TNT is strikingly effective and environmentally friendly. It won’t hurt wild animals, aquatic animals, birds or their environments. TNT is helpful to you preventing tick-borne diseases by ridding your pets, yourself, and your environment of pests. Just as importantly, TNT can be applied bi weekly, sometimes even less often – making it significantly more cost effective than competing products. In over 2 decades of field use, TNT – Tick Natural Terminator – has shown no side-effects when used as directed.
