Customers find the pesticide easy to use. They mention it's super easy to apply, easy to spray, and works in 10 minutes. Customers also say it'll work in all spaces, including under the sink, along baseboards, and under and behind objects. They say it can be applied through brick weep holes and makes it easy to place the insecticide only where you want it.

Customers are mixed about the sprayability of the pesticide. Some mention that it allows them to spray in crevices that normal spray wouldn't reach, and that the spray is more controlled. The little nozzle helps keep the sprays concentrated on those hard to get areas. However, others say that it didn't spray and exploded all over their porch. They also say that the nozzle was clogged and that it mostly just sprays a liquid and doesn't expand like foam should.

Need to spray quite a bit to kill
So, I just got this earlier today and my room got invaded tonight by another house centipede. I sprayed directly onto it and covered it in foam, but it still kept moving and didn't really seem very affected. I wanted to wait and see if the centipede would die from being sprayed, but I couldn't take it anymore and in the end, I killed it with my vacuum cleaner again like I usually do.I also sprayed it where my floor meets the walls and hopefully it'll prevent more bugs from popping up in my room. So far, I feel disappointed, but I guess I'll see if it lowers the amount of bugs I get.At the very least, it's nice that it dries without leaving a mark on the wall or the floor.Edit: Today, I got a spider in my room. I must not have sprayed the right area yet to prevent them from coming. Anyways, first, I sprayed the spider directly, and it kept moving, then I sprayed it a lot more, and it stopped and died pretty much right away. I took a picture afterwards to show how much I sprayed. I imagine for larger house centupedes, you'd have to spray even more to kill them.
