are they fruit flies, fungus gnats, ect? I have fruit flies, brought in by my dunb ass wife who buys OUTdoor fvcking soil for her INdoor plants. ive been using captian jacks spinosad 1x every 2 weeks when watering. shit stops them dead, the 2nd treatment stops any newly hatched buggers laid by the adults who were killed by the 1st treatment. capt jacks spinosad is good for quite a number of pests.
