Hey everyone,
After rats gnawed through my garage door seal and birthed a colony in my HVAC system, I spent $2,800 testing every rodent-proofing method in my Seattle home. Here’s the brutal truth:
- Steel wool + caulk: Failed in 3 days—rats shredded it into nesting fluff
- DIY peppermint spray: Attracted curious raccoons instead
- Professional exclusion: Sealed 67 gaps with stainless steel mesh + hydraulic cement → 100% success (but cost $1,500)
Now I’m obsessed with rat physics, they can squeeze through holes as small as a quarter! What low-cost hacks actually work long-term?
Steel wool rusts, use galvanized 19-gauge mesh. Rats can’t chew it. Seal with fire-rated foam (prevents flammability risks). 50 DIY kit betas 300/month sprays!
Built a rat-proof compost cage with ¼” hardware cloth + cinder blocks. Buried 12” deep. Zero invaders in 2 years! @ExterminatorDave Will galvanized steel leach toxins into soil?
Landlord won’t fix gaps! Lined baseboards with Xcluder rodent-proof fabric (feels like steel wool but indestructible). Temporary fix until I move. Works better than legal threats!
Ultrasonic devices wasted $200. Rats partied harder. Switched to ammonia-soaked rags near entry points, stench mimics predator urine. Gone in 3 nights (but kids hate the smell).
Restoring 1900s craftsman, can’t alter original wood. Used copper wool + borate wood preservative. Rats hate the taste! Bonus: Kills termites. 10/10 for vintage homes.
Installed AI motion sensors on gutters. Alerts when rats climb near roof. Paired with automatic strobe lights. Like a disco for pests, 86% fewer sightings.
Galvanized steel is zinc-coated, safe for soil but rinse after cutting (sharp edges!). For compost, add food-grade diatomaceous earth to deter larvae. No toxins, just desiccation!
Ammonia risks groundwater! Try predator decoy rotation, move owl statues weekly. Rats think new predators moved in. My raccoons fled too—bonus!
Arizona rats laugh at gravel moats. Used cactus spines + crushed glass around foundations. Harsh but 100% effective. Wear Kevlar gloves during install!
Your AI setup costs more than my rent! Used dollar store mylar balloons tied near gaps. Reflective movement scares rats. 5 fix > 500 tech.
