How to Clean After a Pest Infestation: When to Call the Pros
Jun 19, 2025
Discovering a pest infestation in your home or workplace can be both stressful and unsettling. Whether it’s rodents, cockroaches, bed bugs, or other unwelcome guests, pests leave behind more than just an unpleasant experience—they leave behind droppings, bacteria, shed skin, nesting materials, and foul odors that can compromise your health and comfort. Even after exterminators have handled the infestation, the cleanup is far from over.
Knowing how to clean properly after pests are gone—and when to bring in professionals—can make all the difference in restoring a safe and sanitary environment.
1. Understand the Risks of Post-Infestation Contamination
Even after the pests themselves are removed, what's left behind can be hazardous.
Rodent droppings and urine can carry diseases like hantavirus or salmonella.
Insect shells and shed skins (like from cockroaches or bed bugs) can trigger allergies and asthma.
Dead pests and nesting debris attract new pests and create foul odors.
Contaminated surfaces and food storage areas pose serious health risks, especially in kitchens and pantries.
Cleaning up after a pest infestation isn’t just about appearances—it’s a matter of hygiene and health safety.
2. The Steps Involved in Thorough Pest Cleanup
Cleaning after an infestation requires detailed attention to both visible messes and hidden contamination. Here’s what a thorough DIY process typically involves:
Wear protective gear (gloves, mask, goggles) to avoid contact with hazardous materials.
Ventilate the area by opening windows and doors during cleaning.
Remove and dispose of contaminated items like food, cardboard, or insulation.
Disinfect all hard surfaces with a strong disinfectant to kill bacteria and viruses.
Vacuum and steam clean carpets to remove feces, urine, eggs, or dander.
Clean air vents and ducts where pests may have nested or left droppings.
Seal cracks and entry points to prevent re-entry.
While this checklist can be helpful, the effort and time involved can be overwhelming—especially if the infestation was widespread or if biohazard materials are involved.
3. When Should You Call Professional Cleaners?
There are times when DIY cleanup just isn’t enough. Calling in a professional cleaning service is the safest and most effective option in the following scenarios:
Large or prolonged infestations: If the pest issue went unnoticed for a while, contamination may be deeper than expected.
Presence of hazardous materials: Rodent droppings, urine stains, and pest carcasses can pose health risks that require industrial-grade sanitation.
Lingering odors: Professionals can neutralize stubborn smells that household cleaners can’t touch.
Heavily soiled carpets, upholstery, or air systems: These need specialized equipment like steam cleaners and HEPA vacuums.
You want to avoid health risks or don’t have time: If you have allergies, respiratory issues, or a tight schedule, letting the pros handle the job is safer and more efficient.
Professional cleaners come equipped with the tools and knowledge to remove every trace of the infestation—and make sure your space feels fresh and safe again.
