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.

A raccoon may be hanging around your house for convenient access to food, water, or shelter. They may drink water out of puddles, pools, ponds, fountains, or your pet’s water bowls. Raccoons are also known to eat just about anything, including food from gardens and waste from unsecured trash cans.

A spider infestation happens when an unusually high and problematic presence of spiders occurs in a home to the point it becomes disruptive or poses a significant nuisance. If you notice an increase in spider sightings, numerous webs throughout the home, or see multiple spiders daily, it's likely you have an infestation. In cases where the types of spiders seen are venomous or medically significant species are present, the number of spiders is insignificant and would require pest control measures. On average, pest control costs between $300 to $550 for one-time service.

To determine if you have a rat or mouse infestation, look for several key differences. The most obvious is the size of the rodent: rats are significantly larger with thicker bodies, while mice are much smaller and more slender. You can also identify them by their droppings; rat droppings are larger and rounder, about the size of a raisin, while mouse droppings are smaller, like a grain of rice, and often have pointed ends. Other signs include the sounds they make, as rats produce louder scratching and gnawing noises due to their size. Behaviorally, rats tend to be more cautious, whereas mice are more curious and might be seen more often. Additionally, rat nests are typically larger than those of mice. If you are unable to see the pest or find clear evidence, a professional inspection can provide a definitive identification.
