What I will do is any time is see one first thing I will do is either make a cinnamon tea or even put a little cinnamon powder on the top soil they hate the smell and won't go in an lay larvae. It doesn't kill the adult so sticky traps are great. and to make the cinnamon tea you just take any where from 2-4 tbs of cinnamon powder and add it to hot/boiled water the water needs to be pretty hot. Add powder to hot water in a jug you can shake it up in then after shaking let sit and cool for 12-24 hrs then strain and you are left with a cinnamon smelling "Tea" you can spay it on the Tent, plants, outside tent pretty much anywhere you want and it smell likes cinnamon an deters them from going near there.👍 If they are really bad and already in the soil then Diotamacious Earth works great to kill anything trying to come up or into the soil it cuts them up as they try. Also another good easy preventative is to have some companion plants that have insecticide like properties like basil a lot of pest hate the smell of it so they stay away there is a bunch that can help look into it it pretty neat😊 Happy growing!!
