Thrip Information Control
Thrips are very small, slender insects that often are barely visible to the
eye. Although small in size, they loom very large as pests of many crops.
Bailey (1936) states that the onion Thrips particularly the larvae, are apt to bite
people. This bite produces a prickling sensation which results in a slight itching
but no swelling. At times these insects invade the home from adjacent fields.
Grass Thrips or "oat bugs" feed on grains and grasses. From there, they
migrate into houses. These insects are sometimes small enough to enter homes through
conventional window screens and bite residents. The bite may cause a mysterious
rash. People have also been bitten by Thrips brought in on blankets hung in the
yard. On occasion, pear Thrips will bite. Thrips occasionally become serious
pest in summer in grassy areas and around swimming pools. Indoors, Thrips can cause a
serious visual nuisance by crawling behind the glass of framed pictures.
Chemical control of Thrips that are biting people around homes or recreation sites is
accomplished by directing the chemical spray at the host plant: flowers, grasses, etc.
as well as the grounds around such infested vegetation. Once Thrips invade
the home or are known to bite humans, all possible Thrip harborage and entry
points should be treated with an approved insecticide. When choosing a
Thrip spray or dust you should make sure that the pest control product is
labeled for use in areas in need of treatment.
Personal protection is available but is only recommended in situations where
working in an infested area results in irritating Thrip bites. DEET can
offer some temporary relief from biting Thrips but should not be relied on for
control of the infestation.
There are several pest control sprays to choose from, each with its advantages
and limitations. Natural
Rx is an all natural insect repellent manufactured by Dr.
T's Nature Products. This bug spray is a ready to use product that can
be used on any type of plant material including fruits, vegetables and
ornamentals. With a broad label you can spray this product on any type of
plant but do not expect a long residual with the spray. Use outdoors only.
Another natural product that can be used on most plants is Pyrethrin-Rotenone Spray.
Rx and Pyrethrin-Rotenone Spray
products satisfy the needs of those who wish to use organic type products or
when plants yielding edible fruits or vegetables need to be sprayed.
When a better product (with better knock-down and longer residual) is needed,
choose a professional pest control product that is labeled for areas infested
with Thrips. Dragnet (Professional strength
Permethrin) and Talstar
are concentrates that are labeled for treating most trees, shrubs, ornamentals
and lawns. Neither of these two products are labeled for fruit or
Dragnet is a multi-purpose insecticide concentrate that contains the highest
concentration of Permethrin insecticide. Use this product for a wide range
of pests found in homes as well as on ornamental plants around the exterior of
buildings. Dragnet has what is called an "indoor broadcast
label" which allows spraying of indoor flooring, carpets and furniture when
treating for fleas, ticks, etc.
Talstar One is
the very best concentrated insecticide available for treating shrubs, trees and
ornamental plants for a wide variety of pests and is excellent for killing
is also an odorless product that requires very small amounts of concentrate to
yield professional results.
