Nixalite Copper Blocker Pest Stopper 100ft Roll

This is what my exterminator company uses. It scrunches up to fit in small spaces. Buy more than you think. MUST WEAR GLOVES,AND WHEN CUTTING, DO SO OVER AN OPEN PAPER BAG, or you will have copper shreds everywhere. Gloves and cutiing/taring over a container are true fir all similar products like this and steel wool. It did stop mice from coming in for 2 locations It just took far more than i thought.. i will get more if needed. BYW those nite lights plug in that emit high frequency sound, are very efficient. But then I bought enough for at least 2 in EVERY room out side walls. Buying a 3 pack for 20.00 will not do anywhere near enough. I spent about $120 to 140....now , between blocking known entrances AND lights EVERYWHER there are NO mice at all so far.

It does not deteriorate. It keeps all critters out of your house attic by plugging any size opening.

It can certainly be pushed into tight places mice would try to get through and they're not able to chew through it nor does it rust. The copper links do have a tendency to make a little mess when you cut through but overall it seems to seal up the openings you can find.

We purchased this to assist with keeping snails and slugs at bay in our yard. It has done absolutely nothing to stop them. Most mornings I walk out and there are snails and slugs slithering on top of the copper to get to our fruits/veggies/plants. May work well for closing gaps in walls for other rodents but would not recommend for snails/slugs.

Beetles & Hornets no longer build nests in the vent holes. Simple solution.

100' turned out to be way more than I needed. But I'm glad I got it. Little critters have not gotten into crevices since I stuffed them with this copper. Yes it turns a dark color, the wife doesn't care for the color; but if you can see past that, then you might find it works quite well.

Product is good quality. Not an easy task to stuff between foundation and settled wood footer. Expect it to be effective but need time to prove it.

Easy cut to size. Fills gaps. Used in conjunction with Great Stuff Pest Block foam. Did the job.
