How to keep mice out of your London home this summer: Expert mouse control and proofing tips for London homes

London Mice Control | Pest and Rodent Control Near Me | Baiting Mice | Mouse Droppings

As the weather warms up, you might think mouse problems are a thing of the colder months. But in reality, summer is a key time to stay alert. While you’re heading off on holiday, mice are looking for food, shelter, and quiet spaces to nest; and your empty London home might be just what they’re after.

At Mercury Pest Control, we specialise in expert mice control in London. From proofing solutions to mouse baiting and prevention advice, we’re here to keep mice out for good, not just now, but all year round.

Here’s why summer mouse proofing is so important, and how to protect your home before going away.

Why do mice come inside during summer?

Mice don’t hibernate. In fact, summer can be one of the busiest times for mice inside homes, especially in cities like London with older housing stock, Victorian terrace gaps, and shared internal voids between properties.

Mice love quiet, undisturbed spaces, and an empty house is the perfect environment. If they can find a way in (which they often can through the tiniest of holes), and if there’s a food source available, they’ll settle in and nest quickly.

We often get asked why a mouse infestation has started during the summer months; especially when people are away. And the answer is almost always the same: food left out, bins not sealed, and easy access through small entry points in walls or floors.

How to get rid of mice before they move in

Before locking up and heading off, take a few quick steps to make sure your home doesn’t become a mouse magnet:

• Seal all food properly: Bread bags, cereal boxes, and even pasta packets are easy for mice to gnaw through. Move anything open into hard, sealed containers before you leave.

• Clear out bins completely: Even sealed bin lids can sometimes be pushed open or nibbled at. Take all food waste outside or ensure bins are fully emptied and lids are tight.

• Don’t forget pet food: Mice love pet food, especially dog kibble and cat biscuits left in bags. Store them in airtight plastic tubs, and make sure bowls are cleaned and put away.

• Empty the toaster crumb tray: It might sound odd, but the crumbs under your toaster are a dream snack for mice.

• Check dog chews and treats: Bones, rawhide, or soft chews left around can attract mice. Clean up pet areas before you go.

These simple proofing steps can make a big difference in stopping mice from finding an easy home while you’re away.

Victorian homes and shared walls: Why mice travel between properties

Mouse control in London’s older homes

One of the most common issues we see is mice moving between terraced or semi-detached homes. In older Victorian properties (common across London) wall cavities and subfloor voids are often shared or poorly sealed.

This means even if you’ve proofed your property well, mice can still make their way in from next door or below. And if a neighbour’s property is empty for a while, your home may become an even more appealing destination.

We’ve seen it time and time again, a single mouse sighting becomes an infestation quickly, especially if there’s a food source or quiet nest spot inside.

If you’ve been Googling “baiting mice” or “mouse poop in house”, it’s time to act quickly. The sooner the issue is addressed, the easier it is to stop a full infestation from taking hold.

Spotting the signs: Mouse droppings, scratching sounds and nesting

How to spot the early signs of mice in your home

Not sure if you’ve got mice? Here are a few key things to look out for:

• Mouse droppings (mouse poop): Small, black droppings roughly the size of a grain of rice, often found along skirting boards, under cupboards, or in loft spaces.

• Scratching or rustling noises: Mice are nocturnal, so you’re more likely to hear them at night in ceilings, walls or under floorboards.

• Chew marks: On food packaging, cables, or wooden skirting.

• Nests or shredded materials: Look out for small piles of fabric, paper or insulation in quiet corners, behind appliances or in cupboards.
