Keep your room clean,you shouldn't have bugs.
clean walls,clean floors,clean drain trays,ect.
if you want organic products there are quite a few.
neem oil(growshop,garden center)
oil of oregano(Heath store)
pure garlic juice(organic garlic cloves)
these can be mixed together if one won't work for your problem insect.
now this should go without saying,but I'm mentioning it........
never spray in flower,only veg.
controversial but I'm mentioning it,I grow my own organic tobacco,you can make a tea with the leaves or aact(compost tea)
i prefer Aztec tobacco it's got the highest nicotine content for pesticide.
another good one is organic habanero peppers boiled up,strain,mix in water spray.
can also be mixed with garlic,oregano oil,neem oil,or tobacco.
the best organic control is use your hands and kill everything,check every plant leaf.
but not everyone has time for that.
anyways again never spray in flower.
there are more organic pesticide's than these,but this is a good start
