48. Select The Right Household Pesticide |
|
Once you have identified a pest and decided that using a pesticide
is necessary, select an appropriate treatment method. Choices include
residual pesticides, baits, and space sprays. Remember to read the
pesticide label carefully to find out which products can be used
for the treatment you have in mind.
Residual pesticides are sprayed on surfaces and allowed to dry;
they are intended to work against pests for a few days or weeks
after application. They remain toxic to insects and to pets and
humans, so use them with care.
|
|
The
most effective and safest use for residual pesticides is to apply
them in cracks and crevices where ants, roaches, and other insects
hide. Key application sites are the gaps and spaces along baseboards
and behind appliances, where humans and pets are unlikely to contact
the residue. |
|
Certain
residual pesticides can be sprayed along a doorway threshold, around
the foundation, or along windowsills to keep out some crawling insects.
Before using a pesticide as a chemical barrier, however, first determine
whether the places where insects enter can be plugged with caulk or
weatherstripping. This way, you may be able to avoid insecticides. |
|
It is not a good idea to use residual pesticides to spray surfaces
throughout the interior of a house. Most of the pesticides will wind
up on surfaces that the pests will not contact, but humans will. |
|
Rodent
baits can be deadly, so place them only where they are inaccessible
to children and pets. Always place them inside lockable bait boxes,
which can be purchased where baits are sold. Never place a rodent
bait in an open container under the sink. Traps, including those that
do not kill the offending rodent, are alternatives to baits. |
|
Some
labels state that roach and ant baits are safe enough to place on
countertops, but logic suggests this is a poor idea. You will have
much more success if you place baits where the insects enter the room
or emerge from cracks and voids. Good sites for bait containers are
near pipes, corners, and damp areas. |
|
Space
sprays, usually aerosols, are sprayed or otherwise released into the
air to control such pests as flies and mosquitoes. In general, space
sprays are not very effective for the control of most pests. Additionally,
tiny aerosol droplets of the pesticide settle on surfaces throughout
the house—many of them on surfaces where pests are not active. |
