HOW TO BLOCK RODENTS FROM ENTERING THROUGH PLUMBING

SUMMARY

Rodents often sneak into homes through pipes, drains, and gaps around plumbing fixtures. This guide explains how to identify weak points and seal them effectively to stop infestations before they start.

FEATURES

• Inspect Entry Points: Check under sinks, behind toilets, and near drains for gaps.

• Use Steel Wool Barriers: Fill pipe openings and holes with steel wool to deter gnawing.

• Seal with Expanding Foam: Combine steel wool and foam for lasting protection.

• Install Drain Covers: Add rodent-proof screens to indoor and outdoor drains.

• Repair Cracked Pipes: Fix leaks and breaks that create easy access routes.

• Regular Maintenance: Keep plumbing areas clean and inspect for new openings monthly.

DESCRIPTION

Rodents are notorious for squeezing through tight spaces—and plumbing systems provide perfect pathways into your home. They use drains, gaps around pipes, and cracks in foundations to gain access to kitchens, bathrooms, and basements. Because plumbing lines are warm, dark, and often unmonitored, they make ideal entry points for mice and rats seeking food or shelter.

Start by thoroughly inspecting all plumbing areas. Look behind toilets, under sinks, around washing machine connections, and where outdoor pipes enter the house. Even a half-inch opening can allow a mouse to pass through. Once these entry points are identified, fill any holes or gaps using steel wool, which rodents find impossible to chew through. To secure the steel wool, seal it with expanding foam or caulk, ensuring a tight, long-lasting fit.

For floor and outdoor drains, use metal or heavy-duty plastic drain covers. These prevent rodents from climbing up through sewer lines. Broken or cracked pipes should also be repaired promptly, as they can lead to both leaks and pest intrusions. Lastly, maintain a clean environment around plumbing areas. Wipe away food residue, fix moisture issues, and check regularly for new openings that may appear over time.

By combining physical barriers with regular maintenance, you can effectively block rodents from using plumbing lines as their personal entryway—keeping your home safe, sanitary, and rodent-free.
