Here is a good resource:
Wildlife Damage Management. I learned from
Snake-Removal.com that rodent urine is used in
snake traps. I also learned that snakes are drawn to moist areas, from -
NC State.
A
glue trap seems much too cruel. (although I did see advice on the internet to use vegetable oil or cooking spray to pour over a stuck snake, to dissolve the glue)
Look for a pest control company that can live trap a snake. You might get advice from your local animal control dept, game warden, fish & game biologist, or agriculture dept.
I like the funnel trap idea. Apparently snakes like to crawl beside walls or vertical surfaces, so traps are placed there. You do have to consider whether your snake is poisonous, because how are you going to deal with a captured live snake? There is a video on Youtube about building a funnel trap:
How to make a snake trap - YouTube
Here's an idea: Seal off all the entry points into your basement - with
door thresholds, weatherstripping, screens on vents/drains, expandable foam, etc. but leave one hole open where the snake can sneak out. Sprinkle a layer of flour on the outside at that last open exit. During the day turn off all the lights, (make it dark inside). A diurnal snake might move towards the light. During the night turn on all the lights in the basement. A nocturnal species might move towards the air movement coming from the hole. Check the flour; you might see the snake's tracks, and when you do, close off that last exit. If this doesn't work, at least you will have made your basement more vermin-proof.
To handle a live snake... If you aren't brave or foolish, buy a
Catch Pole or
Make your own catch pole. Snake tongs are available from
Tomahawk Traps
I'd be wary of staying at Papillon's house!
