The answer to 'how to kill silverfish' is to use a combination of prevention, traps, and targeted insecticide treatments. Silverfish are small, wingless insects that feed on starches, sugars, and cellulose. They can be difficult to eliminate, but with the right approach, you can get rid of them effectively.
Start by identifying and eliminating their food sources and hiding places. Silverfish thrive in damp, dark areas like bathrooms, basements, and attics. Reduce moisture levels, seal cracks and crevices, and remove any paper, cardboard, or other organic materials they may be feeding on. You can also use sticky traps or bait traps to capture them. For heavy infestations, apply a targeted insecticide treatment in areas where you've seen them. Be sure to follow the product instructions carefully and take appropriate safety precautions.
