Get yourself a bearded dragon and your spiders will meet their maker.
Having trouble with those creepy, crawly eight-legged arachnoid freaks? Well, just open up the door and let your friendly neighborhood bearded dragon lizard in.
Here's one that's more than willing to make lunch out of every one he finds.
Well, that was educational. Can 'beardies' climb the walls to get at 'em too? I personally like spiders because they eat so many of the other things that try to... eat us!
If only we could add a "bearded dragon eats spider" rule to rock-paper-scissors.
