I've had them spawn 3 times in the same spot and it was close enough to me where I could kite them to my turrets. I've gone a little deeper into their tunnels once and still managed great. I dunno how you guys are having so much trouble just requires a little kiting.
I wonder if you could make a compound and let them infest all the surrounding area and use them as a defense from raids.
