Long-horned wood-boring beetle

7420.     We found a few in our house. Petit-Rocher-Ouest, NB. Canada


Number 7420.   This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae). The only species in this family that will infest established dwellings is the old house borer, Hylotrupesbajulus, but your image is not clear enough to either confirm or reject that possibility .As the larvae of several species can take several years to complete their development, it is not at all uncommon for adult beetles to emerge indoors some time after a house has been built. Another possibility is emergence from firewood; see Long-horned wood-boring beetle detailed information .
