Plumbing Penetrations: Hidden Entry Points For Pests

Why Are Openings Around Plumbing and Electrical Penetrations a Problem?

Openings around plumbing, electrical conduits, and other structural penetrations create entry points for pests such as rodents, cockroaches, ants, and even termites. These gaps provide easy access to food, water, and shelter—everything pests need to thrive inside your home.

Common issues caused by these openings include:

• Rodents squeezing through small gaps to nest in walls and attics.
• Cockroaches and ants using these gaps to move between rooms undetected.
• Moisture buildup, leading to mold growth and attracting additional pests.
• Termite infestations, especially if gaps allow water intrusion and soften wooden structures.

How to Fix It

To prevent pest invasions, seal all openings around plumbing and electrical penetrations with:

• Expanding foam or caulk for small gaps.
• Steel wool and sealant for rodent-proofing.
• Metal plates or mesh screens for larger openings.
• Weatherproofing materials to prevent moisture damage.

Tip: Regularly inspect areas behind appliances, under sinks, and around exterior walls to catch potential entry points before they become a serious problem.
