What Are Those Strange Insects? Western Conifer Seed Bug! October 21, 2009Posted by bsciencecenter in Uncategorized.
The large, brown bug, found entering homes is the Western Conifer Seed Bug. This species, first described in California in 1910, has quickly moved eastward. In 1956 the WCSB was reported in Iowa and in1990 several were found in New York State.
In the fall, the Western Conifer Seed Bug enters homes through cracks and crevices searching for protection from cold temperatures. In the spring they return to the outdoors to feed on the developing seeds and flowers of coniferous trees, including: white pine, red pine, hemlock, and spruce. The female lays rows of eggs on the needles and the eggs hatch in about ten days. The nymphs, which feed on the scales of the cones and occasionally the needles, pass through five stages of development and reach adulthood by late August. It is around this time that the bugs begin their search for over-wintering sites.
Are they harmful?
To humans, NO! They do not bite, sting or eat wood. They are more of an annoying pest as they sound similar to a bumble bee when flying by your ear.
How do you remove them?
Call Ms. Pavlicek to remove them! Just kidding! You can prevent the entry of these bugs in buildings by calking openings around windows, doors, and chimneys, repair damaged window screens, and screen attic and wall vents. The bugs can be easily captured and returned to the outdoors or vacumed into a bag and disposed of. The use of pesticides is not recommended.
