Nesticodes is a monotypic genus of comb-footed spiders containing only the red house spider [Nesticodes rufipes (Lucas, 1846)].

[1] It was first described by Allan Frost Archer in 1950,[2] and has a pantropical distribution due to ship and air travel.

[3] Nesticodes rufipes is a small red-bodied spider, venomous, but not harmful to humans.

[3] They can be extremely common inside homes, building webs in dark corners and under furniture.

They have been observed preying on insects such as mosquitoes,[4] flies,[5] and ants.
