spray bottle safe for worms? ( insecticide )
my original spray bottle broke due to years of use and we have a lot laying around the house the thing is they are old and most likely have pesticide/insecticides. the one i washed out with just water had some i know that for sure.
i was wondering would this be safe to use even though i rinsed it out? i'll be using it for my worms to spray the bedding down from time to time so i really don't want to kill them.
