I had a few anoles hanging around this spring, they were loving life for a while, warm temps and a few bugs. Then it got warm and the bugs headed outside, they started gettin real hungry and thin so I caught em and moved em outside. Kinda sucks they made for good entertainment. How effective? As a side note I have noticed a couple spiders now that they are gone and spiders are not as friendly or entertaining. Hmm, maybe I'll bring some back in and make sure to feed them once a week.
