Learnt something today Baron; I never knew scarid fly and fungus gnats were one and the same.

If it is fungas gnats take washed river sand and put a inch of this on top of your medium. The fungus gnats cant dig through the sand to make babies because the sand falls on top of them. I used this last grow and problem was solved. No chemicals, no problem.

What if they are "sand digging fungas gnats" - - na, sand is prob good.

 

The underlying most likely cause of medium (compost) dwelling pest problems and their remedy is to correct poor watering practices.

 

Medium dwellers will emerge with moist composts or, more to the point, over watering & not giving the medium time to dry right out.

Mostly dont appear from no where have to come from a garden somewhere, clones that came in reused coco/soil or are spotted are high riskand need a couple of sprays day 1 then 5 days later to break there cycle. These days i just wouldnt bring fresh plant material into the grow without a bug spray.

 

Best thing you can do on or before day 1 is to use clean pots and fresh soil, spray clones for all bugs and spores, clean the grow room with peroxide/ bug spray/ peroxide wash clean/ bug spray floors and pots for lasting effect.

 

dont water to waste in coco/ soils until your pretty sure roots have spread side to side top to bottom or are growing well since planting and you can see roots in drain holes.

 

Clean fine river sand works thats forsure and so would a panda film lid on pots but those sticky traps should only be used as a guide to what you have rather than your last defence. If you disturb the soil and more of the buggers fly around and have the whole flower period togo id consider a soil drench, top soil removal and maby even Neem infused coco if its a on going problem ie not just in the hottest months.

Hi, fungus gnats love coco/soil. In all seriousness, a product called microbial, which is quaternary ammonium, basically a very mild ammonia bleach, will stop juvenile fungus gnats, and they do the most damage(feeding on fine roots). Do not use if you are using beneficial bacteria, but with enzymes is no worries. The adults don't do to much damage, and if you use microbial at 0.5 ml/l your roots will be safe. Using sand on top of your pots will reduce the plants possible absorption of oxygen as it effectively "chokes" the pot of free airflow. Adult gnats are more susceptible to sticky pads than most insects and these slow their numbers a little.

In short, healthy plants with good airflow are not fazed by adult gnats or the exposure to pythium inter-cell, and if you use a good root-zone conditioner, there will be nothing for the juveniles to eat so the eggs won't be laid there in the first place.
