Nope, perhaps you're onto something new -- did you once spill a Coke on your camera?
Nope, never spilled anything on or in it. It has been hanging on a tree for a year or more. The bug bomb seems to have worked. After I sprayed it I left it laying out on my driveway overnight with the front cover and the battery compartment cover open. Then after checking it several times a day for three days I couldn't find any more ants or sign of them.
(Luke 11:21 KJV) When a strong man armed keepeth his palace, his goods are in peace:
(Luke 22:36 KJV) Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
