Don’t want to share my hard-won personal space.

Moved into house that was abandoned for years. Thousands of spiders, eggs and all manner of insects. But: Not Anymore!

All bugs disappear, I don’t smell any odor. Easy to spray. My only concern is making sure my dog does not lick the spray on the floor.

We live in a 100 yr old home that has a very damp back yard with lots of big old trees, damp woody yard, and a crawl space. This summer we started getting these huge American cockroaches coming in from the yard. We have no idea how they got in but after researching, it was clear that our backyard was the type of area they prefer to live in. And that they will come indoors for search of food and water. We didn’t have a ton of them, but it was enough to be annoying and disconcerting as they are quite large. We sprayed the perimeter of the house inside and out, including baseboards, doorways, and door jams, windows… Anywhere we thought they might be able to get in. At first, we did see quite a few different types of bugs, almost as if it had flush them out. but then it settle down and we can tell that it has definitely made a difference. We will be trading again in about a month since the initial results were promising. It is starting to get colder outside, and I certainly do not wish to have our home as a safe haven for the bugs in the yard! When I was researching what to use a saw this product mentioned frequently from professionals and lay people alike. It was easy to get a hold of, easy to use, and inexpensive so I thought it was worth a try. so far I am happy with the results
