That sweet, heavy, getting-worse-by-the-day smell means an animal died somewhere in the structure — a wall void, under the floor, in the crawl space. You don’t have to find it. That’s the part we do.
Call while the trail is strong: 215-318-9151. Describe the room, the floor, and when it started — that’s all we need to start.
Odor tracing plus insect activity, worked wall by wall until the source is confirmed.
Recovered wherever it can be reached without cutting into finished plaster or drywall. Carcass and nest material out, bagged, and off your property.
The surface it decomposed on gets disinfected and treated. Kill the source, treat the site — that’s what actually ends the smell.
Depends on the animal. A mouse may fade in days; a rat, squirrel, or raccoon inside a wall can smell for several weeks, and the fluids it releases soak into wood and plaster, which keeps odor alive even after the carcass dries out. Waiting also means flies. Removal is the only fix that actually ends it.
You can mask it, briefly. But the source is still there, still decomposing, still drawing insects. Deodorizing works when it’s applied to the cleaned site after the carcass is out — that’s the order we do it in, and it’s why the treatment holds.
Sure enough to tell you honestly whether it can be reached. Odor is strongest at its source; combined with insect activity and a methodical wall-by-wall check, the location gets pinned down. If it is in an attic, a crawl space, a basement or under a porch, it comes out. If it is sealed inside a finished wall, we do not cut your plaster open — that is drywall work, and a rodent in a sealed cavity dries out and the smell eases from there.
Size drives it. Mice are faint, rats noticeable, squirrels strong, and a raccoon or opossum in a wall or crawl space can make rooms unusable. If the smell is strong enough that guests notice it from the front door, assume something larger than a mouse.
If you already know where the animal is located, go straight to removal from the house — or start from our dead animal removal services in Philadelphia for the full picture.
Located precisely, then recovered where it can be reached without cutting a finished surface.
