Public Notice of Mosquito Control Activities

The Skamania County Mosquito Control District will begin seasonal activities around March 26, 2018.   Only when mosquito larva is found will they use one of the following larvicides.

  1. AquaBac G (Bacillus thuringiensis, subspecies Israelensis): specific for mosquito larva
  2. Altosid (S-Methoprene) a growth inhibitor active on early stages of mosquito larva
  3. Agnique (poly-alpha –w-hydroxy): a monomolecular surface film used for later stages of larva and pupa

Later in the season and only in those areas where adult mosquitoes reach thresholds as specified in District IMM plan or if mosquito transmitted disease is detected, will the district adulticide using:

  • Aqua Reslin (permethrin) which is fogged at a rate between 0.0015 and 0.007 ounces per acre.

Mosquito control activities will continue throughout the season until mid to late October depending on weather conditions

Phone or email the Mosquito Control District for further information or to report mosquito problems within District boundaries – (360) 904-4345 or SCmosquitocontrol@gmail.com .  Additional information and schedule changes will be posted and updated on our website https://mosquitoboard.wordpress.com  or http://www.skamaniacounty.org/government/boards-and-commissions .

Happy New Year

December 29, 2017

2017 was an interesting year with the crazy winter and high spring waters into June. It was like all at once the weather turned to a hot summer. Your Mosquito Control District was very aggressive in the early spring and summer controlling mosquito larva, which is the most beneficial time for for control. If we can control in the larva state, it reduces potential for spraying. Thank you to everyone that monitors around their property by limiting mosquito breeding sites, it does make a difference.

Here’s to a wonderful 2018! See you in the spring

As you can see by driving around, we have HIGH WATER everywhere.  Mosquitoes require water to lay their eggs and one female mosquito can lay hundreds of eggs.  Please take a walk around your yard and dump any standing water in any type of container.

The Skamania County Mosquito Control District urges area residents to help control mosquito population. Mosquitoes require standing water for their production. Eliminating standing water early in the spring helps to reduce the production of mosquitoes. Here are a few ideas for searching out and eliminating potential breeding grounds for mosquitoes:

  1. Keep bird baths and ornamental ponds clean. In warm weather, change water weekly.
  2. Remove leaves from gutters so water will flow freely. Fill or drain puddles, ditches and swampy areas.
  3. Eliminate standing water around animal watering troughs.
  4. Check around faucets and air conditioner units and repair leaks and eliminate puddles that remain for several days.
  5. Dispose of, or store in a dry place, any cans, bottles, tires, and any other containers that hold water.
  6. Cover boats or store upside down or in a dry place.
  7. Where feasible, fill all holes in the trees on your property.
  8. When swimming season is over, empty and store wading pools in a dry place. Cover large pools and check frequently to insure against mosquito breeding. Pool chemicals like chlorine, at ordinary concentrations, will not kill mosquito larvae.

Elimination of standing water must be an on going routine to reduce later mosquito problems. Continue to monitor potential breeding grounds throughout the spring, summer, and fall.

The Skamania County Mosquito Control District faces some challenges due to the large number of mosquito producing acres. For many reasons, from staff limitations to restricted access sites, many of the mosquitoes produced in Skamania County are never detected or abated. As a result, mosquitoes looking for resting sites may end up at your home. This is especially true in the rural areas. So the district provides a free service to reduce mosquito numbers for residents in the district who have a mosquito problem around the home. Residents may contact us to schedule a service request. Information about your residence and your problem will be taken and responded to.  We will most likely come out to your home to make an assessment. A recommendation will be made regarding what action(s) should be taken based on the findings.  Often we can find a water source on or near your property producing mosquitoes and can eliminate it, solving the problem.

Please contact us to submit a mosquito control service request.

Mosquito Season 2017 will be challenging.  We have had record rainfall and extremely high river levels, which are in flood stages in a lot of areas.  Access points are currently difficult to access due to the amount of debris down from the winter storms and high water.  All this water is shaping up to give us flood water mosquitoes this year.  The District will be working to access and monitor keys areas that have and do create flood water resulting in mosquito hatches.

We are currently seeing some over winter mosquitoes on the few warm days we have had.  Make no mistake these nuisances mosquitoes will be looking for a location to lay eggs.  Of course with all the water they don’t have to look far.  Please take some time and assess your yards for ANYTHING that HOLDS WATER, planters, gutters, buckets, tires (especially tires), toys, and gutters.  These areas are perfect for a mosquito to lay eggs and make your yard miserable.

Winter 2016/2017 and Mosquitoes

December 23, 2016

We are experiencing a winter like we haven’t seen in several years.  Great snow pack in our mountains, which has been much needed.  However, as we end 2016 and begin 2017 what will the winter mean for mosquitoes in our area.  Honestly, it is a little early to assume.  However, in the past when we have had a good snow pack we typically end up with flood water in the spring.  The real challenge will be the amount of run off and when as well as rain fall.  I will keep you posted on this.

I would appreciate all land and home owners to do their part and keep containers empty around their places, especially as we get closer to spring or when the weather warms up.  If you have any questions or need information about mosquito control in and around your home, please email or call me.  My information is on the contact page.
