Dead Animal Smells, Art Deco, and the Secret Life of Paint Finish

Episode Date: 05/09/26 Episode Number: 458Episode SummaryThis week on Home In Progress, Dan tackles one of the most dreaded things a homeowner can face — the smell of a dead animal somewhere in the house — and walks you through exactly how to find it, remove it, and get your home smelling normal again. Then he shifts to the practical side of Art Deco: how to bring that bold, geometric style into your own home without going overboard. And finally, Dan makes the case that paint finish is just as important a design decision as color — and shows you some surprisingly elegant tricks you can pull off with nothing more than a change in sheen.In This Episode[01:46] — Dead Animal Smell: How to Find It, Remove It, and Prevent It[19:25] — Art Deco at Home: A Practical Guide[33:26] — Paint Finish as a Design ToolSegments 1 & 2: Dead Animal Smell — Finding It, Removing It, and Preventing It [01:46]Dan's son Caleb bought a house and discovered a smell that turned out to be a dead possum under the floor — frozen all winter, then very much not frozen come spring. Dan uses that story to kick off a practical, no-nonsense guide to dealing with dead animal odors in your home.How bad will it be — and how long will it last? Size of the animal, temperature, humidity, and airflow all determine severity and duration. The rough timeline:Mouse: a few days to about a weekRat or squirrel: a couple of weeksPossum, raccoon, or larger: several weeks — potentially up to two months in a warm, damp, enclosed spaceHow to find the source:Use your nose. Walk slowly, close doors to isolate rooms, and track where the smell intensifies.Check near outlets, baseboards, vents, attic hatches, crawl space doors, and under stairs.Let your pets help — a dog or cat obsessively sniffing one spot is a clue worth following.Watch for blowflies. Large, metallic-looking flies congregating indoors often indicate a nearby carcass. Follow them.Note: the smell often seems to come from vents, but pest pros say the animal is almost never inside the ductwork — it's usually in a wall or attic space near a duct run. The HVAC is just moving the odor around.Once you've found it — how to remove it safely:Wear gloves and a mask, especially in enclosed spaces.Get air moving before you start: open windows, run a fan.Do not sweep or vacuum rodent droppings — that stirs particles into the air and can spread disease. Instead, spray droppings with a disinfectant or a 1:10 bleach-and-water solution, let it soak 5–10 minutes, then wipe with paper towels and mop the area again.Double-bag the carcass and dispose of it per your local regulations.What happens after removal depends on the surface:Hard, non-porous surfaces (concrete, metal, vinyl): Clean promptly, ventilate well, and the smell usually clears quickly.Porous materials (insulation, carpet pad, unfinished wood, drywall, ceiling tile): Decomposition fluids soak in and the smell can linger — or seem to come back on humid days — long after the animal is gone. In these cases, remove the contaminated material, clean with disinfectant, and then apply an enzymatic cleaner to break down any remaining organic residue at the molecular level. This is the step that eliminates the odor rather than masking it.If you can't find or access the source: The intense phase will eventually pass on its own as the carcass dries out. While you wait:Activated charcoal bags — place them as close to the affected area as possible. They trap odor molecules physically rather than adding a scent. Recharge them in sunlight every couple of weeks. Available at most stores for around $10–15 for a multi-pack.Foaming enzymatic cleaners (like BAC-A-Zap) — drill a small hole into the wall cavity, inject the foam, and the enzymes go to work on organic material from the inside. Available online or through pest control suppliers.Use both together for best results — but be honest with yourself: if fluids have soaked into porous materials inside that wall, you may eventually need to open it up.The final step — odor-blocking primer: Once the source is removed and the area is clean and dry, if you're still worried about lingering odor, you can seal hard surfaces with a shellac-based odor-blocking primer like BIN. Important: this is the last step — a lock on a problem already solved — not
