After insects have developed resistance against many of the most powerful pesticides, such as DDT, the exterminators were increasingly dependent on two chemicals: chlorfenapyr and bifenthrin. But so far, no one had examined whether the bugs themselves developed defenses against these chemicals, as Ameya D. Gondhalekar, lead author of the study and research assistant at the Department of Urban and Industrial Management of Insectomorphic Pests at Purdue University .
Gondhalekar and his team have exposed Ten different bed bugs collected from different parts of the country to each of the chemicals in a glass vial. After several days, they examined the effectiveness of chemicals in the killing of bugs.
While most of the bugs were removed from the chemicals, three groups continued to thrive after being treated with clorfenapir and five groups continued to kick after being treated with bifenthrin. This means that while some bugs in bed will respond to these chemicals, others will not, and more and more insects are likely to become resistant over time.
“This is just a clear evidence that this approach to pesticides only for bed bug control is not working,” says senior researcher Michael Hansen, Ph.D. “The grip is that if you want to check these bugs, you can not spray them. “
How to Prevent Bedbug Infestation
Prevention and surveillance are the key to preventing bug bug problems. “It’s much easier to control them if they find it soon [when they are few], unlike when they grow to hundreds,” says Gondhalekar.
Look at your home. Insects are hidden in slits and slits like walls, luggage, boxes, and clothing, but as they feed humans during sleep, they are more often found in the beds. If you suspect an infestation or if you live in a apartment building with a bed problem, check your sheets regularly, mattress (also below) and spring stitching for insects. They are flat and oval, with red or brown bodies, about the size of an apple seed. Observe adults, nymphs and eggs, as well as exoskeletons (windings that insects leave when they move) and dark and rusty spots (feces).
Encase the mattress. Enclosing your mattress, pillows, and basin with a protective cover can block insects to reach your favorite hideout.
Be careful when traveling. The hotel and motel rooms are hotbeds for bed bugs. At check-in, they put their luggage in the bathroom, and then inspected the bedding. Keep your bags in a carry case or on a hard surface.
When you come home, quarantine your bags. Decontaminate your luggage and garments by putting your suitcase in a large chest freezer (if you have one) for four days, Gondhalekar suggests, before bringing them home. Hot or cold extreme temperatures kill bed bugs. You can also put your clothes in the dryer in a warm environment for 30 minutes and try to wet your luggage and clothes.
How to Treat a Infestation of a Bed
Minimize its diffusion. First, tell your landlord if you rent a building to check its spread in other units. Remove all infected areas, including carpets and mattresses, and then empty the bag in a plastic bag, seal it and throw it away. If you can not remove the beds from the furniture, discard the items responsibly. To prevent someone else from saving children’s furniture or mattresses, tear, remove padding or spray paint with the words “bed bugs“.
Bring the heat. The heating of infested furniture or the whole apartment at a very high temperature – more than 100 degrees, in most cases – will kill the bugs. If you have a hand held steamer,blast cracks and cranny.
Use an insecticide alternative. Substances such as diatomaceous earth, boric acid, and silica gel kill bed bugs by damaging their outer lining to dry and die. Put these powders in cracks and Cranny around your home (be careful not to ingest or inhale).
Ask for professional help. Not all insect beds respond to insecticides in the same way, so if you have an infestation that you can not control yourself, a professional can help you determine the correct or insecticide treatment for your use.
