Thank you so much indeed for all for the precious advices for geckos! I really appreciate so kindly reactions in this group!
I will talk to the library staff and make some prototypes with door and hardware cloth. Unfortunately when I fount them, the geckos are already without life....... Its good to know the use of vegetable oil. Hoping to not to see them again in the trap, anyhow I will keep oil with me. Thanks to all!
