There are many companies constantly working on new chemicals for the bed bug epidemic, so there may be new chemicals out since the time this was written |
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.
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.
In general, there are four types chemicals that are used against bed bugs.
Natural pyrethrins. Pyrethrins are made from chrysanthemum flowers, which are grown especially for their insecticidal properties. Pyrethrins are considered to be among the safest insecticides for humans, though they can cause eye, skin and respiratory irritation. Because natural pyrethrins break down fairly quickly, they will put a dent in the bed bug population, but tend not to have the residual effect necessary to kill off an infestation.
Synthetic pyrethrins. These are chemicals with names like deltamethrin and lambda-cyhalothrin. These have longer residual effectiveness and are generally water-based, so they are less likely to damage furniture or wood than their oil-based natural pyrethrin cousins.
Inorganic materials, like diatomaceous earth, silica and boric acid. These will last long, and don?t drive bugs away (which you don?t want ? you want them to take a good, deep dose of the bug killer and die). They kill by mechanical action ? scratching open the bug?s skin so it dehydrates. They are good for cracks and crevices, but have to be used in a low-humidity environment. Can leave a whitish film on surfaces.
Insect growth regulators (IGRs), such as hydroprene. These don?t generally kill the bugs, but instead disrupt their reproductive cycle, so they cannot lay viable eggs.
When an exterminator treats bed bugs, chances are he'll use insecticides to take them down. There are a lot of chcemicals he might use, and it is important that you, as an informed consumer, understand what the options are. This article contains a listing of the common pesticides for bed bug pest control
There is a lot of new product development happening in this space all the time. If you want to know what chemical kills bed bugs, or pesticides to kill bed bugs, you'll just have to bite the bullet and call a pest controller
