I purchased a 50 lb. bag of diatomaceous earth several years ago at a local feed store for just over $21. It is especially suited for hard-shell pests. Just be sure it is formulated for general use and NOT for swimming pools. Do an Internet search to get info on DE, but call your local feed stores for the best prices and immediate access for using to get rid of the crickets. DE is very safe to use around animals–just be sure to cover your mouth and nose with a paper dust mask when applying the material.
