Wingless, scaly insect that thrives in humidity. Destroys paper, fabric, and stored food.

BC's most venomous spider. Found in dark, dry undisturbed spaces — garages, woodpiles, crawl spaces.

Fast-moving funnel-web spider. Commonly found at ground level in basements and under foundations.

The dominant flea species in BC. Infests homes via pets and wildlife. Eggs survive in carpet for months.
