Pest ?

[JD466US]

I have some White Widow clones that I have growing outdoors(in dirt,in pots) for about a month that I want to bring in and put in my grow closet. Now I don't want to bring in anything with them since normally I use a DWC Hydro set up in there, but decided that I wanted to try a dirt grow under the 400w hps light and see the difference in my grows.I am looking for suggestions on what I can use on the girls that won't hurt them but that will kill any critters that might be living on them.

Thanks,
JD
