This is what it boils down to boys and girls, IF you recommend some one a product that is poisonous to irradicate any form of parasite. make sure thats what its intended use is. otherwise Just because you have been doing it for 10 years does not make it safe. Bottom line.
Ive been smoking for 10 years, have not gotten sick yet. should i recommend you all start? of course not. will i eventually get sick from this? of course. But to base an opinion on a product and MISUSING IT and promising that its 100% safe based on the fact that you haven't had any problems yet is exactly the same thing. you know I can drive with my knee too.... pretty good to boot. does it make it a good practice?..... you know where im going with this people.
there should be no reason to promote the use of a pesticide in any way thats not recommended on the label period because you cannot guarantee the safety of the animal or the owner. If you want to do it fine, if they want to do it then really its there problem. but just because you have had said amount of time period between you and disaster is not a valid argument of the safety of the usage of said product thats not recommended by the manufacturer.
