I'm with you Briene, the petroleum jelly is the nasty joke we all face with breeding hissers. It's great for the adults because they have weight, but the nymphs race across it like there's no tomorrow. LOL
What I've done is taken weatherstrip seal tape..(it's a self adhesive foam) and gone around my 27 Qt locking lid sterilite tub and it actually does seal when you close it. Use the thinnest size seal...it's 3/8 wide x 5/16 thick and you get 2 ten ft rolls in a pack for little to nothing....I paid $1 at walmart for it on clearance.
I also have a 20 gal tank of hissers, and for that one I used the thicker foam and I believe I have got them on "lock-down" finally!
