Finding droppings inside your home, garage, attic, or crawl space is often the first sign that unwanted pests have moved in. Identifying the size, shape, and location of droppings can help determine which pest is present and how serious the infestation may be. More importantly, pest droppings can carry harmful bacteria, parasites, and viruses that may pose health risks to your family or employees.
At Go Green Pest Control, we provide professional inspections, humane wildlife removal, rodent control, exclusion services, and sanitation recommendations throughout Delta, Tsawwassen, Ladner, North Delta, Surrey, White Rock, and surrounding communities. Our environmentally responsible approach focuses on identifying the pest, eliminating the problem, and preventing future infestations.
Mouse Droppings
Size: 3–6 mm (about the size of a grain of rice)
Shape: Small with pointed ends
Colour: Dark brown or black when fresh, turning gray as they age
Mice leave dozens of droppings every day, usually near food sources, cupboards, basements, garages, and wall voids.
Health Risks:
- Salmonella
- Hantavirus (rare in Canada but possible)
- Allergic reactions from contaminated dust
Rat Droppings
Size: 12–20 mm
Shape: Capsule-shaped with blunt ends
Colour: Dark brown to black
Rat droppings are much larger than mouse droppings and are commonly found in crawl spaces, attics, sheds, and along walls where rats travel.
Health Risks:
- Leptospirosis
- Salmonella
- Rat-bite fever
- Contamination of stored food
Squirrel Droppings
Size: 8–12 mm
Shape: Oblong with rounded ends
Colour: Dark brown when fresh
Squirrel droppings are often mistaken for rat droppings but are usually slightly thicker and found in attics or around roof entry points.
Health Risks:
- Salmonella
- Parasites such as fleas and ticks
- Contaminated attic insulation
Raccoon Droppings
Size: 20–30 mm long and 15–20 mm wide
Shape: Tubular with blunt ends
Appearance: Often contains seeds, berries, or undigested food
Raccoons frequently create communal bathroom areas called latrines on roofs, decks, attics, woodpiles, and garages.
Health Risks:
- Raccoon roundworm (Baylisascaris procyonis)
- Leptospirosis
- Salmonella
Raccoon droppings should never be handled without proper protective equipment because roundworm eggs can remain infectious for years.
Skunk Droppings
Size: 25–50 mm
Shape: Tubular with tapered ends
Appearance: Often contains insect parts, berry seeds, and fur
Skunks usually leave droppings near decks, sheds, crawl spaces, and den entrances.
Health Risks:
- Salmonella
- Roundworms
- Parasites
The presence of skunk droppings often indicates a den nearby that should be professionally removed.
Bat Droppings (Guano)
Size: 4–8 mm
Shape: Small pellets that crumble easily
Appearance: Sparkly due to insect exoskeletons
Bat guano is commonly found beneath attic roosts, roof vents, or entry holes.
Health Risks:
- Histoplasmosis (caused by fungal spores growing in accumulated guano)
- Respiratory irritation
- Secondary insect infestations
Large accumulations of bat guano should only be cleaned by trained professionals using appropriate protective equipment.
Cockroach Droppings
Size: Less than 1 mm to 3 mm
Shape: Fine black specks or tiny cylindrical pellets
Appearance: Similar to black pepper or coffee grounds
Cockroach droppings are commonly found inside kitchen cabinets, behind appliances, under sinks, and in bathrooms.
Health Risks:
- Food contamination
- Triggering asthma and allergies
- Spread of bacteria including Salmonella and E. coli
Cockroach droppings are often one of the earliest signs of an active infestation.
Why You Should Never Ignore Pest Droppings
Droppings are more than an unpleasant mess. They can indicate:
- An active infestation
- Structural damage from rodents or wildlife
- Contaminated insulation
- Food contamination
- Increased health risks for your family or employees
Many homeowners discover pests only after finding droppings in the attic, basement, garage, or kitchen. Early identification and prompt action can prevent extensive property damage and reduce cleanup costs.
Professional Pest Inspection and Removal
If you’ve found unidentified droppings, avoid sweeping or vacuuming them, as this can release harmful particles into the air. Instead, isolate the area and arrange for a professional inspection.

- Bat exclusion
- Cockroach treatments
- Entry-point sealing and exclusion
- Preventative inspections
