These contraptions are brilliant!
OP I have a phobia too, although I'm not quite as bad as I used to be. Taping up a door may sound bonkers to anyone who doesn't have our phobia but I totally get it. Methods I've used before include:
Getting my neighbour round to remove the beast.
Home made scoop:
#1 an empty litre juice carton with the end cut off to form a scoop shape and the other end stabbed onto a long handled meat fork.
#2 a plastic flower pot sellotaped securely to the end of a broom handle. This one was used to remove a monster from the bath; bathroom window opened first, as wide as it would go, then scoop, lift and chuck in one smooth motion. And when I say chuck I do indeed mean flower pot, broom and all right into the garden.
Trapping the horror under a glass, drawing arrows on several pieces of paper and arranging them to form a path leading from the back door into the lounge and ending with a note by the glass saying Spider Under Here. Got up in the morning to find the arrows leading from the bottom of the stairs to the glass and a note from my DM saying Spider All Gone.
These days I use one of the thingies with bristles above if I'm feeling brave enough to deal with it myself (I prefer these because you can still maintain some distance between you and the abomination. The plastic ones with a sliding trapdoor are ok if the thing is on a wall and you can rotate the contraption to slide the trapdoor shut, but if Boris is on the floor you have to manually slide the door closed which means nearly touching the damned spider. NO!) or get DH or DDog in on the act.
