After getting rid of my couch, I have used this on my new furniture and along baseboards behind. So, far so good.

Works great!
Color: Aerosol Size: 1-Pack
This was shipped with a food item. Cap was off and there was some spray in the box. It was not much and the can did not appear to be missing much but seriously, who packs poison with food??? Anyway I'm not going to hurt the product review with that. The product seems to work well. Have these tiny bugs that nothing seems to kill and this worked well. It doesn't have an unpleasant smell but I still wear masks spraying poison. It did drip on a cloth item and it stained it. So be careful around fabrics. I have wrist issues so not having to squeeze a handle was very convenient. Other than the staining issue, which I admittedly have not tried to remove yet because it was not a concern, highly recommend! ... show more

Works great, just needs to spray better
Color: Aerosol Size: 1-Pack
Works great, used on my wooden bed frame and edges/seems of my mattress and box spring, haven't felt a bite since Only complaint is the spray isn't always consistent, sometimes foam, sometime a liquid spray or it even stopped completely, had to stop and reshake it multiple times
