The answer to 'how to get rid of silverfish' is to use a combination of prevention and targeted treatment. Silverfish are nocturnal pests that thrive in moist, humid environments and feed on starchy materials like paper, clothing, and glue. To get rid of them, you'll need to address the root causes and eliminate their food sources and hiding spots.
Start by reducing moisture and humidity in your home by fixing any leaks, improving ventilation, and using a dehumidifier if needed. Seal cracks and crevices where silverfish can enter and hide, and eliminate their food sources by storing dry goods in airtight containers. You can also try setting out boric acid or diatomaceous earth, which can kill silverfish on contact. If the infestation persists, you may need to use an insecticide spray or bait, but be sure to follow the instructions carefully. For severe or recurring issues, it's best to call in a professional pest control technician who can properly identify the problem and implement a comprehensive treatment plan.
