a lot of people do the poison treatment because its easy, the natural ones take time and effort. those companies are making billions of dollars per year one company made 825 million dollars last year alone, they are not in it for the welfare of your pet, there in it for the money. once enough reports come in about sick or dying pets they change the formula and the name. and start over, these are poison regulated by the epa. environmental protection agency. they also pay for a lot of the veterinary schooling and throw huge incentives to push the products. look up the studies they do, on dogs and expose them to high doses of the stuff very sad, we lived with ticks and flea long before these products came out. there is definitely way too many unnecessary vaccines out there, that do more harm than good all of which kill you dogs immune system, which make them more susceptible to Lyme etc.. we are bad pet owners if we don’t use the products they scare you to death, me included. putting poison on the pet does not protect the person probably creates more exposure, seeing the tick has to suck enough poison from the pet to drop off in your house and then climb on you that is scary
