October Wildlife Invasion? Protect Your Delaware or Maryland Home Before It’s Too Late

If you are reading this because you heard something in your attic, walls, or ceiling last night, you are in the right place. October is one of our busiest months for emergency wildlife calls across Delaware and Maryland, and the pattern is almost always the same: a homeowner hears an unfamiliar sound, is not sure what they are dealing with, and wants to know what to do next.

Here is a practical guide to identifying what you have and the correct steps to take.

Start with Time of Day

The single most useful piece of information for narrowing down the species is when the sounds occur.

• Daytime activity, especially in the morning and late afternoon, almost always means grey squirrels. They are the only common attic pest that is active during daylight hours.
• Nighttime activity is less specific and could mean flying squirrels, raccoons, bats, rats, or mice.
• Activity at dusk and again at dawn, with quiet in between, is a strong indicator of bats leaving to feed and returning.

What Each Animal Sounds Like

Grey Squirrels

Fast, energetic scurrying across the attic floor. You may hear thumping when they jump or land, and occasional chattering. Sounds are concentrated during daylight hours. Entry points are often visibly damaged, with chewed and enlarged openings in fascia or soffit.

Flying Squirrels

Softer and quicker than grey squirrels, with a lighter footfall. Flying squirrels are highly social and almost always present in groups, so you may hear activity in multiple areas of the attic simultaneously. Active only at night. They are one of the most commonly misidentified attic animals because their sounds are subtler than people expect.

Raccoons

Heavy, deliberate movement. Raccoons in an attic sound like a person walking around up there. You may also hear rolling or thumping sounds as they move or rearrange nesting material. Active at night. A raccoon entry point is usually obviously damaged, with torn soffits, bent vent covers, or a visibly enlarged opening.

Bats

Light scratching or soft squeaking sounds, typically concentrated near the entry point rather than across the whole attic. You may hear activity at dusk as they leave to feed and again around dawn when they return. Individual bats sometimes enter the living space of the home, usually young bats that have wandered from the roost.

Mice and Rats

Mice produce light scratching sounds inside walls, often at night. You may also hear gnawing. Rats produce heavier scratching and more pronounced gnawing sounds. Both species leave droppings along baseboards and in cabinet corners, which is often the first visible sign before sounds become obvious.

What Not to Do

The instinct to take immediate action is understandable, but several common responses make the situation significantly worse.

• Do not seal entry points yourself without confirming the animals are out. Sealing an active entry traps animals inside, where they will cause more damage trying to exit, or die and create a serious odor problem that is expensive to remediate.
• Do not use poison for animals in walls or attics. Poisoned animals often die inside the structure, creating odor problems and attracting secondary pests. Rodenticides are also dangerous to pets and children.
• Do not ignore it. Every week of delay is additional damage. Squirrels chew wiring. Raccoons destroy insulation. A single pair of mice can produce dozens of offspring in a matter of months.
• Do not try to handle or corner an animal yourself. Cornered wildlife can bite, and bites from bats, raccoons, and other species carry serious disease risks including rabies.

What to Do Right Now

If you have animals in a living space (not the attic), close interior doors to contain the animal to one room and open a window or exterior door to give it an exit route. Do not chase or corner it. If it is a bat, do not let it leave the room if there is any possibility of exposure to sleeping occupants, children, or pets. Call us for assistance.

If the activity is in the attic, walls, or crawl space and not yet in the living area, the situation is less urgent but still requires prompt attention. Note when the sounds occur, where in the house they seem loudest, and whether you have noticed any exterior damage. This information will help us identify the species and locate entry points quickly during the inspection.

What Happens During a Professional Inspection

When we arrive, we conduct a full exterior inspection to identify active entry points and assess the extent of access. We confirm the species based on entry point characteristics, droppings, sounds, and physical evidence inside the attic if accessible. We then present a removal and exclusion plan specific to what we find.

For most species, removal and exclusion can begin the same visit. Bat exclusion timing depends on the time of year and whether maternity season restrictions apply.
