you have to be smart with these kinda things. pesticides and other chemicals can kill your plant, they are not very safe at all. try other things like bug tape and venus fly traps. just keep looking around, but my suggestion is to not use chemicals.
well depends if your growing indoors keep constant light on it, but if your growing outdoors you can put it in a place that gets very good sun. personaly i ike outdoors and thats what i do and its my 3rd year growing and never had any major issues
