I'm wondering about these Mosquito Repellent Granules that I've seen on Amazon and Gardeners' Supply, which claims to be poison free and made of natural oils (lemongrass, mint and garlic oil). Has anybody used this? Do you think it would be safe for chickens if they curiously picked at it? It seems like it would be ok. I live on a lake AND next to a swamp in Florida and am desperate for some poison-free mosquito control for my chooks and for my family! My Flowtron & Stinger zappers don't work on these bugs. Dr. T's DT336 Mosquito Repelling Granules --on Amazon Same stuff @ Gardener's Supply -- Dr. T's DT336 Mosquito Repelling Granules Anybody used it or tried it or heard of anybody who has? thanks!
