Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests.
Cockroaches will feed on almost anything, including refuse, fecal matter and food for consumption. They also require access to water, and will be generally found in inaccessible harborages, close to water and food. Cockroaches can survive for several months without food, but will not live for more than a few days without water.
Cockroaches are commonly found in buildings and homes because they prefer warm environments close to food and water. Unfortunately, cockroaches can cause allergies and trigger asthma attacks, especially in children. They can also spread nearly 33 different kinds of bacteria.
Recipe to get rid of them:
Take one egg yolk (raw) and put it in about 1.7 oz (50 grams) of powdered boric acid. Stir the mix well. The objective is to obtain thick mix. Produce little balls from this mix. After one hour, the balls ought to be dry, so you can begin putting them in every corner of your home and the locations where you generally see cockroaches like the restroom and the kitchen area.
Traps can be effective in reducing existing roach populations, but they won’t get rid of roaches on the outside trying to break in. To prevent a roach infestation from expanding, use caulk to fill possible entry points, including gaps between walls or tile, small crevices and entry holes.
An important identifying distinction is that the common German cockroach breeds inside and contaminates its living environment while larger cockroaches do not breed inside. The most common larger roaches breed outside and are more of a nuisance than a danger. These larger sized roaches are not known to spread disease. Treatment options are different based on the type of cockroach.
The Oriental cockroach (Blattaorientalis) is the so-called “waterbug” of basements, crawlspaces and garages. It lives in cooler habitats with plenty of moisture – even outdoors around foundations in leaves and mulch where it can survive temperate winters.
Cockroaches must have a source of water. Depending on the temperature and their size, they can live for a month without any food, but no more than a week without water. Find all the water leaks in your house, and fix them. Once their water source(s) have been eliminated, they will be much more interested in eating gel-based baits you set out.
The best defense against cockroaches is a clean kitchen and bathroom. If roaches are a problem in your home or apartment, vacuum well and wash the area with a strong soap. Dispose of the vacuum cleaner bag in a sealed container.
Cockroaches succumb to boric acid when they crawl over treated areas. The tiny particles of powder adhere to the cockroaches’ body, and the material is ingested as the roach preens the powder from its legs and antennae. Some boric acid is also absorbed through the greasy outer covering of the insect’s body.
