Review: Seems to work quickly - It seems to have helped get rid of most of these pests, but I have also applied nematodes to the soil of my pot plants. These worked well last time I used them but I wanted quicker results this time round so going for the double whammy! Easy to use, although the catch on the spray trigger was one I'd not seen before and small enough to be almost invisible, although an excellent idea in retrospect.
Review: Great idea shame it doesn't work - Very small amount for the price and doesn't work. Sprayed all the plants and has had no impact at all. I have a ton of yellow sticky fly catchers and they are doing a good job but no decline in numbers after spraying. Oh well bring on the Raid. As an aside I broke the spray bottle as I couldn't see how to release it. For reference it a small black button thing you move just under the nozzle,
