Deuteronomy 28:18, 38-40, 42

Your children will be cursed, as well as your crops; the calves of your herds and the lambs of your flocks will be cursed.

You will plant much seed in your field, but your harvest will be small, because locusts will eat the crop. You will plant vineyards and work hard in them, but you will not pick the grapes or drink the wine, because the worms will eat them. You will have olive trees in all your land, but you will not get any olive oil, because the olives will drop off the trees.

Locusts will destroy all your trees and crops.
