Do They Cause Damage?
Grey Squirrels can cause considerable damage. Nesting activity in attics will result in damage to insulation, stored items and sometimes wiring. Damage to siding, soffits and fascia boards occurs as the gain access to areas to build nests. If they gain access to living areas (usually via the chimney) they will go to the windows and try to chew their way out, possibly doing thousands of dollars in damage.
Do I Have An Infestation?
Repeatedly seeing squirrels on the house or roof is a good indication they may be nesting there. Finding entry holes in siding, soffits and fascia boards. Gnawing damage to window frames inside the home. Hearing activity in the attic, or other void, around dawn and dusk could indicate a squirrel nest.
What Can Masters Touch Do?
A thorough inspection is required to determine if squirrels are nesting in the structure and how they gained access. Exclusion devices can be installed on entry points that allow them to leave the structure but not return. In some cases, live trapping may be done in addition to, or in place of exclusion. All potential entry points must be screened/sealed and chimneys capped to prevent re-entry.
How Can You Help?
Trimming trees so they do not touch or overhang the structure can make it less attractive. Also keeping the exterior in good condition by repairing missing and rotting trim can help prevent entry. All chimneys should have a cap or animal guard installed.
Grey Squirrels often have two litters of 2-4 pups per year, one in the spring and a second in late summer/early fall. These also tend to be the peak activity times for squirrels nesting in structures.
