little black flies, but no leaf damage... WTF???

newbiegreengrow · 09-03-2007, 05:57 PM

got these little black flies everywhere, but my plants show no sign of damage anywhere... about the size of a fruitfly,maybe just a bit longer, and they look a bit thinner than a fruitfly. lil' cocksuckers are everywhere... Indoor grow, I water every other day, using seaweed extract and fish emulsion, along with dried blood and bonemeal. could they be eatin the blood and bonemeal?
I don't get it. Also sprayed the little bastards with ortho vegetable bug spray, and it didn't hurt them a bit....
any clues?
I could try to get a macro photo of one, but the're pretty small...

Could be fungus gnats or some other type.

To be safe, i'd get some neem oil, mix with a wetting agent, such as dish soap (not antibacterial) and spray both sides of all leaves.

Better safe than sorry eh?

Fungus gnats feed off the roots and nutrients in the soil. They especially like baby clones. Get some Vapona no pest strips or little yellow sticky squares to catch the bugs before they lay eggs.

yea pictures would help
by your description they sound like fungus gnats

newbiegreengrow · 09-03-2007, 07:44 PM

here are some extreme closeups of the little fuckers...
these things can be bad news, eh?
the plants look super healthy... nice and green, compact growth, no wilt or leaf twisting...
I guess the maggots, or larvae can eat on the root structures, or even introduce root fungus.
how to get rid of them?

Shaggy_420 · 09-03-2007, 07:49 PM

those are some ugly-ass bugs
they sorta look like babie wasps (hence the abdomen and antena)

newbiegreengrow · 09-03-2007, 07:53 PM

yeah, but they're PUNY as fuck... they'd have room to dance a jig on a pin-head.

Shaggy_420 · 09-03-2007, 08:04 PM

hmmm
if you dont find an answer in like 1 hour then google it

newbiegreengrow · 09-03-2007, 08:09 PM

I'm thinkin they might be those fungus gnats...

**slunt** · 09-03-2007, 09:09 PM

Don't look like the gnats I've seen. Was your soil sterilized before you used it? Looks like something that hatched out of the soil, but might not be plant harmful.

newbiegreengrow · 09-04-2007, 03:50 AM

The soil is a mixture of soils that I bought from a very reputable business here...
some seaweed compost, some manure, some shellfish compost, vermiculite, and sphagnum moss. I have no idea about sterilization, but my immediate guess would be no. I'm thinking that they might have been in the soil...
so you're thinking that they are NOT the fungus gnats?

**slunt** · 09-05-2007, 12:14 AM

I'd do my best to kill them anyway. Dr. Doom gas bomb might work or a raid bug killer bomb.

newbiegreengrow · 09-05-2007, 03:35 AM

hmmmm...
guess what else I found?
In checkingeverything out, I noticed a little yellow spot on one leaf on one plant in the rear of my room...
Spider mites.
I'm thinking that all of these little critters could have been brought in with all of the organic soils and composts...
I douched everything down with Safer's spray yesterday afternoon.
I'll keep you guys posted...

Spider mites tend to congregate on the bottom of the leaf, so make sure the underside gets a good soaking. Repeat procedure in 3-4 days and again 3-4 days later to break the egg-larva-adult cycle.

good info, slunt... will do.
I just rechecked, and everything looks clear so far

Now that you know you have them, a little preventive maintenance will control outbreaks.
