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.

Hawks might seem like fearless predators, but these smart birds do know what other animals to be cautious around. Hawks are naturally wary of humans and predators that see them or their eggs as a potential meal or threat. This list includes owls, crows, eagles, and even snakes or raccoons.

Both spikes and loose nets can be installed over nest sites to prevent the bird from returning, but nets are not a humane option since birds and other wildlife can get tangled in them. 

Spikes are a humane alternative that deter nesting without harming the birds. In small areas, like vents, a very fine mesh net can be installed to prevent the bird from returning. These nets don't generally pose a risk to the birds.

No single deterrent will work 100 percent of the time, so we suggest combining deterrents to ensure your seed has the best possible chance to grow. Using bird netting over your seed, with physical deterrents like mylar tape coupled with hanging bird feeders at the edges of your growing area—and removing any bird’s nests, if possible—will give your seeds the best possible chance for success.
