Can Cockroach Come Up Through Drain?
If you suspect you have a cockroach infestation in your home, the first step is to find the source of the infestation. Roaches are attracted to humid, warm climates, so they are more common in southern areas. This is where they would have access to water and food. They can live without food for weeks, but water is essential to their survival. If your drain pipes are clogged, they can cause stagnant pools of water that attract roaches. In addition to cockroaches, a leaking pipe can attract other household pests. These pests will eventually invade your home through the leaking pipe.
In addition to drain covers and metal drain screens, you can also seal cracks and holes to prevent cockroaches from entering your home. While you’re at it, you may want to consider using silicone caulk to seal cracks and holes around pipes and fixtures. You may also want to repair any leaky faucets. Finally, try not to leave standing water in the sink or tub. This will cut off a food source for roaches and discourage them from returning.
Cockroaches like wet, humid areas. Drying out your drains will eliminate their sources of water. Organic material can also provide a lot of food for roaches. It can also provide texturing on the walls of pipes, which roaches use to climb up them. If you can’t clean your drain thoroughly, you may have a cockroach infestation in your home.
