If the provider documented that the facet syndrome spanned both the lower thoracic region and upper lumbar region, i.e. T11 - L2, the diagnosis could be reported as M53.85. I would only code the M53.80 code if the provider documented facet syndrome without indication of any spinal region.
Wasps are actually beneficial insects for humans and the environment. They are one of the major natural scavengers, and they eat insects such as flies and caterpillars that are often considered pests to humans.
Spray at evening or dawn. The wasps or hornets will be mostly by the nest getting ready to sleep or wake up and won't be flying around. Night is also good since they will be sleeping, and therefore more docile, but you will have more trouble seeing and escaping if the nest does get aggressive.
