Carpenter Ant Treatments Nanaimo and Mid – Island
Signs of Carpenter Ant Activity
• Finding piles of “frass”, soft and fine shavings of wood inside your home or business.
• Finding winged ants in your home in late winter, early spring.
• Finding carpenter ants inside your home throughout winter or early spring.
• Rustling or crackling sounds inside walls, could indicate a potential nest site.
• Trails of carpenter ants entering and exiting the exterior of the structure, carrying food into the structure.
The first step in any successful ant management program is to correctly identify the species involved. While we have many species of Carpenter Ants in BC, two of them are of significant structural concern along the south coast.
Order: Hymenoptera Family: Formicidae Subfamily: Formicinae Genus: Camponotus Species: modoc
Description: Large, black head, black thorax, black abdomen, reddish legs, varied worker size (polymorphic). When viewed from the side (dorsal profile) the thorax is evenly rounded and smooth, and there is one node separating the thorax and abdomen.
Nest Size: Up to 50, 000
Monogyne: One queen per colony, located in parent nest. Can live for up to 25 years.
Colony Spatial Structure: Primarily polydomous, or multiple nest sites per colony. Parent colonies are often located in live or dead trees, tree stumps, wood piles, or landscape timbers. The queen, eggs, and early instar larvae are present in the parent colony. Numerous satellite colonies are constructed, where workers, later stage larvae and pupae are transported to for development. Rarely are parent colonies founded inside structures, as they require specific conditions for egg development. Rather, satellite colonies are common inside homes and other structures, where it is not uncommon to find multiple satellite nests, and potentially multiple nests from more than one colony. Satellite colonies can be constructed over 100 feet from the parent colony. C. modoc satellite nests do not contain functional queens, larvae and pupae are transported from the parent colony into the satellite nests. C. modoc has the potential to cause significant structural damage.
Order: Hymenoptera Family: Formicidae Subfamily: Formicinae Genus: Camponotus Species: vicinus
Description: Large, black head, red thorax, black abdomen, varied worker size (polymorphic). When viewed from the side (dorsal profile) the thorax is evenly rounded and smooth, and there is one node separating the thorax and abdomen.
Nest Size: Up to 100, 000
Polygyne: Multiple functioning queens per colony.
Colony Spatial Structure: Polydomous, or multiple nest sites per colony. C. vicinus colonies can become extremely large, and contain multiple queens, up to 40 in the parent colony. Like C. modoc, C. vicinus can construct multiple satellite nests, where mature larva, and pupa are transported to for development. Parent colonies are most often located outdoors, and satellite colonies are often found in insulated areas of crawlspaces, wall voids, attics, etc. While structural damage can still occur from C. vicinus, satellite nests are often found only in insulation. However, it is very common to find multiple nests, and have a very large number of ants infesting a structure and the surrounding areas.
Reducing moisture and rotten wood in and around the home is a necessary step in reducing carpenter ant activity. Remove or repair damaged areas of the structure, including: rotting wood, leaking roofs, blocked gutters, rotting decks, inadequate ventilation in attics and crawlspaces, leaking plumbing, soil contact with wood parts of the structure, old firewood, rotting fence posts and landscaping wood, rotting trees. Vegetation should not be touching the structure and should be trimmed away from the building. Soil lines should be reduce 4-6 inches below siding, exposing the foundation.
