It is the most effective one worth buying from the supermarket.
I have been getting it for many years and it always does the job.
At first, I bought it for cockroaches, but yesterday I sprayed for ants in the kitchen, which was full of them, and they disappeared.
Of course, it needs to be sprayed again if the surface gets wet or washed, but almost all products are like that.
If you spray regularly at the entry points of insects, window frames, light wells, doors, etc., you will not have any crawling insects at all.

For me, the best of its kind.

I have dealt with cockroaches, mosquitoes, flies, bees, wasps, spiders, and I think that's it, scarab beetle (with several doses) using this.

It is not for spraying in the air, but for when the target is on a surface. But yes, it works in the air too, but it's more difficult and perhaps more dangerous for the person spraying. I wouldn't want to accidentally breathe it in.

Since the first time I bought it, maybe about ten years ago, it's the only one I keep buying. Kudos to them.

I bought it to get rid of the small cockroaches that roam around the kitchen every night. I have to admit that I emptied the whole bottle, but from the first 5 minutes, I saw them lying on their backs. The fact that it is odorless is extra credit. Very honest for its price, but mainly because it does the job from the first minute.

Odorless and effective. However, "instantly," as it promises, does not exterminate, at least when it comes to cockroaches.
