🐭 Why So Much Poop?

• Mice defecate constantly, up to 50–75 droppings per day per mouse.
• They poop wherever they go—especially along walls, corners, and travel paths.
• A garage provides food remnants, hiding places, and nesting material, encouraging mice to settle and reproduce.
• The more mice, the more droppings—so large amounts of feces usually mean an established infestation.

🦠 Diseases from Mice Droppings and Urine

Both feces and urine can harbor dangerous pathogens. Here are some known risks:

⚠️ Diseases Carried:

1. Hantavirus – transmitted via inhalation of dust contaminated with droppings or urine.
2. Salmonella – from contamination of surfaces or stored food.
3. Leptospirosis – from direct contact with urine or contaminated water.
4. Lymphocytic choriomeningitis (LCMV) – viral infection from exposure to rodent bodily fluids.
5. Tularemia – rare but possible through contact with infected rodents or their feces.

🧼 Clean carefully: Avoid sweeping or vacuuming dry droppings (it can aerosolize pathogens). Use gloves, mask, and a disinfectant spray before removing any waste.

🧪 Pheromones in Mouse Urine

• Yes, mice release pheromones in urine, used for:
• The urine scent acts like a “trail marker,” helping other mice navigate and recognize safe routes.
• These pheromones attract more mice, reinforcing infestation patterns.

🛠️ What You Can Do

1. Seal Entry Points: Mice can squeeze through holes as small as 1/4 inch.
2. Declutter & Clean: Remove nesting sites and food sources.
3. Use Traps or Baits: Snap traps, electronic traps, or professional-grade baits.
4. Consider Ultrasonic Devices: Limited effectiveness but may help in combo with other strategies.
5. Go Green Pest Control Corp. a professional pest control for all and recurring infestations.

🚫 Cleanup Tips (Safely Handling Droppings & Urine)

1. Wear gloves and an N95 mask.
2. Spray droppings with disinfectant or bleach solution (1 part bleach to 10 parts water).
3. Let sit for 5 minutes before removing with paper towels.
4. Dispose of everything in a sealed bag.
5. Disinfect the area again after removal.
