Sevin was always one of those chemicals that seemed safe to use on anything, animals, vegies etc. Now it seems they are finding out it isn't as safe as they thought. Best thing to do would be google it and search these archives here, I know there are some good discussions on it here. I think it is being banned or talked about being banned for some applications, and it's killing the honeybees. I used the powder for a flea infestation once in my coop and run, and my chickens lived to a ripe old age.
