Report of an investigation of damage by wood ants in buildings in Sweden
1976 - IRG/WP 148
Wood ants in buildings occur everywhere in Sweden, particularly in maritime districts and in vicinity of larger lakes. The damage caused by Camponotus herculeanus does not differ from that caused by Camponotus ligniperda. The former occurs in all Sweden, the latter only in southern Sweden. The damage is to be found almost exclusively in dwelling houses (week-end cabins and "all-the-year round" hou...
An investigation concerning Camponotus spp. distribution and damage in buildings in Sweden

This is a report of an investigation by a Swedish insurance company on the occurrences of damage by Carpenter ants during 1974 to 1981. The distribution of damage in walls, roofs and floors of both permanent homes and summer-houses has been assessed.

Yeasts associated with the infrabuccal pocket and colonies of the carpenter ant Camponotus vicinus
2000 - IRG/WP 00-10335
Yeast associations in three colonies of Camponotus vicinus were examined in two different areas of western Oregon. We sampled the exo-cuticle, infrabuccal pocket contents of worker ants, interior galleries of each colony and detritus and soil in the area adjacent to the nest. Samples were plated on yeast-extract-malt-extract agar augmented with 1M hydrochloric acid and incubated at 25°C. Yeasts w...

Potential for controlling carpenter ants in utility poles with borates
2007 - IRG/WP 07-10623
Carpenter ants (genus Camponotus) are important scavengers and predators in the ecosystems in which they occur. Because they excavate and tunnel into wood, carpenter ants are considered structural pests in many parts of North America where they overlap with human activity. The excavation of extensive galleries in wood by carpenter ants can seriously compromise the physical properties of wood in ...
