Works. Appears to habe killed off any mosquitos in the wildlife pond and I've not been bit since.

Does the job of getting rid of mosquitoes in a small water feature brilliantly.

We have a few areas of standing water and thought I’d try this as we suffer with mosquitoes in the warmer months. This works by putting a layer of silicone on the surface of the water, which prevents the mosquitoes from laying their eggs there.I tried it in a bucket of water we have in the garden and it immediately pushed the scum on the top to the edges of the bucket. It was so fast I couldn’t get a video! My next project will be our three ponds in the next monthIt says it’s non toxic, which is brilliant, as I have pondlife and a Labrador! It looks promising and I'm happy to recommend.

Sent back as not needed for my purpose. I’m sure it does what it’s supposed to.

Not as effective as the dissolving cakes previously bought from the same company but no longer unavailable. This works ok on still water but with a filtered pump and skimmer running on the pond the surface film is soon destroyed. Seems to be better in the water butts where the surface isn't disturbed as much. I used to hang the old style cakes in the butts, which overflow into the pond, and both were mozzy free (apart from the floating corpses) :).

I found a lot of larvae within a few days of building the pond. I disposed of them, put the product in. No more larvae!

Brilliant, worked straight away and 4 weeks later still no sign of larvaeDefinitely recommend

Had tried previously adding pellets and things in to the water with little success. Have added this and appears to have done the job. For now anyway
