I found that using the plastic netting from a shower scroungie(?) work really well for use in the drains to keep anoles out of lanai and birdcage, we have not had one on over a year. I take an old (or new) scroungie and take it apart (cut the tie in the center). You end up with a couple yards of plastic screening. I then take this ant stuff into openings. This allows air, water, etc to get in and out, but keeps small crawlers (aka anoles) out.
Hope this helps.
