Chemicals That Kill Bed Bugs And Their Eggs
Instantly.
Pyrethrins and Pyrethroids.
Pyrethrins and pyrethroids are the most common
compounds used to control bed bugs and other
indoor pests.
Pyrethrins are botanical insecticides derived
from chrysanthemum flowers.
Pyrethroids are synthetic chemical insecticides
that act like pyrethrins.
Both compounds are lethal to bed bugs and
can flush bed bugs out of their hiding places
and kill them.
However, where resistant bed bug strains exist,
these treatments may cause them to move to
a new hiding place or temporarily flush them
out of existing locations.
Some bed bug populations have become resistant
to pyrethrins and pyrethroids.
Sometimes using a combination product (either
multiple pyrethroid or pyrethrin active ingredients,
or one that combines different chemical classes
into the same product) can improve bed bug
control.
It can also be helpful to switch to an entirely
different chemical class to control resistant
bed bug populations.
Desiccants.
Desiccants work by destroying the waxy, protective
outer coating on a bed bug.
Once this coating is destroyed, the bed bugs
will slowly dehydrate and die.
Desiccants are a valuable tool in bed bug
control.
Because desiccants work through a physical
mode of action, the bed bugs cannot become
resistant to desiccants as they can to pesticides
with other modes of action.
In addition, they have a long-lasting effect
and don't disturb normal bed bug activities.
Examples of desiccants include.
Diatomaceous earth and Boric acid.
When using desiccants to control bed bugs
it is critical to use those that are registered
by the United States Environmental Protection
Agency, EPA and labeled for bed bug control.
Desiccants that are intended for other uses,
such as food-grade or for use in swimming
pools, pose an increased inhalation risk to
people.
Use of desiccants is limited to cracks and
crevices use only to reduce inhalation risk.
Biochemicals.
Cold pressed neem oil is the only biochemical
pesticide registered for use against bed bugs.
Cold pressed neem oil is pressed directly
from seeds of the Neem tree, a tropical evergreen
tree found in Southeast Asia and Africa.
The oil contains various compounds that have
insecticidal and medicinal properties.
It is also used in making products including
shampoos, toothpaste, soaps, and cosmetics.
Performance trials conducted at the approved
label rates show both products control bed
bug adults, nymphs, and eggs.
Pyrroles.
Chlorfenapyr is the only pyrrole pesticide
currently registered for use against bed bugs.
The compound is a pro-insecticide, i.e. the
biological activity depends on its activation
to form another chemical.
The new chemical disrupts certain functions
in the bed bug's cells, causing its death.
Neonicotinoids.
Neonicotinoids are synthetic forms of nicotine
and act on the nicotinic receptors of the
nervous system by causing nerves to fire continually
until they fail.
Because neonicotinoids use this different
mode of action, bed bugs that are resistant
to other pesticides will remain susceptible
to the neonicotinoid.
Insect growth regulators.
Insect growth regulators are chemicals that
mimic juvenile growth hormones in insects.
They work by either altering the production
of chitin (the compound insects use to make
their hard external "shell" or exoskeleton)
or by altering an insect's development into
adulthood.
Some growth regulators force the insect to
develop too rapidly, while others stop development.
