yep. use 1 tsp/gal and drench your buds. I find any more than 1 tsp/gal earlier in bloom will cause brown hairs.
Make sure you do it on a warm day so the buds don't stay wet and mold.
Likewise, you can use plain water to rinse off the buds a few days before harvest.
if you're 2 weeks from harvest and the eggs were laid recently (meaning you haven't seen a single caterpillar or egg yet), then they won't hatch in time and grow fast enough to do much damage to your buds anyhow. Generally moths will lay only a few eggs per cola / plant because they don't want to overcrowd their young, though if allowed to hatch and grow they will quickly destroy your bud.
The eggs are white, tiny and round. They're fairly easy to spot, usually are stuck on a leaf, hair, calyx. Examine some buds closely and you'll find a few. I crush the ones I find with a tweezer.
