you can battle with them for months as i did.. or just a week , by using the ONLY solution ive found to WORK.
and its the easiest...
go to lowes and get HOTSHOT pest strips... they look like white air freshner things that plug into a wall, and they come in a blue pacakge... put 1 or 2 in your grow room.
they are sentless, and they kill ALL BUGS and DONT HURT PLANTS.
I used a spray also, but the spray was not working... and these HOTSHOTS did, and still do.
i leave 1 in my grow room for safe keeping... and NO BUGS EVER COME BACK.
Please listen to me... its so easy, everything else is hard, hurts plants, and doenst work.
Please listen to me.
