may migrate from one part of a structure to another depending on
temperature and moisture fluctuations. They will move away from
extreme heat. During the day, they may be in the attic and as the
attic heats up, during the summer, they may move towards the eaves
or down the inside structure walls. In the summer they may be eating
in a wooden patio deck, and then as the winter rains come, it will
force them out of the deck and into structure walls. As the rains
stop, they would move back out into the patio area unless the food
source that they found inside the structure is more to their liking.
Several times each year drywood
termites will SWARM
to form new colonies. They will grow wings and turn a deep reddish
brown. When the conditions are just right, usually in late summer,
as much as half of the colony may fly off in search of a new food
source while the other half of the colony will remain where they
are. This is called a SWARM. They land and loose their wings to
start the new colony which could be in a window sill, patio deck,
a wooden roof or eaves, trellises, walkways, external electrical
meter box, or other weak points in a structure.
do we treat them?
