If silverfish and centipedes are making themselves at home, lowering your humidity is the most effective and chemical-free way to kick them out. If you’re serious about keeping silverfish and centipedes out, investing in a strong dehumidifier is one of the best moves you can make. Here’s how the models stack up and what to think about when choosing.

Frigidaire FFAD5033W1 (50-Pint): Great all-rounder. If you’ve got a large basement or a spacious, damp area, this model balances power, durability, and efficiency. You’ll see a quick drop in pests in those darker, damper corners.
hOmeLabs Energy Star 50-Pint: If noise is an issue (near bedrooms or frequently used living spaces), this one’s ideal. It offers almost the same moisture-removal power as the Frigidaire, but operates more quietly. A good choice if you want strong performance without the racket.
Waykar 80-Pint: Best pick if you have very large areas or extremely damp conditions. Its higher capacity helps keep humidity down even on bad days, which means fewer hiding spots and less chance for silverfish and centipedes to take hold. It costs more to run but gives a lot back in terms of comfort and pest control.

All of these dehumidifiers make a noticeable difference in pest prevention and indoor comfort.
