Review: Use for fungus gnats too! - This product is well known for mosquito control but how happy was I when I discovered a dual use?! So I have some potted plants, some are outdoor and others are indoor that I set outside on occasion for natural sunlight (my windows do not get direct sun). These darned flies started infesting my plants, flying everywhere, with the occasional up the nose. I tried neem oil (also from trying on mosquitoes with zero effect), the sticky things, watering less, and mulch. none of it has worked. One day, I’m bucket watering, you know setting pots in a bucket of water as a gnat prevention (instead of watering from the top where the gnats live) and in goes a dunk for mosquitoes. Before I knew what was going on, no more gnats! So, now I grab a dunk, mash it up and it goes in the watering can. Also take some of the grinds and sprinkle liberally in the plant pots - right on top. Stuff is amazing! ## Features - Sold on desertcart ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003NZRX36 | | Best Sellers Rank | #26,063 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #49 in Beneficial Pest Control Insects | | Brand | Gardener's Supply Company | | Brand Name | Gardener's Supply Company | | Customer Reviews | 4.5 out of 5 stars 492 Reviews | | Global Trade Identification Number | 00018506001117 | | Item Type Name | Summit Chemical Co.

Stuff is amazing! ### ⭐⭐⭐⭐ Part of my perfect mosquito repellant recipe! *by D***N on July 16, 2025* My neighbor has a lot of areas in their backyard where water collects when it rains so mosquitoes have been out of control! I purchased some collapsible buckets from Amazon which I fill halfway with water, add a few yard clippings and a small bit of fruit, then I crumble half a dunk in the buckets. So far I've been able to sit on my back deck without being attacked as I usually would have by now. I feel good that I'm doing something that's not harming the beneficial insects or the planet. I purchased the 20 dunk pack and, since I only use half of a dunk per bucket, I think this will easily last me through the summer. ## Frequently Bought Together - Summit Chemical Co.
