As with outdoor gardening, most bugs become a nuisance or a pest in one way or another. Hell, I even had too many ladybugs last year at harvest time and ended up finding dead ladybugs all over the place in some buds. Point is, you'll want to make sure no unwanted pests are running around on the plant, because eventually those trichomes will start acting like fly paper and it takes awhile to clean things up.
You can always put a layer of sand on top of the organic layer to help prevent things, however they tend to find a way underneath it and burrow into the root zone. A good tactic for that is to use diatemacious earth which will cut them into little pieces, yet it feels smooth to humans. Don't even think about putting sea sand on your plants though, the salt in there would kill your plants immediately. Clean play-box style sand can be used.
To sum up, yeah they are annoying lol.
