Whats the name of this movie?

All i remember is that it took place in a weird desert place where there were trailers and these little boys were playing i think and i think they find a hole or one boy falls in one and its sandy and there's a skeleton and the boy is scared and his friends come and they laugh at him but something comes at him like bugs i think and they crawl in his skin go underneath his skin actually all the way up to his eyes in his veins and his eyes turn solid black. after that i think he attacks the boys or they just run. all i remember after that is that the government came built some things over the hole searched in it and the same thing happened to a couple of people with the bugs and the eyes and they became dangerous
