Urine/Feces in Crawlspaces

Urine and feces odor in crawlspaces can be caused by any number of animals including cats, rats, mice and even skunks. This is a common problem our service division treats.

We use high pressure spray equipment similar to an airless paint spraying machine. The long hose gives much greater freedom to move around in the crawlspace while the high pressure produces a very small droplet which has better coverage and penetration. We use 515 spray tips on our spray machines.

An alternative would be to use a pump-up type garden sprayer. Unfortunately, these types of sprayers are difficult to use in shallow crawlspaces.

Application rates are as follows:
1. If the crawlspace is covered with a plastic vapor barrier, 200 sf per gallon of SCOE 10X ready-to-use is the usual application rate.
2. For a dirt floor crawlspace, 100 sf per gallon of SCOE 10X ready-to-use is the usual application rate.

Rule of thumb for SCOE 10X application rate: for every part urine deposited over time, an equal part SCOE 10X will need to be applied to that location.

For personal safety, always wear a paper mask and goggles or a full face respirator when high pressure spraying SCOE 10X.
