Just a guess, but i would go to wallyworld and buy some scented mothtablets and you can get them in a lialoc fragerence, Check spelling, none the less, it's what we use when the rv is in storage and we never have small gritters about at all, $1.00 a box, takes about three boxes to cover the whole Rv from top to bottom and front to back. Good Luck!
