Can Rodents Really Chew Through Steel Wool?

Does Steel Wool Keep Mice Out—and Can Rats Chew Through It?

Steel wool for mice does work, but it's not quite as simple as stuffing it in a gap and calling it done. Mice and rats can technically chew through it, but the fine wires cut their gums, making it painful enough that they usually give up and go elsewhere. So does steel wool keep mice out? Yes—if it's packed tightly enough to fill the entire opening so there's no way to chew around the edges.

That said, regular steel wool has a couple of drawbacks. It rusts over time, which can leave stains and weaken the material. A better option is stainless steel wool or copper mesh, both of which hold up better outdoors and in damp areas. Products like XCluder are purpose-built for pest exclusion and outperform standard steel wool in most situations.

The most effective approach is to combine physical blocking with a bait station program. Stuffing gaps with steel or copper mesh stops new entry points, while baiting reduces the existing population. And if you're not sure where rodents are getting in, a professional inspection will find gaps you'd never spot on your own. Will rats chew through loosely packed steel wool? Almost certainly. But properly applied exclusion materials, combined with a control plan, give you real, lasting results.
