I have one and it works as advertised. Have had no problems with mosquitoes
laying eggs.in stagnent bird bath water. The wiggler does seem to attract
the numerous finches that use a nearby feeder.

One set of fresh batteries lasted the entire season (April thru October)
last year and it appears the same will be true this year. BTW, I bring my
wiggler in for the winter.

hi,

i have seen these devices advertised. they supposedley lightly agitate the
water in birdbaths thus preventing mosquitoes from laying eggs and also
attracting birds through the motion of the water.

i did a group search and while they are mentioned on occasion, i can't
find
anything where someone says, "i have one and they are good, bad or
indiferent."

does anybody actually have one of these devices in their birdbath that
would
care to elaborate on it?

thanks,

mike
