Well, unfortunately, there's not awhole lot more that can be done, unless the authorities are willing to exterminate on a widescale basis in your area. There's obviously something in the area they like, and they'll most likely keep coming back. The only real options are to live with them, or to exterminate, and probably do so on a consistant and regular basis. And last I checked, long term exposure to even trace amounts of pesticides isn't a good thing.
Catching and selling them certainly isn't a bad idea. You'll probably turn out a nice tidy profit...which will probably end up being used to scorpion-proof your house and yard as best you can.
Just my two cents.
Yeah the catching and selling has been on my mind for a few days now because it could be a huge cash cow. Only problem is finding a way around the shipping rules. There has got to be some company out there that will not have a problem shipping the scorps. If there is an actual law against shipping them I need to find a loophole in it so I don't have to worry about getting in trouble for anything. If it was just 1 or 2 here or there I wouldn't care much but the amount that I want to be able to ship out might piss some people off if they find out about them.
