You may think the worst you need to worry about
raccoons is them getting into your garbage cans but don’t be
fooled! These masked bandits also carry a potentially deadly worm
called the raccoon roundworm or Baylisascaris procyonis.
Round worms live out most of their lives in the raccoon’s
digestive tract. The eggs are eaten when the babies are suckling
and carried throughout the life of the raccoon. The male and
female roundworms grow, meet, mate, and lay eggs in the raccoon’s
intestines and their eggs are ejected from the body in feces,
ready to find a new host.
The recent king tide, in combination with warm weather, has
allowed an unexpectedly large number of summer salt marsh
mosquitoes (Aedes dorsalis) to emerge in areas of the
bay adjacent to Foster City, San Mateo, and Redwood Shores. These
mosquitoes bite during the day and can be a major nuisance,
but fortunately are not a major vector of mosquito-borne disease.
The 2016-17 San Mateo County Civil Grand Jury recently released a
report titled ‘Can We See You Now? San Mateo County’s Independent
Special Districts Website Transparency Update’ discussing San
Mateo County special districts’ progress toward achieving the
transparency standards set forth by the California Special
Districts Association (CSDA) and the Special District Leadership
The California Department of Public Health (CDPH) reminds
individuals to take precautions when entering cabins, trailers
and other buildings that may be infested with rodents after the
recent diagnosis of hantavirus pulmonary syndrome (HPS) in a
Northern California man.
Mites are probably one of the most common insects on the earth
and the vast majority of them have not been described yet. While
the majority of them are harmless to humans and even helpful to
us, there are several that are found in San Mateo County that can
be a right nuisance. Most of these species are unable to invade
your home without their host (usually rats or wild birds) but
once there, they may bite humans if they reach a large population
size or their host dies. Below are some of the most common biting
mites in San Mateo County.
Did you know that there are more stinging insects than just wasps
and honey bees? Stinging insects are grouped into the family
Hymenoptera and are distinguished by having 2 sets of wings, a
cinched “wasp waist,” and an ovipositor that has been modified
into a stinger. That is about where the comparisons end however.
The following article covers the incredible diversity of stinging
insects and even points out a couple of the “wanna-bees” that
have evolved to mimic their much more aggressive cousins.
The California Department of Public Health (CDPH) urges all
Californians to eliminate standing water around their homes and
businesses to help reduce mosquito populations in an effort to
prevent Zika and West Nile virus infections.
