Those little black flying insects that hover over your houseplants are not just a nuisance. They're destructive fungus gnats, which live in soil and produce hungry larvae that devour plant roots. Gnat Guard to the rescue! A single application of this biological control (naturally-occurring beneficial nematodes) gives your plants permanent protection against gnats and thrips.

Comments about Gnat Guard:
The product took much longer to arrive than the customer service representative led me to believe. When it did arrive, the cold pack that accompanied the product was completely thawed. I can't be sure, but I have the suspicion I spent [$] for nothing.

Comments about Gnat Guard:
I wasn't sure the gnat guard was still alive when it arrived. Maybe ordering it in the spring might be more productive. Used in combination with insect spray and the bugs seemed to have decreased.

Comments about Gnat Guard:
This is the third year I have ordered Gnat Guard from Gardener's Supply. It worked very well the first 2 years and is the only thing I have found that does kill fungus gnats for a whole season. It was easy to use, clean, safe, and natural. [...].Since I applied the gnat guard, there has been no effect whatsoever on the gnats. I have many plants in pots and planters, so I ordered 3 packages of Gnat Guard. As you can imagine, I was very disappointed

Comments about Gnat Guard:
Applied the nematodes the day I received them. Haven't seen any reduction in the gnat population in the last few weeks. [...] Maybe nematodes died in transit? Felt it was a waste of money.

Comments about Gnat Guard:
I tried this several years ago and it worked really well. Then the fungus gnats returned this last year and I decided to purchase again as am sure it doesn't last forever. It seems to have been very effective again. Will see how long it lasts this time. I do like the fact that it is not a pesticide

This was sooo easy to use - just follow the instructions. I am growing a lemon tree indoors & this sure helps keep the gnats under control.

Comments about Gnat Guard:
Pricey, but it got rid of the gnats quickly and saved my living wreath. Makes a lot, so plan on treating/watering multiple plants.

Comments about Gnat Guard:
I found it easy to mix/use. I followed directions exactly, but saw no decrease in the gnats. Due to the high cost, I didn't want to try it again.

Comments about Gnat Guard:
I had never before used this product and mixing was a challenge. After the fear of not mixing had passed the product works wonders. This product makes a huge difference in plants I have brought in for the winter months. Thank you. I will purchase this product again next year.

Comments about Gnat Guard:
I found this product to be extremely effective in controlling persistent fungal gnats occurring in my indoor container garden. After trying several organic products with little success, the Gnat Guard was extremely effective. If necessary, I would definitely order this product again.
