Section 2-1-3-11-01-119.02 - Determining Active Infestations1. Determining the activity of Anobiidae (anobiid powder post) beetles in sub structures, attached garages or other outbuildings, and stored lumber. a. The presence of frass the color of fresh cut wood will be acceptable as evidence of an active infestation of the Anobiidae.b. The presence of holes alone or holes and dull colored frass will not be acceptable evidence of an active infestation of the Anobiidae except in such cases where live larvae and pupae are found in wood members. NOTE: Where numerous holes alone and/or dull colored frass are found in wood members, this should encourage the licensee or his representative(s) to check the upper living areas for infestation and to recheck the property during the optimum time for frass production by Anobiidae (March 15 to July 15). It should be pointed out that Anobiidae beetles usually infest products older than ten years and most infestations are confined to softwoods such as pine, whereas the Lyctidae only actively infest recently processed hardwoods such as domestic oak and pecan or foreign woods such as banak, meranti and obeche.c. Numerous other beetles may cause damage in the products that the Anobiidae and Lyctidae infest. Identification aids for these beetles are: (1) timber beetles and pin worms no frass in tunnels, tunnel walls stained darker than surrounding wood, no activity in products older than five years, and (2) bark beetles or bostrichids in softwoods holes few in number in or near bark, larval tunnels beneath bark scoring bark and wood, some of the frass is same color as inner bark.2. Determining the activity of powderpost beetles (Lyctidae) infestations is not required if infested products are less than ten years old. Otherwise, fresh frass and/or live larva or pupae in wood will be acceptable evidence of activity.3. Determining the activity of old house borer (Hylotrupes bajulus L.) infestations. a. The presence of adult beetles and oval exit holes with fresh sawdust like frass in southern pine, Douglas fir, or spruce wood will be evidence of an active infestation of the old house borer.b. The presence of live larvae or pupae in the above softwoods will be evidence of an active old house borer infestation, if the frass is sawdust like.c. NOTE: It should be pointed out that other long horned borers, flat headed borers, Siricid woodwasps, and marine borers sometimes damage softwood used in building construction. These other long horned borers produce loosely packed fibrous tobacco like frass, the flat headed borers make tunnels three times wider than high, whereas old house borer tunnels are less than three times wider than high, Siricids make perfectly circular exit holes, and marine borer excavations usually contain whitish calcium deposits but no frass.2 Miss.
