Description

Chemical control method Chemical control methods may vary with different species of cockroaches. The sites for chemical control of Asian, German and American cockroaches differ for each species as they will infest different areas of a structure. Asian cockroaches fly in from the outside, German cockroaches primarily infest kitchens and bathrooms, and American cockroaches prefer sewers and basements. The most accepted methods of chemical control of cockroaches are gel and perimeter spray treatments. Gel treatment quite effective in the control of cockroach pests and have replaced general spraying of baseboards and surfaces. For German and American cockroaches, gel can be placed exactly where they are most effective, especially in foraging and harborage areas. Gel formulations are used as baits in crack and crevice treatments to attain maximum exposure. The gel treatment use today provide both primary and secondary kill of cockroaches. Through primary kill there is direct kill of the cockroaches that feed on the gel. Because Our gels are often slow-acting. The cockroaches that die from direct kill do so after they have returned to harborage areas, often after they have eliminated some of the bait through their feces. The fecal material and the dead cockroaches themselves are then consumed by other cockroaches, which are then also killed by the active chemical ingredient of the gel.
