Identifying the specific animal running on your roof at night can be challenging without direct observation. Common nocturnal roof visitors include raccoons, squirrels, opossums, and rats. Raccoons are bigger and can create heavy thumping sounds. Squirrels are agile and may produce rapid scurrying noises. Opossums tend to move stealthily with less noise. Rats can make scratching or gnawing sounds. To determine the culprit, look for signs like footprints, droppings, or damaged areas near the roof. For accurate identification, consult a pest control professional or set up wildlife cameras near potential entry points.

If they find a hospitable spot with shelter, water, and a steady food source, there’s a good chance groundhogs will return—or not leave at all.

Bobcats are most active from sunset to midnight, and from sunrise to a few hours into the morning. If you see a bobcat acting strangely in hours they’re normally not active, it’s possible they’re sick. The Humane Society recommends contacting a local wildlife professional to find and trap the bobcat in this case.

The time of day that most snakes are active is at night. This is when they prefer to hunt since they can do so under the cover of darkness, out of sight of predators and the prey they stalk. However, some snake species prefer very hot temperatures and are strictly active during the day.
