run simply because insects can travel form one apartment to another. To eliminate bugs completely, the entire building should be treated at one time.
Raccoons and Rodents
  • Raw bacon or peanut butter makes good bait for a mousetrap. Make sure a mouse will have to tug the trap to remove the bait. If you're using peanut butter, dab some on the triggering device and let it harden before setting the trap. If bacon is your bait, tie it around the triggering device.
  • If a raccoon sets up housekeeping in your attic or chimney, chemical repellants -- such as oil of mustard -- are temporarily effective. (The smell may bother you as much as it does the raccoon.) Your best bet is to let the animal leave, and then cover its entrance hole with wire mesh so that it cannot return.
  • To keep rodents out of your house, seal every opening they could squeeze through. Some need less than 1/4 inch of space. Put poison in deep cracks or holes, and stuff them with steel wool or scouring pads pushed in with a screwdriver. Close the spaces with spackling compound mixed with steel wool fragments.

Winter Pests and Bugs

There's no doubt that summer is prime pest season. Insects are abundant; flies and mosquitoes buzz freely in through opening doors and windows; and wildlife, including rats and mice, actively roam around grassy lawns and open fields.
But, as too many too often learn, such pests don't go completely inactive in the winter. In fact, when it is cold and wet or snowy outside, pests are even more likely to seek the warmth and shelter of the indoors. Some of most common winter pests and guidance for control include:  

  1. Winged Carpenter Ants - Flying ants in the home are rarely a good sign, and this is particularly true if they are seen indoors during the winter. Finding a winged ant or two indoors during the summer does not necessarily mean there is a problem, but if winged ants are seen in the home during the winter months, there is a strong likelihood that there is a carpenter ant nest within the structure.

  1. Cluster Fly - Homeowners generally expect to have to swat a fly or two in the house during the summer months. With family members constantly filing in and out; doors being propped while groceries are carried in; windows opened to screens that need mending, it is generally more likely that a fly will get in than that all will be kept out.
 
  1. Mice - A wily, curious creature, the house mouse is the most common of home-invading mice. Cute, perhaps, in a cage in the pet store, but not so cute when it decides to make your house its home.
 
  1. Rats - Two species of rodents are most common in the U.S.: the Norway rat and the roof rat. Along with the common house mouse, both rats are believed to have been brought to the U.S. aboard ships bound for the New World in the 17th and 18th centuries.
 
  1. Bed bugs - For decades, the saying “Sleep tight, don’t let the bed bugs bite” was a fairly meaningless lights-out phrase for kids in the U.S. But within the last few years, bed bugs have reappeared, causing sleepless nights for homeowners and hotel owners alike.
 
  1. Fruit Fly - The fruit fly is one of the most common, and one of the smallest flies found in the home. It is often unknowingly brought into the home on fresh fruits and vegetables
 
  1. Moth Fly - Moth flies (Psychoda sp.) are a common small fly generally seen buzzing around drains - thus its common name of drain fly. Though it causes no real damage, its high numbers can cause it to become a nuisance pest in or around the home.
 
  1. Spiders - There are more than 35,000 known spider species in the world, with only about a tenth (3,500) of those appearing in the U.S. and often only one tenth (350) of those in any single region. In general, spiders are beneficial creatures, preying and feeding on flies, crickets, mites, and other household and yard pests. Most are completely harmless to humans. But when they get into your home, they can definitely be a nuisance.
 
  1. Overwintering Insects - Any discussion of insects over the winter is likely to elicit the term "overwintering." While its meaning can be as simple as indicating how an insect (or other animal or plant) spends its time over the winter, it more frequently is used to refer to a sort of hibernation undertaken by insects in order to survive the cold temperatures.
 
  1. Firewood Pests - A wood-burning stove or fireplace can bring a great deal of warmth, comfort and pleasing aesthetics into a home. However the firewood that is brought into the home for that fire can also bring with it a number of household pests.
 

Prevent Home Invasion

 

  As described in Tips for Control of Firewood Insects (described above), you can prevent home invasion of pests, and there are methods to control them if they do get in: Rodent Control - The best method of rodent control is prevention through sanitation and exclusion. But these clever creatures can enter a home or building through spaces much smaller than the seeming roundness of their bodies and they are constantly seeking food, water, and shelter. Thus, it is important to keep an eye out for signs of mice and rats and understand control methods. Pest Proof Your Home - If you are like almost half the households questioned in a University of Kentucky survey, a single cockroach in your home would cause you to pull out a can of bug spray or call a pest control professional. Get Rid of Ants - To solve an ant problem, you need to first eliminate the ones you don’t see in order to get rid of the ones you do. Ants are very social insects with very strict hierarchies.  

Calling a Professional

 

  Sometimes it is just better to call on a professional. When that is the case, there are: Top 12 Considerations in Hiring a Pest Control Professional. Sometimes it is better to hire a pest control professional than to try to do it yourself. This is particularly true if the pest problem is ongoing, if the infestation has become large, or if the products needed for control are only authorized for use by certified professionals.

Bed Bug Control Techniques

Bed bugs, or cimicidae, are small parasitic insects. The term usually refers to species that prefer to feed on human blood.

Early detection and treatment are critical to successful control. According to a survey, the most commonly infested places are the mattress (98.2%), boxspring (93.6%), as well as nearby carpets and baseboards (94.1%). In fact, bed bugs thrive in areas where there is an adequate supply of available hosts, and plenty of cracks and harborages within 1.5 metres (4.9 ft) of the host.
Because treatments are required in sleeping areas and other sensitive locations, methods other than chemical pesticides are in demand. Treatments can be costly, laborious, time consuming, repetitive, may entail health risks, and cause embarrassment to the person affected.

Public health

Bed bug infestations spread easily in connecting units and have negative effects on psychological well-being and housing markets. In response, many areas have specific laws about responsibilities upon discovering a bed bug infestation, particularly in hotels and multi-family housing units, because an unprofessional level of response can have the effect of prolonging the invisible part of the infestation and spreading it to nearby units. Common laws include responsibilities such as the following: Lessors must educate all lessees about bedbugs, lessee must immediately notify lessor in writing upon discovery of infestation, lessor must not intentionally lease infested unit, lessee must not intentionally introduce infested items, lessor must eradicate the infestation immediately every time it occurs at a professional level including all connecting units, and lessee must cooperate in the eradication process.
An example of how epidemic bed bug infestation can become in densely populated areas is the Bed Bug Registry. Mapped bed bug reports graphically illustrate how difficult it can be to eliminate bed bugs where many people live in adjacent units like in New York City, Los Angeles, and San Francisco.

Pesticides

Though commonly used, the pesticide approach often requires multiple visits and may not always be effective due to pesticide resistance and dispersal of the bed bugs. According to a 2005 survey, only 6.1% of companies claim to be able to eliminate bed bugs in a single visit, while 62.6% claim to be able to control a problem in 2–3 visits. Insecticide application may cause dispersal of bed bugs to neighbouring areas of a structure, spreading the infestation. Furthermore, the problem of insecticide resistance in bed bug populations increases their opportunity to spread. Studies of bed bug populations across the United States indicate that resistance to pyrethroid insecticides, which are used in the majority of bed bugs cases, is widespread. Exterminators often require individuals to dispose of furniture and other infested materials. It is advisable to break or mark these infested items to prevent their being unintentionally recycled and furthering the spread of bed bugs.

Effectiveness

The well-established resistance of bed bugs to DDT and pyrethroids has created a need for different and newer chemical approaches to the extermination of bed bugs. In 2008 a study was conducted on bed bug resistance to a variety of both old and new insecticides, with the following results, listed in order from most- to least-effective: λ-cyhalothrin, bifenthrin, carbaryl, imidacloprid, fipronil, permethrin, diazinon, spinosyn, dichlorvos, chlorfenapyr,and DDT.[4] Note that the first of these, λ-cyhalothrin, is itself a pyrethroid-based insecticide— in the past, however, it has been used principally for the treatment of cotton crops and so bed bugs have not developed a genetic resistance to it.

Disadvantages

Non-residue methods of mattress treatment are desired in place of contaminating mattresses with insecticides. Furthermore, other methods such as vacuuming must often be used in conjunction with pesticides to fully eradicate bed bugs. Spraying the mattress with insecticide is undesirable as the room must be suitably ventilated, sufficient time must be given after application before the mattress can be used again and there is a risk of the user having an allergic reaction to the chemicals, not to mention other possible health risks including cancer and acute neurotoxicity.
Concerns over the possible health effects of pesticides on people and pets, as well as the dispersal of bed bugs to neighbouring dwellings due to repellent effects of insecticides, make the practice of chemically treating the mattresses problematic.

Resistance

Bed bugs are developing resistance to various pesticides including DDT and organophosphates. Some populations have developed a resistance to pyrethroid insecticides. Although now often ineffective, the resistance to pyrethroid allows for new chemicals that work in different ways to be investigated, so chemical management can continue to be one part in the resolving of bed bug infestations. There is growing interest in both synthetic pyrethroid and the pyrrole insecticide, chlorfenapyr. Insect growth regulators, such as hydroprene (Gentrol), are also sometimes used.
Populations in Arkansas have been found to be highly resistant to DDT, with an LD50 of more than 100,000 ppm. DDT was seen to make bed bugs more active in studies conducted in Africa.
Bed bug pesticide-resistance appears to be increasing dramatically. Bed bug populations sampled across the U.S. showed a tolerance for pyrethroids several thousands of times greater than laboratory bed bugs.  New York City bed bugs have been found to be 264 times more resistant to deltamethrin than Florida bed bugs due to mutations and evolution.
A population genetics study of bed bugs in the United States, Canada, and Australia using a mitochondrial DNA marker found high levels of genetic variation. This suggests the studied bed bug populations did not undergo a genetic bottleneck as one would expect from insecticide control during the 1940s and 1950s, but instead, that populations may have been maintained on other hosts such as birds and bats. In contrast to the high amount of genetic variation observed with the mitochondrial DNA marker, no genetic variation in a nuclear RNA marker was observed. This suggests increased gene flow of previously isolated bed bug populations, and given the absence of barriers to gene flow, the spread of insecticide resistance may be rapid.

Physical isolation

Isolation of humans is attempted with numerous devices and methods including zippered bed bug-proof mattress covers, bed-leg moat devices, and other barriers. However, even with isolated beds, bed bug infestations persist if the bed itself is not free of bed bugs, or if it is re-infested, which could happen quite easily.

Inorganic materials

Inorganic materials such as diatomaceous earth may be used in conjunction with other methods to manage a bed bug infestation, provided they are used in a dry environment. Upon contact with such dust-like materials, the insect's waxy outer layer of their exoskeletons is disrupted, which causes them to dehydrate.

Although occasionally applied as a safe indoor pesticide treatment for other insects, boric acid is ineffectual against bed bugs because bed bugs do not groom.

Organic materials

 

Bean leaves

A traditional Balkan method of trapping bed bugs is to spread bean leaves in infested areas. The trichomes (microscopic hooked hairs) on the leaves trap the bugs by piercing the tarsi joints of the bed bug's arthropod legs. As a bug struggles to get free, it impales itself further on the bean leaf's trichomes. The bed bugs and leaves then can be collected and destroyed. Researchers are examining ways to reproduce this capability with artificial materials.

Essential oils

Many claims have been made about essential oils killing bed bugs. However, they are unproven. The FTC is now filing a suit against companies making these claims.

Contaminated belongings

Disposal of items from the contaminated area can reduce the population of bed bugs and unhatched eggs. Removal of items such as mattresses, box springs, couches etc. is costly and usually insufficient to eradicate infestation because of eggs and adults hiding in surrounding areas. If the entire infestation is not eliminated prior to bringing new or cleaned personal and household items back into a home, these items will likely become infested and require additional treatment. Treating clothing, shoes, linens, and other household items within the affected environment is difficult and frequently ineffective because of the difficulty of keeping cleaned items quarantined from infestation. Many bed bug exterminating specialists recommend removing personal and household items from the infested structure. Many metropolitan areas offer more effective treatments such as high-heat dryers and dry cleaning with PERC with the added benefit of the treated items remaining stored until the affected home's bed bug infestation is eradicated

The improper disposal of infested furniture also facilitates the spread of bed bugs. Marking the discarded items as infested can help prevent infesting new areas. Items may also be sealed in plastic and stored until all eggs hatch and all larvae and adults have died. Bed bugs can go without feeding for 20 to 400 days, depending on temperature and humidity. Older stages of nymphs can survive longer without feeding than younger ones, and adults have survived without food for more than 400 days in the laboratory at low temperatures. Adults may live up to one year or more, and there can be up to four successive generations per year.

Vacuuming

Vacuuming helps with reducing bed bug infestations, but does not eliminate bed bugs hidden inside of materials. Also, unless the contents of the vacuum are emptied immediately after each use, bedbugs may crawl out through the vacuum's hoses and re-establish themselves.

Heat treatment

Steam

Steam treatment can effectively kill all stages of bed bugs. To be effective, steam treatment must reach 150–170 degrees for a sustained period. Unfortunately, bed bugs hide in a diversity of places, making steam treatment very tedious, labour-intensive and time consuming. There is also the risk of the steam not penetrating materials enough to kill hidden bed bugs. The steam may also damage materials such as varnished wood, or cause mold from the moisture left behind. Effective treatment requires repeated and very thorough steaming of the mattress, box spring, bed frame, bed covers, pillows, not to mention other materials and objects within the infested room, such as carpets and curtains.

Clothes dryers

Clothes dryers can be used for killing bed bugs in clothing and blankets. Infested clothes and bedding is first washed in hot water with laundry detergent then placed in the dryer for at least 20 minutes at high heat. However, this does not eliminate bed bugs in the mattress, bed frame and surrounding environment. Sterilized fabrics from the dryer are thus easily re-infested. Continually treating materials in this fashion is labour-intensive, and in itself does not eliminate the infestation.

Hot boxes

Placing belongings in a hot box, a device that provides sustained heat at temperatures that kills bedbugs, larvae, and eggs, but that does not damage clothing, is an option. Pest control companies often rent the devices at nominal cost and it may make sense for frequent travelers to invest in one.

Building heat treatment

This method of bed bug control involves raising room temperatures to or above the killing temperature for bed bugs, which is around 45 °C (113 °F). Heat treatments are generally carried out by professionals, and may be performed in a single area or an entire building. Heat treatment is generally considered to be the best method of eradication because it is capable of destroying an entire infestation with a single treatment.
For safety reasons, it is important that HEPA air filtration is used by your professional during any heat treatment to capture particulate and biological matter that may be aerosolized during the heating process.

Freezing

Many claims exist about the effectiveness of freezing Bedbugs. They vary from freezing works, it only works in extremely low temperatures, to it doesn't work at all. The theory is, in areas where outdoor temperatures drop below freezing, mattresses, couches, and other furniture can be placed outside for 24 hours allowing the bedbugs to freeze.

Fungus

Preliminary research has shown the fungus Beauveria bassiana, which has been used for years as an outdoor organic pesticide, is also highly effective at eliminating bed bugs exposed to cotton fabric sprayed with fungus spores. It is also effective against bed bug colonies due to the spores carried by infected bugs back to their harborages. Unlike typical insecticides, exposure to the fungus does not kill instantly, but all subjects died within 5 days of exposure. Some people, especially those with compromised immune systems, may react negatively to the concentrated presence of the fungus directly following an application.



Drugs

Early research shows that the common drug taken to get rid of parasitic worms, Ivermectin (Stromectol), also kills bed bugs when taken by humans at normal doses. The drug enters the human bloodstream and if the bedbugs bite during that time, the bedbug will die in a few days. Stromectol is also effective against mosquitoes, which can be useful controlling malaria.

Pest Control for Bed Bugs, a Professional Job!

Act quickly to avoid spread of bed bugs

MARILYN LINCOLN, Special to QMI Agency
It has been three months since I discovered bed bugs have invaded my condo townhouse. I have spent $700 on a pesticide company and still have the problem. I am a spotless housekeeper so this cannot be my fault. I am afraid to go to sleep at night because of the bites. My life has become a nightmare. My family and friends won't visit. When I first discovered the bed bugs I thought they came from one of the adjoining townhouses on either side of me. However, my neighbors had no signs of bed bugs but became very alarmed regarding my situation. The condo management has informed me that is my duty to get rid of these bed bugs before they spread. What more can I do? Please help. I am at the end of my rope.
When parents tucked their children into bed years ago the old saying was: "Sleep tight and don't let the bed bugs bite." Once thought to be eradicated after the Second World War, bed bugs are making a huge comeback.
Pesticides such as DDT were once used to control bed bugs, but concerns about health and the environment led to many of these pesticides being banned.
Bed bugs can originate from various sources. Some common places are infested furniture in hotels, motels and carried around in the luggage of travelers. They have made there way into libraries, hospitals and movie theatres.
No matter how clean you are, if someone brings bed bugs into your home they will spread quickly.
Bed bugs feed on blood not on trash. They bite exposed skin and leave behind small, red, itchy welts. They can cause serious emotional problems for people who can't get rid of them.
Bed bugs are big enough to be seen. They hide under mattresses and in the seams, in and around bed frames, along any cracks or peeling paint in the wall, picture frames, wooden furniture, behind baseboards, in carpets, behind wallpaper.
Once you discover bed bugs, time is of the essence before a huge infestation occurs. READ MORE about Bed Bug Pest Control
