I have a rather hands-off approach to all critters with more than 4 legs.
If I see something that doesn't belong...I usually scream like a little girl until DH comes by and removes it (grumbling and complaining, and rolling his eyes the whole time). Depending on the season, it either goes out the front door or down the terlet. Strange to think I was a biologist. But then....fish don't have more than 4 legs. I can handle anything....as long as it doesn't have more than 4 legs!
