Serious problem

Need advice tiny little flies in my tent and keep coming what should I use to clean out my tent??also this has happened in my last few crops and I just put the used soil in my garden for a flower patch and d little cunts are everywhere. They seem to live around the soil only only the odd hole in the odd leaf. So I'm gonna scrub the tent in my she'd and treat the garden to get rid of all them advice plz...

Could be gnats, if you could get a picture of the bugs it would help. If your not in late flowering I would buy a neem oil based pesticide made for fruits and vegetables and 5-10 minutes before you get ready to turn your lights off spray the plant. Neem oil is a pretty good bet at fixing most bug problems. Also if it is fungal gnats you will want to make sure you aren't overwatering because 9 times out of 10 that is what causes them.

If they get really bad I have heard of several soil growers putting a layer of sand on top of their soil to prevent this as well.

Ok I just harvested a small grow yep they were in each pot and one of them had loads of little white insects too neem oil so try that how do I upload pics on this im brutal on computers tanx bud
