Several steps may be taken to prevent an infestation of these common household pests. All food should be stored in containers, and all garbage cans should be properly sealed. Frequent cleaning of the kitchen area (and throughout the home) will help reduce the risk of these critters appearing. Cockroaches are attracted to wet areas, and any water leaks or dripping taps should be repaired to prevent a possible nesting ground from forming. Points of entry, such as holes in baseboards, between cabinets, pipes, doors and windows, should be sealed off with wool or copper mesh and cement, putty, or silicone caulk. Sealing all possible entries will prevent these insects from entering the home.
In the case of existing infestations, roaches can be difficult to remove. Even after all food sources are sealed in airtight containers, these pests are able to live up to three months without a meal. When large amounts of roaches have infested a building, the use of insecticides is the best resolution to the problem.
Bait stations equipped with gel (containing hydramethylnon or fipronil and boric acid) are toxic to cockroaches and may be used to kill off these pests. Bait stations that kill the insect eggs will increase the success of extermination as it helps prevent the reproduction cycle. Additionally, other pest control products (containing deltamethrin and pyrethrin) are very effective in ridding residences of these creatures. As an organic alternative to these methods, wasps are a natural predator of cockroaches. A wasp’s sting will paralyze and kill the roach, and in one of the most effective means of elimination (though somewhat cumbersome for home use).
In cases of high population, professional extermination services may be required to eradicate the entire infestation in one attempt. However, this not an easy process and requires chemical use on an industrial level.
