Just when you thought “rabid bat” season was over, two more showed up in the Santa Clarita Valley in time for Halloween.

After a lull in September, in October a Santa Clarita resident spotted a bat hanging from an eave of his or her home, and then lying on the ground. Later in the month in Newhall, a bat was found alive inside a home. Both were determined to have rabies.

They were the last two of 33 rabid bats identified in Los Angeles County so far in 2013. Of those 33, fourteen, or 42 percent, were found in the Santa Clarita Valley – even though the SCV sports just 3 percent of the human population.

Something is out of whack, and L.A. County Health Department officials are at loss to explain it. Nor can they explain why it’s been this way for the past four years, or why rabies cases are on the rise. Up to now, a “normal” year sees just 8 to 12 cases countywide, and they’ve been keeping track since the 1960s.

Bats are the most common carriers, but that’s not to say bats tend to have rabies. In fact, fewer than 1 percent of all bats do.

But if you see a bat flying around during the daytime, or hanging around the dog dish, or pestering the kids, or lying dead on the ground, it’s a pretty good indicator it has a health problem. Call Animal Control and report it.

And be sure to vaccinate the family pets; otherwise Fido or Fifi could be subject to a 6-month quarantine if he or she has been exposed.
