Can Cockroaches Eat Through Caulking?

You can prevent cockroaches from entering your home by sealing cracks and holes. However, caulk can wear out and need to be replaced. This method will take time and a lot of caulk. It is best to use 100% inorganic caulk as it contains no natural gum binder, which cockroaches can’t eat.

Cockroaches will enter your home through vents or air drafts. This means you need to seal any gaps around your house and air conditioning units. You can use caulk to seal cracks and gaps around windows and doors. You should also repair damaged screens and gaps under doors.

If you notice cockroaches in your home, seal these areas with silicone or waterproof caulking. You should use a clear or white silicone sealant. This is especially important in the bathroom and kitchen because these are high-traffic areas for cockroaches. Also, make sure you seal all exposed plumbing.

Roaches love food and will find a way to get in your house if they are attracted to it. They feed on decaying wood and can chew through caulking, but they will not eat through a plastic covering that’s meant for industrial use. Also, roaches are not strong enough to chew through wood and thick plastic bottles.
