Swarmers: On window sills or near an indoor light,
they usually indicate an infestation of the structure. If seen outdoors,
it is a warning
that they may attack a building nearby.
Wings: Swarmers discard their wings, which may be
found near window sills or in cobwebs.
Mud Tubes: Can be found between soil and a source of cellulose. They
may be seen going up columns, on foundation walls, or on pipes.
Wood Damage: Look for wood-to-soil contact or for moisture damage.
Tapping on the surface will give a dull, thudding sound. Probing
with an ice
pick will show galleries of tunnels which usually follow the
grain of the wood.
