False Cinch Bugs are fast breeders and eggs take only a few days to hatch. Nymphs mature into reproducing adults in less than a month. This means many generations of bugs can live at the same time, feeding in the same field. Mid-summer sees populations at their largest size, which is when many crops are reaching peak growth for harvest. They overwinter in both life stages, taking nutrition from cold-weather crops and wild plants like sages. Look for adults in the cooler parts of the day like dawn and dusk. The hot afternoon sun drives them to the ground for shade cover. In dry, hot spells during the summer, clusters may see cooler temperatures inside buildings. They are not dangerous to people: they don't bite or destroy interior dwellings. They are a nuisance, but usually a short-lived one, lasting only a week or so indoors, but removing indoor populations using a vacuum is recommended over pesticide use.
