Important Information Regarding Mosquitos

August 22, 2019

To District Parents and Guardians,


The Cajon Valley Union School District as well as San Diego County in general has recently experienced a
sharp increase in mosquito populations and bites. The County of San Diego has provided good information
regarding recent invasions by three new species of mosquitoes into our area. This information explains their
behaviors as well as measures for personal protection and prevention of habitats for breeding. This can be
found at: https://www.sandiegocounty.gov/content/sdc/deh/pests/aedes.html


From our previous experiences with mosquitoes native to our area, we expect to see their activity only during
dusk and dawn hours. Rarely, if ever, do we see them during daytime hours. Unfortunately, these new
mosquitoes are most active during the daytime hours. They routinely fly low to the ground, are attracted to
humans and frequently bite the legs.


Protective measures that can be taken to prevent bites include wearing long sleeves and pants or use of an
appropriate insect repellant. Applications of appropriate repellants have proven to be both safe and effective.
If you choose to use these products to protect your student, please ensure that they are applied at home,
before school, and not brought to class. Information from the Centers for Disease Control and Prevention on
the use of these products can be found at: https://www.cdc.gov/zika/prevention/prevent-mosquito-bites.html


The District has been in contact with the County of San Diego Vector Control Department. They worked with
us to inspect school sites and we continue to take the necessary steps to ensure attractive breeding grounds
for these mosquitoes do not exist on our school sites. Preventing stagnant water from ponding, frequent
mowing of grass and irrigation maintenance are steps we are taking. If you notice areas on your school
campus that you feel need attention, please report it to the school office. We also please ask that you take
similar precautions around your homes as mosquitoes do not necessarily just stay at the location of breeding
and can cross property lines. By working together, we can help reduce the impact to our community that we
are currently experiencing.


If you have any questions, please do not hesitate to contact me via e-mail or phone.

 

 

Sincerely,

Scott Buxbaum
Assistant Superintendent, Business Services
