Used to have one of the ones which has a clear pyramid on a stick. The sliding door didn't usually work by itself, and the creature's legs would get stuck in it. And it wasn't very big.
Looking for a better one on Amazon and Ebay. I can see two other main types.
One has plastic bristles, and I'm not very confident they'd keep a large spider secure if you have to put the catcher down to unlock a door to put the thing outside.
The others have vacuum action. Can' t tell how efficient this is, if the spiders can get out if you take too long to put them outside, or if the end is big enough to put over spiders with long legs.
Any recommendations or experiences with these?
