Did you know neem oil is used as a birth control for humans in India.

Anyway it works but results take time a good couple of weeks. Great as a preventative measure.

I wrote this to someone else earlier today hope it helps....Neem oil is great to use mixed with a mild soap and iso at 1 oz. per gallon. This will stop them from breeding yet it takes a couple of weeks to work. You are most likely using pyrithium which is good but can burn the plants if you drench them. Alot of the mite breeding takes place in the medium so make sure you spray it as well. Preditor mites are good to. They eat spider mites and when the food source runs out they eat themselves. Spraying your plants down with straight water before the lights go out is very helpfull as well. Diatenatious earth (food grade) is a good defense when dusted over the top of the soil. It is made of razor sharp fossils harvested from lake beds that will not cut you but when insects with exoskeletons crawl through it they cut their bellies and dehydrate within 24 hours usually. They are on the undersides on the leaves and suck the juice from the stomas mostly so make sure to wash the undersides of the leaves. I have grown many plants and have never seen any holes in the leaves so I dont what to tell you about that. If you got CO2 you can crank it and sufficate them aswell. To slow down the breeding you could make your own with sugar and yeast. one cup sugar to .6 gallon water with 15ml yeast. That mix is good for 20 sq feet. My room was a bit larger so I use 7 gallon camping water storage containers outside the room with garden holes coming through the wall in back of a fan.
For your leaf eater problem all I can recommend is get the hottest peppers you can find and make a tea out of them and spray the plants with them. The plants dont mind but the critters hate it.
One love
