Ultra hard to tell if it works
I mixed this with another pesticide that has three different chemicals. No sign of any bed bugs after spraying thoroughly, but time will tell.

Don’t be under the illusion that this product works
We’ve bought this bedbugs spray and we can almost guarantee that it has only 3% chances of killing bedbugs, when found we’ve directly sprayed them and 10mins later they are still running around freely as if we didn’t spray them. You have to drench them only then you might get some soft off result. We found that this other product called bedbug killer killed with on spray when sighted however this product not effective at all, big disappointment. Smell there’s no smell value for money no worth it at all. But easy to use

Kills on contact
I was sceptical but I have active bed bugs in one room so when I tested it I shot the bug with the spray bottle twice and it was dead that's the ones I didn't steam first. Cannot say about the eggs as I'm unsure yet for a few weeks if it's fully working for eggs so fingers crossed. Once it's all cleaned out to bare minimum I'll douse it all in the product and hope for the best. But definately kills on contact
