Your Questions

Still have a question?

Call 615-357-7797

What should I do if I hear noises in my attic?

Do not seal anything. Note the time of day and the type of sound and call us. A daytime scratch is often a squirrel, while night thumping can be a raccoon, a rodent or bats.

Will baby animals be left behind?

No. We check for young before any work and time removals so mothers and babies are removed or reunited together.

Do you handle bats?

Yes. Bats are protected and need careful timing, so we use one-way exits outside the pup season and seal the building afterward.
