Warming Climate Spreading Skeeters, Ticks, & their Diseases

Climate change promotes the spread of mosquito and tick-borne viruses,

Threat Levels

We already knew this, that warming weather and shortening Winters were allowing the spead of dangerous invasive mosquito species, as we've watched a whole series of new tropical skeeters and their diseases march North across California over the past twenty-plus years. But, keeping up with the latest threats is a good way to keep our anti-mosquito systems up to date and effective.

Field Protection

For me this is a bit of a problem, 'cause I would prefer to wear as little clothing as I can get away with while hiking, which makes me a big, juicy target. Not wearing protective clothing during Spring and the early wet part of Summer is just crazy.

I can get away with chemical protection only, later in the season, but the early season requires clothing to cover as much as possible, and 100% DEET for the rest.

Travel Measures against mosquitoes



Mosquito Research Highlights

"Spurred on by climate change, international travel and international trade, disease-bearing insects are spreading to ever-wider parts of the world."

"This means that more humans are exposed to viral infections such as Dengue fever, Chikungunya, Zika, West Nile fever, Yellow fever and Tick-borne encephalitis."

"Aedes mosquitoes spread several arboviruses, including  Dengue, Chikungunya, Zika, West Nile and Yellow fever viruses."



Skeeter Scorecard

In California we've already absorbed two nasty tropical mosquito species, brought on the wings of rising temperatures: Asian tiger mosquito, Aedes albopictus, & Yellow fever mosquito, Aedes aegypti.

Both these skeeters spread a wide variety of diseases we've never seen in California, until now...

Nonetheless, we've seen a steady progression of invasive skeeters with the rising avergage temps in California, beginning with West Nile in 1999. It looks like we are approaching the beginning-point of next experiencing a progression of the diseases they carry.
