What Is Cellulose Debris (in a pest or termite report)?
Usually cellulose debris means that there are scraps of wood, sawdust, or bits of wood (possibly paper). It’s any kind of material made of wood. Most often, cellulose debris is mentioned as found in the crawl space of a home. Sometimes it’s infected (meaning there is a wood destroying organism such as termites present), other times it’s simply an invitation for “wood borers” such as termites to come and feast on the wood members that are laid out as a buffet for them.
In our Silicon Valley area, pest reports are normally “separated” into Section 1 and Section 2 findings. If the cellulose debris is called out as Section 1, that means that there’s an infestation of termites or other wood-destroying organisms present. If it’s Section 2, that means that it’s not yet infected but is an invitation to trouble.
Pest control operators will suggest that cellulose debris be removed so that termites and other wood eating oranisms aren’t attracted to the crawl space or other areas of the home. It’s a nuisance to get rid of it, but much better to prevent a problem upfront than to wait and have to solve it later.
