For many Seattle residents, the first hint that something is changing comes on an evening walk along the ship canal or in their backyard garden: a sudden whine, the familiar bite on an ankle, or a swarm hovering near a backyard firepit.

Ticks in Washington State carry a wider range of organisms than many people realize.

Millipedes in the home are one of those odd, unsettling encounters that most people don’t expect until a rainy night sends a small army of tiny, many‑legged visitors across the basement floor. Despite their alarming appearance, millipedes are mostly harmless detritivores—creatures that feed on decaying plant material—and they become household pests for predictable reasons: moisture,…

Stink bugs — shield-shaped, slow-moving insects that release a characteristic foul odor when disturbed — are familiar to many gardeners and homeowners across North America. In the Pacific Northwest, attention has increasingly focused on one particular invader, the brown marmorated stink bug (Halyomorpha halys), because of its rapid expansion elsewhere on the continent, its habit…
