Hey you can do as Northnut mentioned and that will kill them. Or if you want to a simple way to try to get rid of them before you go an little harsher method you can make a cinnamon spray by adding 2-4 Tbs of cinnamon powder into hot water it best to get the water almost to a boil if not boiling them have the powder already in another container/jug that you will be able to shake up with the hot water in it. then after you shake it let it sit for 12-24 hours, strain then spray the bugs hate the smell of it and it may kill them as well. I use it anytime I see a sign of any type of bug. Happy Growing!!
