What is the Best Way to Seal Pest Entrances?

Hi everyone!

I recently discovered ​mice and ants​ sneaking into my house through gaps I didn’t even notice! I’ve tried stuffing steel wool into cracks, but pests keep finding new entry points. I’m worried about using the wrong materials or missing hidden spots. What’s the ​​most effective way to seal pest entrances​​ for good?

Steel wool + caulk​​ is the gold standard for rodents! Mice can’t chew through it. For ants, seal cracks with ​​silicone caulk​, it’s flexible and weatherproof.

@NatureLover64 Thanks! Does steel wool rust over time? I’m worried about moisture in my basement.

Use ​​copper wool​​ instead, it’s rust-proof and just as effective!

Avoid expanding foam alone, pests gnaw through it. Pair foam with ​metal mesh​ for durability. Check gaps around utility lines and roof vents!

Door sweeps and weatherstripping​ ​ made a huge difference! Sealed my garage door gaps for $15. Also, use a ​​flashlight at night​ to spot ant trails.

Don’t forget ​chimney caps​ and ​​vent covers​! I installed 1/8-inch mesh screens, kept out birds AND raccoons.

For tiny cracks, ​​diatomaceous earth​​ mixed with caulk works wonders. It’s non-toxic and shreds insect exoskeletons.

Thermal cameras​​ help find hidden gaps! I rented one and found a hole behind my fridge. Sealed it with ​​aluminum flashing​​.

Are ​​essential oils​​ (peppermint, eucalyptus) safe to spray around sealed areas? I don’t want to attract more pests.

@WorriedParent Oils can deter pests temporarily, but they fade. Focus on physical barriers first!

​Check your foundation​ for crumbling mortar. I repointed mine with cement and added a gravel barrier, no more centipedes!
