in your local area, is there an exterminator you could call? anyone who would know where the bugs are. what do they eat? what can they eat? i've heard of people feeding pinkies to spiders. could you set live mouse traps and breed them to use them as food? colorado is tough. do they eat other spiders? i made a dozen anoles sick by feeding them earwigs, i'm not sure spiders could eat them. somebody on youtube has to know how to make bug traps at low or no cost. if pressed, you could leave some crackers, or something else out, and see what shows up. if i think of any better ideas i'll let you know.
