Squirrels often find their ways into attics and under decks.  They find tiny holes in your roof and start chewing their way in.  This can be annoying for the home owner who wants to sleep at night.  Home owners may hear scratching and running around.
For attic removal, we typically exclude them from your home and then come back and seal up the hole.  We will inspect your attic to see if there are any babies and remove them if necessary.  For squirrels under decks and sheds we often use live traps to relocate them.
