Removal procedure
- Cut a small opening at the identified spot.
- Wear disposable gloves and a mask.
- Extract the body with a sturdy tool such as pliers.
- Place the remains in a sealed bag and dispose of them according to local regulations.
Cleaning and disinfection
- Scrub the exposed area with a solution of hot water and a commercial enzymatic cleaner.
- Rinse thoroughly and dry completely to prevent moisture buildup.
- Apply a disinfectant approved for indoor use, allowing the recommended contact time before wiping away excess.
Odor neutralization
- Sprinkle baking soda over the cleaned surface, let it sit for several hours, then vacuum.
- Alternatively, use activated charcoal sachets placed under the floor for 24‑48 hours.
- For persistent odors, apply a fogger containing an ozone‑generating agent, following safety guidelines and ventilating the area afterward.
Prevention
- Seal cracks and gaps in the subfloor to block future entry.
- Install a moisture barrier if dampness contributed to the problem.
- Conduct periodic inspections of crawl spaces and basements to detect any new infestations early.
