Trigger, 1 bag of fertilizer (high ammonia content) place on or under if ya can. Soak fertilizer with diesel fuel. We always used a blasting cap & triggered it with the battery on the little ferguson, loooonnng wires. It would probably be better to just use tannerite, easier to get & just as effective. Good luck,let us know how ya make out. GWPGUY. 🐾👣🇨🇦
