Fruit flies?
    #223834 - 05/07/09 02:07 PM (7 years, 6 months ago)

Over the past few days I have noticed about 10 of these tiny flies flying around my plants. It seems like they hang around the dirt mostly.  I can imagine these things getting stuck to my buds when flowering starts so I want to take care of this now.  What do you think these are and how should I kill them?

That looks more like a gnat to me. Never seem them myself, but this should point you in the right direction:

Well if its a gnat then im on my way to killing them.  When looking around for fruit fly info many people asked the same question as me and were told they have gnats.  I bought some parasitic nematodes which I just put in the soil.  Then I also got some fly paper to kill the adult gnats.  I am also planning on putting a layer of perlite on top of the soil so that adult gnats cant get to the soil to lay more eggs. 

If this doesn't work I hear diatomaceous earth will rip the larvae apart from the inside and outside.

Thanks for the help audz

I hear that a slice of potato on the soil helps draw the larvae out the soil and they burrow into the potato.

Not sure how true that is, but its the larvae you need to watch... once the fungus runs out they eat your roots.

When I was adding perlite I accidentaly broke the vein that runs through the blade on this leaf.  Should I snip the individual blade near where it is broken.  Seems kinda trivial to worry about one leaf but I am paranoid about my plants' health, especially because it is my first grow.

Na just leave it bra! Worst that will happen is the leaf will die, but in the mean time the plant can use it as for photosynthesis and a place to store food. for the time being it'sall fine and dandy.

If it can't be saved the plant will strip it of nutrients and it'll curl up and die, then you can just gently pull it off.

I remember hearing once that if you can't remove it with a gentle pull that it's not ready to come off.

Manual extermination. I've had to do it before. Works every time :wink:
