A few weeks ago I asked if anyone could tell me how to get rid of my crabs. Your outpouring of suggestions and sympathy was overwhelming. (sniff) Thank you.
Well, I think I'm making progress. Instead of trying all of the medications, chemicals and incendiary devices you guys suggested, I decided to go low-tech...I armed myself with a long dowel, snuck up on their holes, and if I saw legs, I harpooned the dowel into the hole. I have three confirmed crab-kills using this method. One of the crabs measured almost six inches across...I'm thinking about having that one mounted.
I've been avoiding using the cat-food-soaked-in-antifreeze method because a few of my neighbors have dogs, and I don't want them (the dogs) to dig up the poison bait and eat it.
I don't know how many more crabs there are, but my lawn is starting to look better after I filled in all the holes whose occupants met an untimely demise. bwahahaha.
