Termite infestations typically remain untreated until major damage becomes obvious. Homes in San Diego constructed primarily of wood are not the only structures threatened by termite activity. Homes made from other materials can host termite infestations, as these insects are capable of traveling through plaster, metal siding and more. After termites break through, they feed on floors, ceilings and furniture within the home. Most of the damage termites cause is not covered by standard homeowner insurance policies.Common signs of termite damage include sagging floors and ceilings, traces of sawdust at the base of beams, piles of wings or winged termites and areas that seem to be slightly water damaged at a casual glance. Contrary to popular belief, termites are not partial to aging wooden structures. In fact termites have been known to begin infestation within four days of completed construction.
