Secure your home: A Cornish Homeowner's Pest-Proofing Checklist:
When it comes to pests, we can all agree on one thing: it’s far better to keep them out in the first place. Dealing with an infestation is stressful, time-consuming, and often costly. The good news is that you can dramatically reduce your risk with a few proactive steps.
At Cornwall PestXpert Solutions, we believe prevention is the most effective form of pest control. We’ve put together this essential pest-proofing checklist to help you turn your home into a fortress against unwanted guests.
The External Wall Check: Your First Line of Defence
Most pests get in from the outside, so this is the most critical area to secure. Take a slow walk around your property and look for:
Gaps in Brickwork: Check for crumbling mortar and gaps in the brickwork or around foundations. A mouse can squeeze through a hole the size of a pencil (6mm).
Utility Entry Points: Look where pipes and cables for water, gas, and electricity enter your home. Seal any gaps around them with wire wool and sealant.
Air Bricks and Vents: These are essential for ventilation but can be an open door for pests. Fit them with fine wire mesh covers to block access without impeding airflow.
Roof and Eaves: Check for damaged roof tiles, broken soffits, or gaps under the eaves where birds, squirrels, or wasps could get in.
Garden & Outdoor Management: Don't Invite Them In
Your garden can either be a barrier or a welcome mat for pests.
Waste Bins: Keep all outdoor bins, including compost bins, securely sealed.
Clear Debris: Remove piles of wood, leaves, or garden cuttings from near the house, as these provide perfect shelter for rodents.
Trim Vegetation: Cut back climbing plants, tree branches, and shrubs that are touching the walls of your house. These act as bridges for pests to access upper floors.
Eliminate Standing Water: Tip out water from plant pots and trays to prevent mosquitoes from breeding.
The Indoor Scan: Maintain Your Fortress from Within
Food Storage: Store all food, including pet food, in sealed containers made of metal or hard plastic.
Cleanliness: Clean up spills and crumbs immediately. Don't leave dirty dishes out overnight.
Check for Leaks: Fix any leaky taps or pipes, as many pests are attracted to sources of water.
