Pest control management has many pesticides that are designed to kill bed bugs. These are in the form of dust powder, sprays, aerosol, insect growth inhibitors and insecticides. These products though, have different formulations primarily constitute pyrethroids, neonicotinoids and chlorfenapyrs.
Pyrethroids are chemical compounds found in Chrysanthemum flowers. This compound has toxic properties on insects, including bedbugs. However, it is not found to harm human beings when used in small doses. First-generation pyrethroids contain ingredients such as tetramethrin, bioresmethrin, bifenthrin and permethrin. These showed instability in sunlight, which made the insects survive the effects of products containing first-generation pyrethroids. Cyfluthrin, elamethrin, cypermethrin, fenvalerate are some of the ingredients present in second-generation pyrethroids. These have more stability and ensure high insecticidal efficacy.
How does Pyrethroids kill bed bugs?
The poison present in pyrethroids, affect the nervous system of the bed bug by stripping through the exoskeleton. This paralyzes the organism by disturbing its nerve transmissions. This disruption causes in-coordination and the death of a bed bug. This makes pyrethroids, a natural choice as an essential ingredient for insecticide or pesticide, especially in the fight against bed bugs. Pyrethroids usually are combined with piperonyl butoxide. This retards the insect’s enzymes from eliminating the pyrethroids from its body. This boosts the chances to kill the insect/organism.
Where is this compound used?
Products using pyrethroids are efficient in treating bed bug infestation at residential, commercial and public properties.
Is it effective only on bed bugs?
Since Pyrethroids are used in insecticides, it is highly efficacious to curb the population of other insects such as ants, cockroaches, stinging insects, spiders and ladybugs.
Which formulation of pyrethroids is effective to kill bed bugs?
There are several formulations of pyrethroids available in the market as – concentrates, dust powder, granules, microencapsulates, tablets, sprays and powders that can be mixed in water. Depending on the location of the infestation, a pest-control professional can guide to use the appropriate formulation for treatment.
Neonicotinoids, obtained from nicotine has shown to be effective in curbing a bed bug menace. Interestingly, bed bugs do not show resistance to this compound. This is combined with pyrethroids to treat a bed bug infestation.
Chlorfenapyrs belonging to the pyrrole group is yet another compound that is used to bed bug insecticides. This is non-toxic and is quite ineffective in controlling the bed bugs.
Hydropene is s a chemical that is effective in disturbing the life cycle of the bed bugs. Falling under the insect growth regulator category (IGR), insecticides containing hydropene prevents the growth and reproductive ability of bedbugs. This agent thus, curbs the population of bed bugs by tampering with its development. Since it simply a birth-control ingredient, Hydropene is used in conjunction with other compounds to make the treatment more effective to kill bed bugs.
A comprehensive approach of using all the compounds is a better way to control the bedbugs. Recent years have seen the introduction of insecticides that use a combination of pyrethroids, chlorfenapyrs and neonicotinoids which seem to kill the bedbugs.
