Hogna lenta produces three distinct burrow architectures.
Open burrows are used as temporary to permanent dwellings, nests, and sites for prey ambush. Components of burrows include one surface opening, a single shaft or tunnel, and rarely a circular to ovoid chamber. Burrows are vertical (80°–90°) or subvertical (60°–75°) in orientation. Shafts, tunnels, and chambers are circular to elliptical in cross section; chambers are up to two times the size of the shafts and tunnels. Shafts and tunnels are straight and generally have a consistent width along their length. Shaft and tunnel walls are either smooth with multiple scratch marks along their length when they have a thick silk lining or irregular when they have no silk lining.
