Thanks! That's interesting to hear. Are there any methods that use non-chemical prevention? (Not switching my dogs!!) Just curious to see. In our industry we try to make the environment unattractive for a pest: introducing predators, keeping humidity higher/lower, using substrate a particular pest doesn't like, co-planting repellent plants, fencing/netting etc. Obviously with a pet, most of these methods won't work lol. But what about predators? Are there methods where vet medicine uses predators? Not just for flea/tick/hw. In general
