Termite alert that uses gravity to cause a color changing chain reaction

摘要

A termite alert device for placement within an area subject to infestation by termites and the like, particularly at constructed walls, wooden floors, concrete, patios, pool deck, and other hard surfaces. The termite alert device housing includes a substantially clear viewing port beneath which is positioned a signal element which may be colored in contrast the housing interior. The signal element is supported by bait subject to ingestion by termites. As bait is consumed the element drops away in a mechanical chain reaction presenting an alerting appearance change established by a change in visualization as the element increases distance from the port. The alert device may be substantially vertical with cylindrical or other suitably-shaped bait material and signal element. Alternatively it could arch outwardly toward a side wall, with signal elements comprising a series of colored balls falling along the arch as they collapse downwardly in a mechanical chain reaction.
