The exterior shots of the crop fields in the episodes were filmed in ginseng fields, which writer Frank Spotnitz felt had an "otherworldly" quality to them. These fields were located near the city of Kamloops, which is approximately a three-and-a-half-hour drive from Vancouver; a location from which the production had rarely strayed during its first five seasons. The hair, makeup and wardrobe truck ended up getting lost while driving there. A fiberglass composite lattice used by the aircraft industry was used to create the honeycombs through which the alien bounty hunter chases Mulder.
