Review: Effective and easy to use - This little circle got me out of trouble when I discovered my water feature was teaming with Mosquito larvae. Within 24 hours of using them the larvae were dead and they have kept the water feature larvae free all summer. They are easy to use and depending on the size of your pond or water feature and therefore how much you need to use, they are pretty good value for money. Wash your hands straight after handling if you don’t wear gloves as they are highly toxic and don’t breathe in the spores.
Review: It does work - I have a water feature approx 4m x 1m and about 150mm deep. Midge larvae appeared out of nowhere and they were everywhere happily bobbing about. Put one of these dunks in and with 36hrs they were dead. Given how quickly one dunk worked i would think a half would be more that sufficient, so one pack would easily cover 12 months +. Spring, Summer being worse of course and may need to up the dose. Nice to find a product that actually works and exceeds expectations. Highly recommended.

## Questions & Answers

**Q: Can I use this in a rain barrel that waters a food garden?**
A: Package states not to use in water meant for human consumption.  Interpret that how you would like.  Package says it is safe for fish ponds and bird baths.  I chose not to use in rain barrels.  I cover rain barrels and put this only in my buckets that I run water out of my rain barrels...used for dipping water and filling my watering cans.  If I need water for vegetable garden or bird bath, then I use fresh from spout of covered rain barrel. Does that help?

### ⭐⭐⭐⭐ Actually work!
*by E***3 on 17 September 2025*

These actually work! They stop mosquitos being able to lay/hatch larva. So you still get a few but for us after a week or so it was notably less. I put half a dunk in a bucket of water with half an apple/pear and some grass cuttings. Apparently they are attracted to the carbon dioxide from the rotting fruit/vegetation. I would recommend!
