Re: Frog decision
Most spiders that establish themselves in temperate domiciles are webbing species. Even is it is only a small funneled structure or series of connected shelters.
Small lizards, especially geckos tend to avoid webbing. Although lamellae structures are particulate repellent, it does not hold true for preventing webbing from tangling up in their feet. I know this because of the house geckos sometimes found in the cobs behind wood cages, on the floor.
Even larger animals like a polycrus pair ignored the fat brown false widows that stationed themselves in the uppermost corners of their environment, attracted to the cricket ecology.
It doesnt pull together in the picture people have or in selling points of vendors - the spider control aspect.
If a Mourning Gecko happens to catch a small spider in a viv it is by good fortune and not ecological design.
As for 'extra' insects and escapees, like little reptilian janitors, thats a theoretical wishful thought as well.
Frogs imposed to constant predatory hypervigilance that perhaps dull to a habituated desensitization in time - maybe? Who knows. But its not fair to the animals imo.
