How would they know they are too big? Maybe call the manager? Scrap the mealworms, those are good for nothing. Roaches, superworms, silkworms, crickets, phoenix worms are all good.
Thought id share a cheap easy way to hang your pothos without damaging your screen.. Well, too much atleast. I went to the hardware store and got a 1-1/4x48 wooden dowel, cut it down to 24 inches and screwed a small hook into it.
You are misting right? Get a mistking, its an automatic mister. And drippers are easy to make, get any size tub, put a hole in it, go to your local hardware store, and get a little needle valve and some hose to put on the end of it. There you go, homemade dripper.
I stated it a little wrong in my post, a little bit of dirt is fine, but if they miss alot, or are just curious and seem to enjoy the taste of dirt and eat to much, then it gets impacted.
