What is crawl space sanitization?

It is the decontamination step that follows physical cleanup. After contaminated insulation and debris are removed with HEPA extraction, the surfaces, framing, and soil are treated with antimicrobial products to neutralize bacteria and eliminate odor left by rodents. It turns a cleared space into a decontaminated one.

Why sanitize if the crawl space is already cleaned out?

Removing the bulk material does not neutralize the bacteria and residue left on surfaces and in the soil. Rodent droppings and urine coat the framing and soak into the ground, and cleanup alone leaves that behind. Sanitizing treats what removal cannot, which is why it completes the restoration.

Is sanitizing done with rodent proofing?

Usually yes. Sanitizing neutralizes the existing contamination, and rodent proofing seals the entry points so new rodents cannot return and foul the space again. Done together, they decontaminate the crawl space and keep it that way, rather than cleaning a space that stays open to reinfestation.
