Silverfish or firebrats

6701.      I live in Delta, BC and find these pests mainly in my bathroom. Occasionally, I find them in my kitchen and laundry room. They vary in size from about 1/4 inch to 1 inch. They are dark in color and move very fast. They have 8 legs, 3 feelers in front and 2 feelers in back. What are they? Are they harmful? How do I get rid of them? Darlene Balcome, Delta, BC
