look for organic neem oil concentrate, mix per directions and use a portable pressure sprayer or similar. If you want to be even more cautious, buy some neem cake, organic for gardens, and soak about 1/2 cup in a gallon of water for 24 hours or so, then strain it into your sprayer or squirt bottles...it’ll look like tea after 24 hours. Spray THIS all over your leaves and soil (damp not soak) to kill or repel most bugs...also consider BT concentrate to kill budworm caterpillars (moth larva) which often hatch out from stems weeks after being laid....then straight to the center of your juciest buds to eat, crap and destroy them with budrot!
