Can anyone tell me the episode name or number for an old episode of the X-Files possibly season 2 or 3?

Question

I remember certain details about the episode such as:

It had to do with these lumberjacks out at a small cabin in the woods that were found dead and spun up in some kind of webbing by these small insects that attacked in the dark only.

I remember that there was a generator that ran on gasoline that was keeping the lights on and it was running out of gas when Mulder was (I believe trapped in the cabin for some reason.)

It was a particularly creepy episode that I remember watching when I was younger and I would love to see it again. I would be VERY grateful for any info on this matter, or even a hint in the right direction.
