Midges Annoy But Don’t Bite

During spring, the District sometimes gets reports of flying insect swarms. These insects look a lot like mosquitoes, but are actually a different type of insect: midges.

The good news is that these midges don’t bite, don’t carry any diseases, and are harmless to humans. The bad news is that, as many of you have already found out, they can be really annoying! They’re often seen in large swarms, and may gather around outdoor lights or on the sides of buildings.

Rainy Weather and Mosquitoes

Do wet or dry years create more mosquito problems?  One might immediately assume wet years because mosquitoes need water to breed.  On the other hand, droughts create pools and puddles in water bodies like rivers and streams that would otherwise be flowing too strongly for mosquitoes to utilize.  The reality is both weather patterns cause different types of mosquito control challenges.

Tularemia, rabbit or deerfly fever, is a relatively rare bacterial disease transmitted to humans and animals by the bite of ticks. It is much less common that Lyme disease in California and is primarily transmitted by the American dog tick (Dermacentor variablis) and possibly by the Pacific Coast tick (Dermacentor occidentalis).

Tick Surveillance
2016-2017 Winter Season

The District laboratory is taking advantage of breaks in rainy weather to collect ticks from parks and open space areas in San Mateo County.   Ticks are collected by dragging a tick flag – a large white piece of flannel attached to a wooden rod – over the vegetation alongside trails.  The main target species of tick is Ixodes pacificus, the western black-legged tick, which vectors Lyme disease, Borrelia miyamotoi infection, and anaplasmosis.  The ticks collected will be tested for the presence of bacteria that cause these diseases.  The Ixodes pacificus ticks are in

Bugs That Bug You: Western Conifer Seed Bug

Today a resident brought in an insect she’d found on her live Christmas tree. She was concerned that it might be a kissing bug, the insect vector of Chagas disease.

Fortunately, the specimen was not a kissing bug. It was a western conifer seed bug, a minor tree pest to conifers – like Christmas trees! These bugs aren’t harmful to humans, and can be gently relocated outside if found indoors.
