As temperatures begin to drop, rats will be looking for somewhere warm and dry, making now the ideal time for homeowners to give their properties a quick check for gaps or holes. Home insurance specialists at Tiger.co.uk have outlined essential measures on how to prevent an infestation before the autumn weather arrives.
Rats are a fairly frequent presence in Welsh gardens, especially where they can readily access food, water, shelter or appropriate nesting spots. Bird feeders, scattered seed, unsecured bins, compost heaps, fallen fruit, pet food and ponds can all offer appealing sources of food or refuge for them.
Why rat infestations are expected to rise
Householders throughout the UK are being advised to take steps to protect their properties from rats this autumn, as specialists caution that a spike in rodent infestations could result in expensive repair costs. Summer 2026 was the hottest on record for the UK, producing perfect conditions for a bumper breeding season.
As temperatures start to fall and wetter weather arrives, rats desert their burrows and commence their yearly migration into our homes searching for food. With calculations placing the number of rats in the UK somewhere between 10.5 and 120 million, it's vital that householders know what to look for.
Signs of rats and potential damage
Indicators of rats include droppings, rub marks, and gnawed holes in bags of food.
Ian Wilson, home insurance expert and managing director at Tiger.co.uk said: "Rats aren't just a nuisance; they can turn into a very expensive problem for homeowners."
"From chewing through electric cables and pipes to damaging insulation and woodwork, a rat infestation can cause severe damage to a property in a short space of time."
"As vermin infestations are typically treated as a preventable maintenance issue on standard policies by most insurers, it means homeowners could be left picking up the repair bill themselves."
How to protect your home from rats
Maintain cleanliness: Kitchens, pantries and food storage areas should be kept tidy and clear of any crumbs or spillages, and food should be stored in airtight containers.
Reduce outdoor attractions: Don't leave decomposing food in compost, remove garden debris where rats might nest, and cut back any trees or shrubs so branches aren't positioned too near to the house.
Use deterrents: Deterrents such as peppermint oil, ammonia, or ultrasonic devices all prove effective in helping to keep rats at bay. Peppermint oil is available for £2.99 on Amazon or from Superdrug for £4.99.
The powerful scent produced by peppermint oil can be disagreeable and overpowering for rats. Consequently, it can function as a barrier and prevent them from accessing your home.
