Spring is when animals look for nest sites. A one-hour check now can prevent a long summer of noise.

Check the roof edge

Look for gaps where the roof meets the wall, chewed soffits and loose fascia. Squirrels and raccoons pick the weakest spot.

Check vents and chimney

Make sure roof vents, gable vents and dryer vents have heavy screens. Cap the chimney, and check the cap for rust or gaps.

Check the yard

Trim branches back from the roof, move woodpiles away from the house and look under decks and porches for digging.
