How Do You Get Rid of Rats in Your Home Without Using Chemicals?

Hey everyone!

When I discovered rats nesting in my toddler’s playroom, I refused to use poisons. Over 12 weeks, I tested ​​8 non-chemical methods​ in my 1920s Boston home:

  • ​​Bucket traps​​: Drowned 14 rats but traumatized my kids
  • ​​Electronic zap traps​​: 100% kill rate but $40 per rat (ouch)
  • ​​Predator urine (coyote)​​: Rats ignored it, but my dog marked every corner
  • ​​Structural hardening​​: Sealed 23 entry points with ​​copper mesh + silicone​​ → 90% reduction

Now rat-free, I’m obsessed with ​humane exclusion​​—but was the $2,100 cost worth avoiding chemicals?

Used ​​dry ice in burrows​, CO2 suffocates them humanely. But rats dug new tunnels under my foundation! @RatEthicsHelp Is this method banned in residential zones?

Skip bucket traps, drowning is illegal in 9 states. ​Snap traps​​ are instant if placed at 45° angles.

Built a ​rat-repellent garden​, mint, daffodils, black pepper plants. Rats left, but squirrels ate the peppers! Now using ​​motion-activated sprinklers​. Works 24/7!

Owl box + nesting materials​ attracted barn owls. They ate 3 rats/week! But owl pellets clogged gutters. Worth it? My kids think we live in Hogwarts.a

Copper mesh failed in plaster walls. Switched to ​stainless steel scouring pads + linseed oil​​. Rats hate the texture. Bonus: Fireproofing!

Live traps​ relocated rats to parks. Neighbors sued me for infesting their yards. Now using ​​rat birth control bait​. No-kill but pricey.

Dry ice requires EPA permits for CO2 emissions! Fines up to $10k. Use ​​nitrogen gas cartridges​​ instead, same effect, legal in all states except California.

@EcoWarriorMom CO2 is conditionally humane if <2% concentration. Your burrow method likely caused panic. ​​Certified euthanasia boxes​ rent for $75/day, humane and legal.

Clean pellets with ​​HEPA vacuum​​! Sell them to schools for dissections, made $200/month. Rats fund their own demise.

Linseed oil combusts spontaneously! Burned down a shed in Texas. Use ​beeswax paste​ instead—non-toxic and chew-proof.
