Best insect product.

Hey guys, Ill be making a run to Lowes soon, and I need to get something for insects for my grow site, any suggestions?

Brand names and product name would be great

what insects do you have in your growspace.

Well I haven't seen any on my plants, but I know for a fact that their are crazy ass fire ants, its in a field area, surrounded by woods. I just wanted to get something before any kind of insects get into/around my plants.

neem oil.....

orange guard is a good defense
