They are found along the wet environments of the Pacific coast of North America. Most are found in the states of California, Oregon, Washington, Idaho, Western Nevada and in southern British Columbia. Termites are well known to be destroyers of wood, and although the dampwood termites can cause some damage, they are not as notoriously known to cause as much damage to buildings as the drywood termites. They occasionally have been carried to other parts of the country through wood shipments, but have not been able to become established in these areas due to undesirable environmental conditions.
Zootermopsis angusticollis is a hemimetabolous, diploid species. Upon hatching from their egg, they are quite similar to adults except for their lack of genitalia. Their series of morphological instars allows them to increase in size until they reach their... Wikipedia →

With luck
About 10% of wildlife watchers report a Pacific Dampwood Termite sighting in Portland on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 507 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Pacific Dampwood Termite in Portland on a given day, against under 5% in October to July, the lowest months. Those are among Portland's driest months, with about 40 mm of rain a month against 250 mm in December.

Across all the parks we cover, that three-hour window holds the most Pacific Dampwood Termite sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 4 cities where we can rate Pacific Dampwood Termite sightings, Portland ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Seattle (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Pacific Dampwood Termite is recorded against all the insects logged in Portland (42 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
