I am taking the liberty to speak on behalf of most wildlife removal companies. When we seal a home, we seal the current entry points and the common back-up entry points known for all species. However, sometimes (twice in the history of our company) they can come on a manner which is completely unexpected or anticipated and not covered by any warranty. Squirrels can be psychopaths! However, 99.9% of the time - we antipated their every move and won!
For the record this was not covered under our warranty, however, we still handled it for free. Customer service goes a long way... we hope!
