I have a purpose made device for that job. It’s a clear plastic cone with a hollow handle at the point. Half the open end is closed off. Inside there is a semicircular ‘door’ with it’s own handle that sits inside the hollow one.
You place it over the creature that’s getting evicted, then rotate the inner handle so the door rotates over the opening, sealing it (taking care not to trap any legs).
Then go outside and reverse the process to release it.
Personally I don’t mind spiders and would rather have them around than the pests they eat, but wifey is incredibly arachnophobic, so they have to go.
