Signs of a Squirrel Infestation

Squirrels can cause significant damage to buildings due to chewing on cables and support structures. Identifying a squirrel infestation quickly allows you to get help before they start breeding.

Check for Squirrels

Squirrels nest in high places - often attics or loft spaces, which make them a nuisance for homeowners and tenants. These signs will let you know if you have squirrels in your home, office, or other building.


Squirrel droppings are a good indicator of an infestation. They are similar to rat droppings, though they tend to be rounder and larger, measuring approximately 8-12mm in diameter. It can be difficult to tell the difference unless you see different pest droppings regularly, but if you have any droppings in your property, you need pest control services to deal with whatever creature is leaving them.

Sights and sounds

Squirrels can usually be found in small internal spaces, such as wall cavities, attics and chimneys. They often use loft materials as nesting materials, so you may see a pile of shredded material in your loft space or holes in your woodwork.

The most common sounds you'll hear are scampering and jumping from the squirrels running around, scratching sounds, and sometimes even the squirrels squeaking and calling to one another.


Grey Squirrels are quite strong and have sharp claws and teeth. This allows them to break through standard construction materials such as wood, fascia boards, insulation materials and even some soft metals.

You may see some damage to roofing materials and soffits, which would indicate a potential infestation. They can even chew through shingles if they're particularly determined, so look for damage on or around your roof.

You may also notice interior damage - shredded materials for nests, chewed wood or cables, stains (and smells) from urine damage.

I am very happy with the service provided by JPS environmental.

Recurring moth problem

We contacted JPS to assist with a moth problem that was not going away easily.
They were easily contactable and happy to try and fit in with demanding client schedules. Gary was very helpful and gave us lots of information and a range of options to try, returning when we called him at short notice!
Thanks very much, I believe the problem has now been resolved.

Many thanks.

Stephen Saunders, Southend Essex

Just want to thank you JPS for the prompt service and professional attitude you showed when recently you undertook the task of thoroughly cleaning and controlling the infestation of cockroaches at my mother's property.
You made what seemed like an impossible task seem easy.

Tony, Plaistow

Just wanted to say a big 'Thank You' for the great job you did for us in removing the wasp nest from our garden which was causing us a lot of stress. Everything is perfect now. No wasps to be seen. Would highly recommend you.

Lisa and Tony, Romford, Essex

We are a mansion block based in Central London for some time had an ongoing issue with roosting pigeons. We asked JPS for their advice and help. Various options were discussed with the merits for all explained and we eventually opted for bird netting with various gates to give us access on our fire escapes. It has worked a treat and solved our problems 100%. We found their team to be professional and courteous and we would highly recommend them.

Andrea Slatter (Chief Executive) of Bickenhall Mansions

Thank you for attending and providing the service. I will certainly forward any referrals. 

Tony Ashley, Aldersbrook Baptist Church

Thank you for expediting [the installation of new netting and spikes, and deep cleaning to the roof and outside the block] for me.
