It can be difficult to know what type of animal is in your attic until you see it. But several clues can help you narrow down the suspects:

• Sounds: Smaller animals like rats and mice make scurrying and tapping/gnawing sounds. Larger animals like raccoons and opossums make louder clambering noises. Also, note when animals are noisy: Squirrels are active during the day, while rats are busiest at night.

• Droppings: Rats and mice leave small, rice-shaped droppings (the rat’s version is significantly larger). Bigger droppings belong to larger critters like raccoons. As long as you’re not squeamish, an image search can help you identify what you’re seeing in your attic.

When in doubt, take photos of damage or other evidence and show them to an experienced pest control pro.

They can have a deterrent effect on birds to some extent. The reflective surfaces of these objects, such as aluminum foil strips, CDs, or reflective tape, create flashes of light and movement that can startle or confuse birds temporarily. However, some birds can become accustomed to these visual disturbances over time and might adapt their behavior accordingly. For a more sustained solution, combining shiny objects with other deterrent methods shared here is often beneficial for creating a more comprehensive and effective strategy for bird control.

Once the animals and their young are out of the house, remove the nest and locate any entry points. Some may be difficult to find because some animals can fit through very small holes. Once you’ve located as many entry points as possible, use materials such as metal or masonry to block off the entry. Ideally, you should choose materials that most animals cannot chew through. Create a one-way door or flap to allow animals to leave but not return. Additional methods include using repellants designed to make an area unappealing to the types of animals that find your home so inviting. 

An owl's worst enemy in the wild is often other raptors and environmental factors. Among the avian threats, larger owls or other birds of prey can pose a danger, engaging in territorial disputes or competing for food resources. Terrestrial predators like foxes, raccoons, and larger mammals may target owl nests or young fledglings. Environmental factors like severe weather conditions, habitat loss, and food availability changes can also significantly impact owl populations.
