Do not try and attempt a mouse DIY remedy yourself. We have seen almost everything in the 25 years we have been in business, and the “jam a rock into a hole” technique is a well-known trick.
The problem with attempting these things is that mice and other wildlife are extremely intelligent, and will most certainly out-smart your attempts to keep them out of your home.
Often when homeowners attempt their own wildlife work, it makes things worse. They can end up damaging their home, or making additional work for a wildlife company to come and solve it professionally.
If you think you need a wildlife company at your home, don’t wait until it’s too late.
