Is it a squirrel, a raccoon or something else in my attic?
Squirrels tend to be active in daylight, with quick scampering and scratching at dawn and dusk. Raccoons are mostly nocturnal, heavy and loud, and often travel through a chimney or torn soffit. Mice and rats sound lighter and move inside walls. A technician confirms by looking at the entry point and droppings.
Sound is a useful clue but not proof. A flying squirrel, a bat or a stray cat can all produce noises that people describe as squirrels. Droppings differ too: squirrel droppings are small and oval, raccoons leave larger piles in latrine spots, and rodent droppings are small and pointed.
If you cannot tell, take a photo from a safe distance and describe what you hear and when. The answer changes the plan, because an animal that is in the attic is not always the one that caused the damage.
Why is sealing more important than trapping?
Trapping removes one animal, but the opening stays and the next one can move in. Sealing with durable materials after removal is what actually ends the problem. Without it, you can pay to remove animals repeatedly from the same hole. A good plan ties removal and sealing together, even when they happen on different visits.
Squirrels and raccoons are strong chewers and diggers. Foam, tape and thin screening do not hold them for long. Heavy gauge mesh, metal flashing and properly fastened caps do, though even these depend on installation.
A technician also looks for secondary openings. Animals often use more than one route, so closing only the one you can see leaves a back door open. The inspection and the sealing plan are where most of the work lies.
What if there are babies in the attic?
Do not seal the entrance. Separating a mother from her young is cruel, causes dead animals in the wall and brings odor and flies. The technician looks for signs of a nest first and may remove the young with the mother or wait until they can leave. Tell us on the call if you hear squeaking.
Squirrels and raccoons often raise young in attics in spring and again in late summer, but timing varies. If you hear high-pitched chirping or squeaking, say so when you call.
The plan may combine a one-way door with a retrieval of the young, or a short wait until they are mobile. A technician should walk you through the approach before starting and explain any limits on what is possible.
What should I do about droppings and damaged insulation?
Do not sweep or vacuum droppings yourself. Dry droppings can carry disease organisms and release dust into the air. Contaminated insulation, nesting material and urine-stained areas may need removal and treatment. Ask the technician whether cleanup is included in the quote or a separate service, and what protective gear is used.
Raccoon latrines in particular can hold roundworm eggs, so they should be handled with protective equipment. Insulation that has been soaked with urine loses its value and keeps smelling.
Cleanup is often a separate step from removal, and you may want to wait until the animals are gone and the openings sealed. That way you are not paying to clean a space that is still being used.
