You should consider using frosty nuggets idea, get some TF put it on the legs, spray the perimeter with some terro, or any other and killer /traps out side the room, or any access points.
The property I grew outdoors on had a shit load of and
Ants which brought aphids on all the rose bushes all the plants on the property, I tried to prevent them by killing them off plant by plants tree by tree. Before I put any cannabis in the ground.
I began to see a high volume when I was watering the ground prior to planting, I had a yuka tree that had been cut down to about a 5ft trunk but 1/2 still being alive.I walked over to it and seen the fucking mother load , gives me the goose bumbs thinking of it, ive never seen this many ants in one spot, like something off of national geo.
Long story short I was sitting on a fucking farm, shit a fucking colony of ants that were basically running shit in this yard, they were all living in the dead half of the trunk, I hacked at that tree for a week and finally got rid of these asshole, it helped me so much with my ant prob inside and out.
I did get lucky and not saying the same might be for you, but if your having really bad problem with ants it wouldnt hurt to look on your property for a source and bring down the fucking apocolyse on those mother fuckers.
since moving indoors ive never had any problems with ants so I dont have personal exp. With ants in my grow room. But Im sure you can figure something out they have no they have 6 legs and cant fly, immobilize these fucks. Get them off the ground, make what ever you are lifting the pots with non accesible to ants. My grandma even uses DE around the perimeter of her dogs food and it helps keep those fuck at bay, they dont like that shit at all.any ways ope something works out for you.
Happy farmin;)
