It’s Termite Season

If you take walks in the early morning or evening you may have recently seen clouds of fluttering insects rising from the ground. They don’t fly well, but when backlit by the sun, it makes you think of quiet days sitting by a lake in the morning mist.

If only they weren’t termites.

New Larviciding Methods at Mills Field

In September and October, the district was having trouble penetrating vegetation with a granular larvicide in Mills Field (San Bruno) that was breeding mosquitoes. Staff decided to set up a sprayer that would put out a high volume of liquid larvicide that would push through the cattails and into the water. Mills Field is usually a helicopter treatment site with 32 acres of mosquito breeding habitat. This year, most of the water had dried up, leaving a 5-acre ditch which did not warrant the cost of a helicopter treatment.

A Short History of Malaria in California

Many people may not know that there was a time, not long ago, when malaria was more than a disease you only worried about when traveling. Malaria is a mosquito-borne disease resulting from a parasite that causes fever, chills and flu-like symptoms that can progress to liver and kidney failure, or even coma and death in the worst cases. There are four protozoa that can cause the disease: Plasmodium falciparum, P. malariae, P. ovale and P. vivax.  All four of these parasites are carried by mosquitoes in the genus Anopheles.

A Pest in the Pantry

Beaches are popular among San Mateo County residents this summer, including our local bees. District staff responded to a request in June to identify bees nesting on a beach in Pacifica that were flying in and out of small holes in the sand.

Mosquito Spotlight: Orthopodomyia signifera

The District works to control mosquitoes in our county because they are disease vectors and aggressive biting pests. However, there are several mosquito species that are not known to bite people. One of these infrequently-encountered mosquitoes is called Orthopodomyia signifera. It breeds in the holes of trees that hold water year-round and feeds exclusively on birds.

Seasonal Catchbasin Program Continues

Our seasonal catch basin program has been up and running since mid-April. Our first seasonal employee started on April 20th. Currently we have six seasonal catch basin drivers working from East Palo Alto to Daly City. On an average day, one driver can treat anywhere between 400 and 800 catch basins. Basins are treated with BVA-2, a material similar to mineral oil which coats the surface of the water and prevents mosquito larvae in the water from breathing. The material dissipates after a few days. In May, our staff sprayed 37,821 catch basins.

Staff Adapt to Coronavirus Safety Precautions

District staff has been doing a great job adapting to the ever-changing coronavirus guidelines. Currently our vector control technicians are showing up to work with a fresh uniform on each day, getting in their work trucks at 8 am, and heading out to the field. We have a staff meeting online twice a week using the Microsoft Teams app to help coordinate work for the week. This has been a great feature because gives us the ability to connect with all of our staff at one time in a virtual meeting room.

Local Bees and Wasps: A Case of Mistaken Identity

The Asian giant hornet may be all over the news, but residents of San Mateo County are far more likely to encounter our local species of bees and wasps.  As the weather warms up, these insects become more active and more numerous in yards.  Although capable of stinging, most species are non-aggressive, and only sting defensively when their nests are threatened.
