The spiders I find in the house, I usual offer my hand or a piece of paper and once onboard, carry them out. This is not often I come across them. Same for the anoles that make it in, I have no clue how. I have to catch them and sometimes the spiders. The anoles even get a drink of water before I turn them loose. My attitude regarding ants is extermination, as so any masses of bugs who would be treated with utmost hostility.
