Roach bait is a modern pest control alternative used for the extermination of cockroaches at indoor locations. The effectiveness of this method of pest control exploits the cannibalistic and coprophagic tendencies of cockroaches. For baiting to be effective, proper placement and techniques are a must. One should avoid spraying insecticides in baited areas, as that can cause the bait to become contaminated, thus the roaches would likely avoid consuming it. Baits and Insect Growth Regulators can be useful in many cases. Technically speaking boric acid is not a bait in the dry form, but rather broadcasted as a dust, that is both a toxin and a desiccant. Boric acid is often formulated into a paste. Roach attractants are mixed with the boric acid. It is similar in consistency to toothpaste. The boric acid baits are great because of their low toxicity and ease of use. You don''t need to look for the roach nest. The roaches will take the bait back to the nest. In most cases, one application and you can rid your home or roaches for up to one year.
