Please take a few minutes and walk around your yard and house to check for any standing water.  This includes rain water that has filled any planters, buckets, tires, gutters, bird baths, etc.  Mosquitoes will lay their eggs in these areas and these areas typically have quicker hatches as the water warms more quickly.  If you can dump these items, it helps immensely.  The more we limit the standing water breading areas, the less backyard mosquitoes there is.

Thank you, your help is appreciated!


Protection around your home and self

May 11, 2016

Doing and keeping up with the following will help control mosquitoes around your home and yard, which helps protect you.

Protect yourself
Regularly drain standing water from containers such as flowerpots, pet bowls, birdbaths, bucket,  barrels and cans.
— Keep rain gutters clear.
Remove discarded tires and other objects that could catch and hold water.
— Check for puddles around faucets and air conditioners.
— During swimming season, keep pool water circulating and filters running.
— Empty and store wading pools in a dry place after swimming season.
— To avoid bites, keep window screens repaired, place netting over infant carriers and wear long sleeves and long pants

Adulticiding Information

May 11, 2016

As a reminder the adulticiding (fogging) schedule will be posted under the “Adulticiding Schedule” heading on this website.

Please take some time and walk around your yards and or property to check for any standing water.  This can be water in cans, tires, planters , etc.  mosquitoes THRIVE in these areas and MUST have water to lay their eggs in.  We appreciate you doing your part in controlling the mosquitoes/larva in your area.

How to Make A Mosquito Free Yard

April 4, 2016
  1. Tip containers to drain water
    Mosquitoes don’t need much water to breed, so reducing — if not eliminating — standing water is the first step in eradicating the mosquito threat. “We create all sorts of areas for water to collect, which provides a breeding ground for mosquitoes, noting that a 6-inch-diameter plant saucer with only a half-inch of water can be enough for mosquitoes to reproduce. All they need is eight to 10 days for eggs to turn into adult mosquitoes. It doesn’t take long, just look at the mosquito life cycle information on this site.

The District advises tipping any item that contains stagnant water, such as plant saucers, dog bowls and
birdbaths, on a regular basis. Then, if needed, fill them with fresh water.

  1. Toss unnecessary items
    Really, we’re our own worst enemy. We create mosquito habitats close to our house. So if your yard is full of items that you don’t need and that are holding water, get rid of them. Old tires, for example, are notorious for retaining water that allows mosquitoes to breed. Throw them out or, if you’re using one for a swing, drill a hole in the bottom so the water can leak out. Also, clean your gutters so the water can drain freely.

Trees and plants near the house provide shade and housing for mosquitoes, while stagnant water and organic material, such as leaves, give mosquitoes everything they need to breed and survive. The better manicured lawn, with brush trimmed back, eliminates the areas that can be used as habitats.

  1. Turn over buckets and pools
    Kids’ toys, buckets, wading pools and anything else that holds water but you don’t want to throw out should be flipped over when not in use.

For water that can’t be drained, such as what accumulates in fish ponds or ditches, call us and we can take a look at the area for possible treatment with BTI.

  1. Tie your tarps tightly
    If you’re using a tarp to cover a pile of firewood, a speedboat, your grill or any other large items, make sure it’s pulled tight. Otherwise, rainwater pools in the folds and the low spots. If the tarp can’t be pulled tight, remove it so the water drains.

Public Notice of Mosquito Control Activities – 2016

The Skamania County Mosquito Control District will begin seasonal activities around March 29, 2016.   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 . Additional information and schedule changes will be posted and updated on our website or .



2015 Wrap-Up

January 6, 2016

2015 was a very mild year for your Skamania County Mosquito Control District.  Due to low snow packs we did not experience the flood water that we typically do.  The lack of flood water in the primary breeding areas resulted in much less larva in all areas we have access to.  We will assume the same situation in the areas we do not have access to.

Also, the more individuals can do to control mosquito larva and therefore mosquitoes around their homes, the more pleasant evening are felt from everyone in the area.

  • Remember, standing water means mosquitoes. Any standing, stagnant water that remains for 7 to 10 days after a rain can, and usually will, produce mosquitoes. For example, one coffee can full of water has been shown to produce in excess of 10,000 mosquitoes over an entire summer season.
  • Empty all water holding containers in your yard on a regular basis, at least once a week, children’s wading pools, rain barrels, buckets, bird baths and stored boats are prime examples of mosquito breeding sites.
  • Over-watering and poor irrigation practices are common producers of mosquitoes around the home, in parks and on golf courses. Report standing water to appropriate maintenance personnel.
  • Clean out eaves troughs and down spouts of leaves and other debris that slows drainage.
  • Ditches must be kept free of vegetation and other debris to promote rapid drainage, and pond edges should be kept clean of cattails and other aquatic vegetation. This is where mosquito larvae develop and mature. To reduce the number of adult mosquitoes in your yard:
  • Keep your lawn mowed as short as is practical.
  • Keep all ornamental shrubs and bushes trimmed and pruned to open them up to light and air flow. This will not only give mosquitoes one less place to hide, but will promote growth and vigor in the plant.
  • Cut back as far as possible, all low, dense under-growth surrounding your yard. This is where mosquitoes go to hide during the day.
  • Have large trees trimmed to allow sunlight to penetrate dark, damp areas.
  • Plan outdoor activities and parties during daylight hours or later in the evening. Many mosquitoes are most active at dusk and for about an hour after dusk.
