Rats and mice potentially scuttling into our homes is a nasty thought, but an expert has shared a home test for those wanting to keep them away.

Callouts to deal with rats have spiked in recent years as figures show Watford Borough Council made 845 residential visits in 2023, up 28 per cent from 660 in 2021.

Glen Peskett, DIY expert at Saxton Blades Multitools, has shared “the 5p test” that can help to keep the pests out, The Mirror reports.

Expert shares 5p test you should do to keep rodents away

The DIY expert said: “Homeowners ahead of rising temperatures should conduct the 5p test.

"Take a wander around the edge of your shed or home and look closely and any gap bigger than a 5p coin should be sealed up immediately.

"The last thing you want is them entering your home and snacking on wiring, which could cause fires or shocks. Removing any entry points is going to reduce mice significantly.”


How to get rid of these common garden pests


In the warmer months, rats and mice like to search for a good nesting spot for when winter comes around.

Rats like to find shelter and keep warm plus if they can get their paws on food, they certainly will so it’s a good idea to keep all holes and gaps covered and to clean up crumbs from both inside and outside the house.
