Know Why Bed Bugs Resist Chemicals

Bed bugs are becoming harder to kill. As they grow resistant to insecticides and chemicals used to get rid of them, the bugs become more of a nuisance. Bed bugs exterminators in St. Louis, MO, know that the best treatments combine techniques and use alternatives to chemicals like bifenthrin and chlorfenapyr. Heat, steam, and silica gel are all effective at treating and killing bed bugs when used in conjunction with the right chemicals. But how did the bed bugs become resistant to the insecticides used to treat them?


Genetic Diversity

In biological organisms, genetic diversity helps to protect the species from being wiped out by a single disease or environmental poison. Some individuals of the species are more resistant to certain bacteria or chemicals. It's one reason why people survived the black plague and not everyone dies from the flu or toxic gas exposure. The same thing is true of bed bugs and other pests.


A Full Dose

In movies and books, it is popular to have characters build up a resistance to certain poison. They do this by ingesting or exposing themselves to small amounts of the poison, and their bodies get used to it. It's the reason why drugs and alcohol don't affect habitual users the way they affect long-time users. It's why MRSA is a problem in hospitals where bacteria have grown resistant to antibiotics, and it's true of bed bugs who never received a full dose of chemicals.


Hide and Seek

Bed bugs are good at hiding and finding small places to survive almost any conditions. Unless they have just eaten and are engorged with blood, bed bugs are flat and can fit in the electrical outlet. They crawl between rooms and floors using the electrical system as their conduit. People who use a home treatment and don't call professional help may only treat the infestation they can see. Some of the hiding insects may be exposed in low doses to remnant insecticides and build up a tolerance.


The Best Treatment?

Integrative treatment techniques that combine the use chemicals, heat, steam, and silica gel are the best way to get rid of bed bugs. By combining these and using the chemicals sparingly, the bed bug resistance to insecticides will slow down. Bed bugs exterminators in St. Louis, MO, know that treatment for bed bugs may take more than one visit, and budget constraints may cause some people to shy away from a technique that's more effective and costlier. Spending more money now is better than having to call an exterminator again a month or two down the road.
