How Long Do Cockroach Baits Expire?

If you’ve been wondering how long do cockroach baits last, read on for some information on the subject. Basically, roach baits are a mixture of food and insecticide that entice roaches to feed on it. There are different types of bait available, and each works differently to attract different species of roaches. Some are gels, while others come in flowable dust or in bait stations. Gels tend to be the fastest acting, but they also tend to dry out after a while. Other forms of bait have a longer lasting effect and are usually used in conjunction with each other.

Cockroach baits should be changed every two weeks or when the bait is no longer effective. However, it is best to replace them more often than when they are first applied, because cockroaches can quickly eat through them. Most gels should last about 7 days, but you can swap them for fresh ones. If you use bait stations, you should change them every two weeks or when their liquid starts to dry out.

Gel baits are great for indoor roach problems, and are best placed in cracks and crevices. They work by disrupting a chain of chemical signals that are essential to a roach’s life. These baits can kill a single roach, but it takes a week or two for the entire colony to be destroyed.
