Bed bug
So far it's not too bad. It does help but more of a contact defence. Kills on contact but so does bleach. I'll come back and update as its only been a few days but we have noticed a difference

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
