Hello, my houseplants have an infestation of those teeny annoying flies, known as fungus gnats (some people also refer to them as fruit flies), and the ONLY successful treatment I have found is nematodes.
Thing is, the smallest amount I can buy is sufficient for a whole allotment, and they are a live thing (microscopic) so they won't keep.
So, as I hate waste, I am seeing who has those flies Right Now and would be interested in having a share of the nematodes to treat them. They eat the larvae, are harmless, and die once there are no more to eat. You would need to bring a small bottle to take a solution away with you. You then put it into a larger volume of water, whisk it up, and water every plant in your house with it.
I need to have people ready before I order, to be sure they will be alive for you.

Any takers?
