Since silverfish love damp places, reducing the humidity in your home is a sure way to keep them out. Buy a dehumidifier and try to reduce the humidity in your home. If you don't want to use a dehumidifier, run the air conditioner or at least keep the fans on. If your house is full of dark, damp cracks and crevices, filling these is a good way to keep silverfish out. Buy some caulk and apply it along baseboards, inside cracks, and in holes in your wall or floor. This is particularly important to do in your kitchen, bathroom and basement. Keeping your floor clear of silverfish food may help keep their population down. Don't leave a pile of books on the floor, and clean up your dirty laundry before it sits there too long. In addition to these primary food sources, consider the following sources that may be a factor:   Cardboard boxes. Store your boxes on shelves instead of the floor, where they're more likely to get damp. Food containers. Keep your food in sealed plastic containers instead of boxes. Wallpaper. If you've got old wallpaper, consider replacing it with paint or new wallpaper. Old clothing. If you store your out-of-season clothing in your basement or a dark closet, consider placing it in plastic bags to keep the silverfish out. Vacuuming helps to keep their food sources down and sucks eggs out of the carpet and baseboards. Vacuum at least once a week. When necessary, you can dry out your carpets by sprinkling them with baking soda, leaving it for a few hours, then vacuuming it up. This dries out the eggs so you can suck them up.

TL;DR in Chinese:
给家里来一次防潮工作。 把蠹虫产卵的各种缝隙都给他填上。 清除家里的蠹虫食物来源。 彻底用吸尘器吸一遍房子。
