Dampwood Termites tend to fly during the driest time of the year. This is usually from late July to August and even into September. Dampwood Termites need Damp Wood. As long as your structure has no Roof leaks, Plumbing leaks or Earthwood contacts then there is no need to worry about the dampwood termite. The female is not going to be able to succeed at rearing out eggs or instars without moisture.
When the reproductives fly they can get in a tiny vent hole that may be in a window frame or Roof or skylight. Pick them up with a vacuum cleaner. There is no need to use any toxic materials on Dampwood Termites. Remove the damp wood and the source of moisture from your structure.
Sometimes wood may be in contact with concrete. This may make the wood wet enough for dampwood termites to survive. Treat the wood by pouring or spraying Tim-bor into any crevice that may have dampwood termite reproductives escaping. The Tim-bor will pickle the wood so that termites will not be able to survive.
