Raccoons often enter a home through unkempt chimneys, but can also find their way through deteriorated wood, eaves, ridge vents or gable vents.

They can enter a hole 4.5" wide

Raccoons are less active in the cold months but can overwinter in the shelter of home attics without detection.

Raccoons are carriers of the roundworm parasite which passes through the feces. If dried feces is disturbed and inhaled or ingested, humans can contract roundworm which can cause death or brain damage.

Raccoons can also carry diseases like rabies or leptospirosis, a bacterial infection passed through urine.
