49. Control Household Pests With Less Toxic Alternatives
|
|
A variety of strategies avoid the use of synthetic pesticides in
the home. Here are some nonchemical control options.
Eliminate entry points to the house. Place screening over openings,
as well as on air vents and ducts. Use caulk to close cracks and
crevices, especially around water pipes and windows. Seal or repair
openings on the exterior of the house. Also, screen attic vents.
Inspect plants and food products for infestations before you bring
them into your house.

Eliminate
the insects’ sources of food, water, and shelter. Dispose of
food waste in sealed plastic bags, or in containers that have snap-on
lids. Empty garbage on a weekly basis or more often. Don’t allow
food to remain in the garbage disposal overnight. Store bulk foods
in sealed containers. Keep pantry and cabinet shelves, toasters, and
couch cushions “crumb-free.” |
|
Remove
pet food and water bowls from the floor at night, especially if cockroaches
are problem. Discard overripe fruits, onions, and potatoes to control
fruit flies and fungus beetles. Also, remove bird nests from your
house. Vacuum regularly and thoroughly, or steam-clean carpets and
upholstered furniture, to reduce some pest populations. |
|
Eliminate
or disrupt the habitat where a pest resides. Store wood away from
the house because it can harbor termites and other pests. Remove debris
and fallen leaves near foundations and limbs that touch the house.
Use a dehumidifier, especially in basements. In a dry environment,
problems with sowbugs, centipedes, silverfish, firebrats, and dust
mites are reduced. |
|
Certain
old-fashioned methods still work. To eliminate visible or less mobile
insects, there’s the old reliable rolled-up magazine, fly swatter,
or the sole of your shoe. The vacuum cleaner is the most appropriate
tool for eliminating boxelder bugs, black vine weevils, and elm leaf
beetles that have moved indoors. |

Insecticidal dusts tend to be less hazardous to humans than most synthetic
pesticides. They do not vaporize in the air and pose little risk of
injury due to skin contact. Even so, they can irritate mucous membranes
and the respiratory tract, so use goggles and a dust mask. Three of
the most common insecticidal dusts are silica aerogel, diatomaceous
earth, and boric acid. |
|
Traps
use sticky substances or funnel-shaped openings to capture insects
and rodents; they catch only the pests that wander into or onto the
trap. With bait stations, on the other hand, the insect collects a
poisoned bait, takes it back to the nest, and shares it with the rest
of the colony. As a result, baits often do a better job than traps
in controlling a large pest population. |
