Residential Mosquito Control Safety
You can have confidence that our mosquito control sprays
offer many benefits, but safety is #1.
Pyrethrin
Pyrethrum is a botanical insecticide produced primarily from the flowers of Tanacetum
cinerariaefolium, which is a species of the chrysanthemum plant family. It is found mainly
in tiny oil-containing glands on the surface of the seed case in the tightly packed flower
head and is the plant's own insecticide that has evolved to keep insects away. Pyrethrum is
made up of six complex chemical esters known as pyrethrins which work in combination to
repel and kill insects.
Pyrethrin has been used effectively to control insects for decades. It decomposes
rapidly in the environment, making it an excellent choice for controlling pests.
Pyrethrin has been extensively studied from a toxicology
viewpoint. It is low in acute toxicity to humans and other vertebrate animals, is
non-carcinogenic and causes no adverse reproductive affects.
Pyrethrin is commonly
used as a post harvest treatment for fruits and vegetables especially during shipment
and is popular as a non-residual household insecticide spray.

Permethrin
Permethrin is a broad spectrum synthetic pyrethroid insecticide. Permethrin has been around
since the 1970's and is widely used today in public health, home pest control, forestry, agriculture
and head lice control. Some examples of use include
In the US over 100 million applications of permethrin are made each year
in homes and over 18 million applications are made in yards and gardens.
Permethrin, like all synthetic pyrethroids, kills insects by strongly exciting
their nervous systems.

PBO (Piperynl Butoxide)
PBO (Piperonyl Butioxide) is an emulsifiable synergist for use in combination
with insecticides, especially synthetic pyrethroids, as a tank mix to overcome
resistance that pests develop with constant use of insecticides.
PBO is a unique tank additive that restores activity against resistant strains of
pests. It acts by inhibiting naturally occurring enzymes that would otherwise
degrade the insecticide molecule.
PBO breaks through the insect's defense and its synergistic activity makes the
insecticide more powerful and effective. With the high cost of insecticides, PBO
effectively reduces the cost per gallon of spray solution by allowing the applicator
to use less active ingredient to obtain the mortality rate desired.
Insects are amazingly adaptable, and possess an enzyme system called the
mixed-function oxidases (MFO's) that give them the ability to de-toxify and
become resistant to many insecticides, especially synthetic pyrethroids.
Continual application of pesticides start the build-up of resistance and thus the
efficacy of the spray diminishes. PBO inhibits the action of MFO's and restores
the killing power of the insecticide, which results in less expensive and/or more
effective pest control. Actual results show that PBO either decreased the cost of
pest control since smaller doses are needed, or provided better control of insects
where cases of maximum dosages of pesticides without PBO had failed.
Therefore, PBO will PROLONG the usefulness of insecticides by overcoming
MFO resistance. Improved control means fewer applications of insecticides, thus
providing cost savings as well as environmental benefits.
