The first is through learning to avoid it. Bed bugs are growing in numbers. Gradually throughout the united states small pockets of bed bugs have built up a resistance to pyrethroid insecticides that are commonly used to eliminate bed bugs due to their low cost and fast acting nature. Relying on chemicals no longer does the trick experts say.

Using it in combination with other pesticides improves its effectiveness but only to a point. Pyrethrum not to be confused with pyrethroid is an insecticide derived from dried flower heads specifically chrysanthemum cinerariifolium. There are two ways that this occurs. It is a synthetic compound which means it is artificially manufactured to imitate the functioning of naturally occurring compounds.

In fact the number of reported bed bug incidents has grown by 500 in the last decade alone. Despite being one of the most effective bed bug pesticides permethrin isn t perfect. This phenomenon can be the result of many factors one of which being their growing resistance to pesticides like permethrin. Bed bugs are highly resistant to permethrin and it no longer has any lasting effect on their population when it is used alone.

The second is through developing physical resistance. There is growing evidence that bed bugs are becoming immune to it. By definition permethrin is a chemical compound of the pyrethroid family commonly used in the extermination of household pests and parasites including bed bugs mites and lice. Bed bugs are developing resistance to two commonly used insecticides bifenthrin and chlorfenapyr according to a new study.
