How to stop insects and pests entering your house

If there are any gaps around the pipes going into or coming out of your house, then insects and pests are likely to get into your house. Many are harmless, but nobody likes the idea of sharing their home with creepy crawlies.

What type of insects and pests get into a house?

There are many different types of insects and pests that can get into your house through cracks, crevices and holes around pipes. In fact, according to Rentokil, the Top 10 Household Pests include:


Mice are active all year round and like to nest in lofts and cavities. They can easily get in and out of the holes where pipes enter and exit walls. 


Although many moths cannot be classed as pests, clothes moths can cause damage to your clothes and are a real nuisance


Rats can cause real damage and can spread disease. They can swim and take advantage of damaged pipework.  

Bed bugs

These little bugs can attach themselves to clothing, bags, luggage and like cracks and crevices in used furniture. 


These are parasites and tend to live on cats, and less commonly dogs, in the UK.  


Wasps can build their nests around your decking, in the eaves of your house, but they can also go undisturbed in attics and lofts until they are discovered in the spring when they emerge from hibernation. They can enter and exit your house through small gaps in your pipework and brickwork.


Like many pests, flies carry disease and are attracted by rubbish. If drains are smelly and full of rubbish then you are more likely to attract them and find them in your property.


These tiny creatures travel a long way to find their food, and telltale mounds of soil on your paving, at the base of exterior walls or on your lawn show they are nesting and potentially on the march. Any cracks or holes and they will find their way in.


Totally harmless, but with an ability to scare many people, approximately 650 species are found in the UK. The majority of these are completely harmless but occasionally people are bitten by False Widows and Yellow Sac spiders.


Wall cavities such as holes around pipes are perfect entry points for cockroaches and they like warm homes and kitchens. They tend to come out after dark, are extremely tough and breed rapidly.

Stop insects and pests entering your house

An effective and easy way to prevent most of these pests and insects getting into your home is to seal around the pipework inside and outside of your home. PipeSnug is a collar designed to create an air-tight seal around pipes where they enter or exit a wall or floor. It can be fitted externally and internally, giving a smart finish and a pest barrier, quickly. You don’t need to mix mortar or use silicone and it can be fitted in less than five seconds. It is an instant uplift to the building fabric’s integrity. The product fits into the core-drilled hole drilled for the pipework and comes in 32mm, 40mm or 110mm sizes.  

Pipes extruding from buildings have traditionally been sealed using mortar and silicone adhesives. Although mortar is tough, it is not immune to weathering and can crack and come away, leaving the cracks open to insects and pests.  Similarly, silicone sealant can also weather and fall away letting the creepy crawlies in.

Install a PipeSnug inside and outside

Your plumber or builder should install your PipeSnugs, especially if the pipework is exiting your house outside at height or you need help drilling the wall to clear out the old mortar and sealant.
