Hantavirus in Houston —
What Every Houston Property Owner Must Know
Houston’s warm, humid climate supports year-round deer mouse and Norway rat populations. Hantavirus is a serious respiratory disease carried by infected rodents. Knowing the risks — and the safe cleanup protocol — is essential before disturbing any rodent droppings.
Hantavirus Risk in Houston, TX
While historically associated with the Southwest, hantavirus cases have been confirmed in Texas. Deer mice are the primary carriers of Sin Nombre virus — the most common hantavirus strain. Houston’s warm climate allows year-round rodent activity, meaning the risk is not seasonal — it’s present any time rodents are active in your home.
🦠 How It Spreads
Hantavirus is primarily spread by inhaling dust contaminated with rodent urine, droppings, or nesting materials. Direct contact with infected rodents can also transmit the virus. Person-to-person transmission is extremely rare.
⏰ 2 Rodents in June — Dozens by Fall
A breeding pair of mice can produce 6–8 litters per year in Houston’s warm climate. Your vacant garage or attic is the warmest, safest place within range. They breed continuously once inside.
💰 Cleanup Costs: $2K–$8K
Professional attic decontamination after a significant rodent infestation typically costs $2,000–$8,000 in Houston. Pre-season exclusion costs a fraction — and prevents both the health risk and the expense.
Safe Cleanup Protocol
- Air out the space for at least 30 minutes before entering
- Wear rubber gloves, goggles, and an N95 respirator (minimum)
- Wet droppings with a bleach solution (1 part bleach to 10 parts water) — let soak 5 minutes
- Use paper towels to pick up droppings — do NOT vacuum or sweep
- Double-bag all waste in sealed plastic bags
- Disinfect all surfaces with the bleach solution
- Wash hands thoroughly with soap and water
