How Can I Prevent Rats from Entering My Home?

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.
