Poison-free rat control is possible. You can keep those pests out and pets safe with this Simple Solution.

Rats can get into holes as small as the size of their heads. Not only can they fit into tiny holes, but they also chew open smaller holes to fit inside them. 

Rats chew constantly because their teeth are constantly growing. And with this constant chewing, their teeth become sharp enough to gnaw through some unexpected material.

You can seal up holes around your home with an expanding foam sealant. However, this is only a temporary solution. The rats can easily chew through and re-invade your precious space.

Reinforce the foam by adding something that will be more difficult for the pesky critters to chew through.

Pressing steel wool into an A/C refrigerant line hole for poison free rat control.

Plug holes outside your home with some stainless steel wool before you seal them off. There is a stainless steel mesh specially made for rodent control, but you can also use a stainless steel wool scrubbing pad that you use to clean pots and pans. 

Just stretch out the scrubbing pad so it fills all around the hole. Press the stainless steel wool about an inch into the hole.

Spraying Great Stuff PestBlock into an A/C refrigerant pipe hole to block out pests for poison free rat control

After you’ve plugged the hole, you’ll need to spray more expanding foam to seal it up. Instead of a regular expanding foam sealant, pick a pest-blocking foam sealant specially made to deter rats. 

The main ingredient that deters rats in pest-blocking foam sealants is capsaicin. Capsaicin is the active compound in hot peppers that makes them spicy. Also, it’s used in muscle pain-relieving lotions like Bengay and Icy Hot.

If you do, however, have one determined rat that chews through the pest-blocking foam sealant, the steel wool acts as an extra barrier to keep that rat out.
