They work good for the hotter months, but when the weather cools they don't seem to mess with itmuch.( I guess they needsomething extraon thosehot humid VA days)They are good for the camera though. I have one in my back yard and a few does visit it almost everyday especially after a rain storm. I have also seen a nice buck digg'n in it in mid-day before. I buy the Deer Co-cain.
I think they are worth it to see deer in the middle of the day.
