Can anyone conclusively identify this bug?

Looks like a sandfly, they don't seem to harm the leaves or buds but i notice their larvae (little white worm like things) in my root zone and i'm not sure how much of an issue this is.

Plants are 7 weeks into flower, and look like they have another week or two to go.

If i apply sand on top of my soil, then every time i water the sand will slowly get all in through the soil and i'll have to keep topping it up resulting in more and more soil getting into the soil. Surely this is not ideal?

Bacillus thuringiensissubspeciesisraelensis (Bti) (Gnatrol)A naturally occurring, spore-forming bacterium produced commercially by fermentation. Bti applied at labeled rates provides temporary control and is toxic only to fly larvae, such as mosquitoes, black flies, and fungus gnats. Repeat applications commonly are needed for long-term control. This Bt is a different subspecies from that applied to foliage to control caterpillars. Bt labeled for caterpillars is not effective against fly larvae.

This is the larvae i am finding in my runoff water. These are extremely small. When you look at them in the pool of runoff water, they just look like tiny specks of material. Its only when you look closely that you see they are actually moving.

Get some diatomaceous earth, or as you've been advised sand. A 1/4 to 1/2 inch will rip the little larvae as they breach the medium (stops the life cycle). Don't worry about mess, your plants roots, will thankyou with more bud for your effort. Sticky trap for the adults (they do little damage in small enough numbers).

yes they work really well actually but you can also get rid of as the previous post stated but either method to be successful you have to break up the life cycle in all stages of the gnats life

meaning you cant just kill the adult and cant just kill the larvae I highly recommend play sand even if u use the dunks

Have you used the dunks before? It seems to me the best way would be to crush it up, mix it with water and then apply that to the plants because you would get a good penetration all through the root zone. The question is how much to use - can you overdo it?

Float a dunk in a few gallons of water overnight. apply. I personally don't think you can really over do it. But, 3-4 gallons in a bucket per puck should be fine. If you get the thuricide concentrate, its 4 tspn per gallon. good luck
