Rats don’t choose properties at random. They follow food, water, and warmth, and they exploit the smallest weaknesses in a building to get inside. The good news is that with a few targeted changes, you can make your home a far less attractive target. Here’s how to rat-proof your property like a professional, drawing on what our team at Northampton Pest Control sees on jobs every week.
Start with entry points
An adult rat can squeeze through a gap as small as 15mm, roughly the diameter of a 2p coin. That means almost every home has potential access points. Walk the exterior of your property and check:
- Gaps around external pipework, cables, and vents
- Loose or missing airbricks
- Damaged mortar or brickwork at ground level
- Gaps under garage doors and shed doors
- Broken drain covers or missing rodent guards
Seal small gaps with steel wool packed tight and finished with mortar or expanding foam. Rats can chew through silicone, plastic, and timber, but not steel.
Check your roofline
Many people assume rats only come up from the ground, but roof rats and brown rats both climb easily. Inspect roof tiles, fascia boards, soffits, and the junction where extensions meet the main building. Overhanging tree branches act as motorways straight to your loft — keep them trimmed back at least a metre from the house.
Remove easy food sources
A garden full of food is a rat magnet. Practical steps include:
- Store bird seed and pet food in metal or thick plastic containers
- Don’t overfill bird feeders; clear fallen seed daily
- Keep compost bins sealed and avoid composting cooked food
- Move firewood and stored materials away from external walls
- Empty outdoor bins regularly and keep lids tight
Fallen fruit from apple or pear trees is a particularly common attractant in Northamptonshire gardens.
Manage water sources
Rats need to drink daily. Fix dripping outdoor taps, clear blocked gutters, and remove standing water from pots, paddling pools, and water features when not in use.
Declutter the perimeter
Rats love cover. Long grass, dense shrubs against the house, stacked pallets, old furniture, and overgrown decking all provide protection from predators and easy nesting opportunities. Keep a clear, maintained strip of at least 30cm around the base of your property.
Inspect drains and sewers
A surprising number of rat infestations enter through damaged drains. If you have an older property, or you’ve recently had drain work done, ask a professional to camera-survey your sewer line for cracks or displaced joints.
Don’t ignore the early signs
Even with the best prevention, infestations can happen, especially in winter when rats seek warmth indoors. If you spot droppings, hear scratching at night, or notice gnaw marks, don’t wait. Early intervention is dramatically cheaper and faster than dealing with an established colony.
