Name This Bug (pic) and how to get rid of them

i am growing indoor in potting soil/vermiculite/perlite/moss vegging under floros and flowering under a 400w hps. these bugs have showed up, here is a pic of one on one of my White Sattin babies:

how do i get rid of these things inexpensivly. i heard a bug strip is good and cheap.

also, since this is my first post i was wondering if anyone reading this uses the pvc/soda bottle home made hydro setup whos plans are so common on the net. i think it would be a great first hydro setup, i am just unsure about what nutriants to get and exactly how a hydro setup works. any tips on where to get a pump super cheap? one of my freinds got his from a decorative minurature waterfall.

that looks pretty big but so does the pic. i guess a fungus gnat. use neem oil.

they are very small, they are black and have clear wings and two feelers sticking out of thier heads.

that motha looked like a mosqito in the pic, but for any bug, get a "NO PEST STRIP"
HONESTLY THE BEST!!!!

That's a fungus gnat. I used to have a problem with those little buggers, which was the result of using substandard potting soil. Once I switched to quality soil and amendments, I rarely saw them again.

There's a pesticide called Gnatrol that's tailor made to kill the adults and the larvae, and it's deemed safe for vegetables. Neem oil isn't going to be effective, as you'll need to treat the soil as opposed to the foliar growth. The adults spend their short lives in the moist soil, and the larvae feed on the roots of the plant.

Another way to cheaply limit the spread of the population is simply to let the soil dry out almost completely, which will provide a harsh environment for the insects...and will lead to many adults and most of the larvae losing moisture in their bodies, and dying. If you have a bad larval infestation, you'll actually be able to see the dried bodies spread out all across the floor. The adults live for roughly one week, and are perfectly capable of laying 300-500 eggs in that time. And while the adults aren't very damaging to the plant itself, the larvae can be devastating to the roots if left unchecked.

The yellow sticky strips will also be effective in trapping a good number of adults.

Eliminate ANY places in your grow where there is standing water or soggy dirt. Check the drip trays under your plants. If you are using pots with built-in catch saucers, REMOVE the saucer. Wash all drip trays thoroughly with hot soapy water before returning to grow room, and wipe down the bottoms of your pots. This is where they breed... eliminate the possibility of reproduction, and you eliminate the problem.

I had a fungus gnat problem and I used Gnatrol and I never saw them again. That stuff is awesome and its all natural

I'm having the same problems with fungus gnats, damn that inferior soil that contaminated my crop!

Oh, and for those who might not possibly know about the home made hydro setup, heres the detailed instructions:

Zoom!

^ thats the exact setup i was talking about. i was going to cut the bottles taller so the roots would have more room, use a longer but shorter tub at the bottom, add a few of those aquarium aeration blocks around where the pump will be. i guess i know how a hydro system works but im just slightly intimidated by mixing ALL the nutrients my plants will be absorbing myself. thats why i wanted to see if anyone used that setup so i could ask what nutrients they used.
