As fall turns to winter and the weather gets wetter, you may be
spending less time in your garden, but mosquitoes will be making
themselves right at home. In San Mateo County, our weather never
gets cold enough to completely stop mosquitoes from reproducing,
even on our chilliest days. Items that can hold rainwater
for more than a few days – everything from wheelbarrows and
wagons to plant saucers and kids’ toys – can quickly become
habitat for thousands of mosquito larvae.
In some parts of the country, the weather is getting cooler and
tick season is winding down. Here in San Mateo County, however,
tick season is just beginning. Ticks become abundant shortly
after the first rain of the season, and continue questing through
the winter and spring. Adult western blacklegged ticks, our local
Lyme disease vector, are most abundant December through May,
while adult Pacific coast ticks and American dog ticks are most
abundant in the spring and early summer.
When the temperatures start to change and the nights become
colder, you may begin to notice six-legged visitors coming inside
your home. As we shutter our doors and windows to keep out the
cold, the humidity rises indoors. This elevated humidity
can attract insects and arthropods, including tiny insects called
Collembola, or springtails.
Eastern equine encephalitis virus, often termed EEEV or Triple-E,
has been making headlines lately in the United States. This
mosquito-borne virus can cause a sometimes-fatal brain infection.
With 31 cases and 9 deaths this year to date, this is the worst
outbreak of EEEV disease since the US began monitoring the
disease 15 years ago. While those numbers sound scary, EEEV
disease is relatively rare. An average of 7 human cases of
EEEV disease are diagnosed in the United States annually.

The District lab recently identified Turkestan cockroaches in
samples submitted by a county resident. The Turkestan
cockroach, Blatta lateralis, was first noticed in
California in 1978 around Sharpe Army Depot. Researchers believe
they were initially introduced to California from military
equipment returning from Asia or Afghanistan. In many parts of
the United States, the Turkestan cockroach is rapidly displacing
the oriental cockroach, Blatta orientalis.
Turkestan cockroaches produce considerably more offspring than do
the oriental cockroach.
The California Department of Public Health (CDPH) urges all
Californians to protect themselves from mosquito bites during
West Nile virus (WNV) season, which extends from now through

important to take every possible precaution to protect against
mosquito bites,” said State Public Health Officer and CDPH
Director Dr. Karen Smith.

You may have seen at some point in your life a giant cluster of
bees on a branch, tree or other structure usually in late spring
or early summer. These big clusters are menacing-looking, but
these buzzing masses are actually very safe to be around. They
are honeybees, and they are looking for a home.
