Will cockroach baits spread twice

Secondary transmission of toxic baits

Cockroaches eat the feces of other roaches and they feed on each other. After consuming a lethal dose of a residual bait insecticide known to have delayed toxicant activity, cockroaches return to the harborage where they excrete feces. The insecticide-laden feces, fluids and eventual carcass, can contain sufficient residual pesticide to kill others in the same nesting site. As the roach staggers around for hours or even days, it infects other roaches in the nest, with toxicant transfer through feces,[1] which then go on to infect others. This secondary transmission occurs through direct contact with, or ingestion of, traces of baits dispersed in the environment by contaminated cockroaches. These traces were either deposited by “trampling” in the environment or on dead contaminated cockroaches.[2] The cascading effect goes on to wipe out whole colonies from indirect exposure by contact with the corpses, feces, or harborages of cockroaches previously exposed.

Such nests, when contaminated with sufficient residual pesticide via feces, secretions, exuviae, or corpses provide an important reservoir of pesticide, which would be available to infect other species. Residual pesticides by virtue of their efficacy against cockroaches, their deployment in secure bait stations, and the way in which the active toxicant is transmitted to cockroaches that have not fed on the baits, offer an effective and environmentally compatible way of controlling cockroaches.

Serious cockroach problem:

1. Cockroaches share vomit or half digested food with their companions.

2. Even more frightening is that they eat the carcass or excrement of their companions.

3. They are not only allergens such as asthma, rhinitis, eczema, but also spread all kinds of pathogens, including typhoid, cholera or food poisoning.

4. Cockroaches are mostly active at night and usually appear in inconspicuous or dark places.

%1. A cockroach appears may means there lived over a million cockroaches.

3 Steps to Kill Cockroaches:

1. The cockroaches are lured into the stations and eat the bait.

2. The cockroaches crawl out the stations after eating the bait.

3. The cockroaches will die when they back to the den and become the bait of the other cockroaches.
