Over the years bed bugs have been evolving and adapting to their environment.
Permethrin bed bugs resistance.
Pyrethrum not to be confused with pyrethroid is an insecticide derived from dried flower heads specifically chrysanthemum cinerariifolium.
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.
This phenomenon can be the result of many factors one of which being their growing resistance to pesticides like permethrin.
Relying on chemicals no longer does the trick experts say.
Bed bugs are highly resistant to permethrin and it no longer has any lasting effect on their population when it is used alone.
It is a synthetic compound which means it is artificially manufactured to imitate the functioning of naturally occurring compounds.
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.
There are two ways that this occurs.
Using it in combination with other pesticides improves its effectiveness but only to a point.
There is growing evidence that bed bugs are becoming immune to it.
Bed bugs are developing resistance to two commonly used insecticides bifenthrin and chlorfenapyr according to a new study.
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.
The second is through developing physical resistance.
Bed bugs are growing in numbers.
The first is through learning to avoid it.
