Essential control of box moth caterpillars
After quite a lot of research with controlling box moth, I settled on this option, being reasonably cheap and apparently effective. I sprayed it on, as the instructions implied, and waited. Wow. Loads of dead caterpillars and the box shrubs, which are all over my garden, grew back. I had to buy another one to follow up treatment but it’s better than losing the shrubs as they were eaten down to the stalk. Me one, bugs nil.

Great bug killer

Great product, buy buy it locally
Great product,works well,only issue is with the shipping, its a liquid in a bottle with a trigger put in a box so it leaked in the box. Buy it locally if you can as Amazon packing not fit for purpose

It works!
Quick delivery, good price, seems to be keeping bugs away. I had a raspberry plant with lots of aphids and this done the job. Thanks

Very disappointed!
Spray was leaking slightly and the spray got stuck many times , I was not very happy about these issues so I probably wouldn’t buy again.
