How many weeks does this strain run? Even if you killed them all using the safest insect killer, you're going to have 2 problems. Turds, and dead eggs all in your bud, there will be a change in taste that won't be desirable.......
If it's an 8-9 week strain, try a shop vac, but imo your best bet is turn it to wax.
After it finishes, then the work comes. You're going to have to bomb, nuke your grow space, throw away any medium ya might have sitting around, chuck any containers you may have use............
Good luck.
The best cure is prevention. Keeps pets out of the area, change cloths before entering your area.....but most importantly, kill every last mite before your next run. In a commercial setting the down time would be very costly. If you're just growing for yourself, hopefully you have plenty of bud to keep you happy until everything is cleared up
