Removing B. Anthracis spores is tricky due to their ability to withstand extremely harsh conditions. According to the CDC and a number of primary sources, a 1/10 solution of bleach can be used to kill the spores, but it must remain on surfaces for at least 30 minutes. Whole-structure fumigation with methyl-bromide is also effective, but is toxic itself and requires sealing the structure from the environment.
