St. Louis Mosquitoes – How can I tell them I’m not interested?

Our last article focused on what attracted mosquitoes to us, and this article will lay out some things that you can do to prevent them from getting too close.

We last discussed that mosquitoes are attracted to heat and carbon dioxide.  What this means to you and me is that if you are going to be doing some sort of physical activity outside around dusk, you need to take extra steps to preventing mosquitoes as you will be a greater target for them.  This also means that if you are working around a heat source like a grill or camp fire, you may be again more of a target for them.

The first steps we will talk about will involve things that you can do to prevent the mosquitoes from breeding on or near your property.

  1. Look for standing water.  Mosquitoes require water to be still for about a week to make it from egg to the pupal stage.  They can use almost any source of water such as slow stream, clogged gutters, bird baths, pet dishes, kids pools, soda cans, and even downspouts.  Keep the water moving or dump it and change it out periodically to prevent them from maturing.  If this cannot be done there are several larvicides or “mosquito dunks” that can be applied to these areas to prevent mosquito larva from hatching.
  2. See #1.  That is really the only rule in preventing the mosquitoes from breeding as water is essential to their development.  If the area you find is not on your property you can also contact the county department of health to report a breeding site and they can address it with the property owner.


Next we will look at things that you can do to be a bit more transparent to the mosquitoes.

  1. Repellents.  Love them or hate them they do remain the most effective way to prevent yourself from getting bitten by mosquitoes.  There are many varieties, but the truly most effective ones use DEET as their active ingredient.  Other ingredients may work, but only DEET has been shown to be almost completely effective.
  2. Treat your yard.  This is the one thing that we can help with.  Our mosquito misting service, which targets all of the places that mosquitoes hide out during the day is truly an effective way to limit the number of mosquitoes that try to invade your yard.  We use a backpack fogger to treat all of the foliage around your house and yard witha  microscopic material that clings to the mosquitoes when they land.  This type of treatment is very effective and unlike mosquito mister systems you don’t have pesticides floating around the yard while you are trying to enjoy it.
  3. Avoid peak times for mosquito activity.  Just before sunset to just after is when the mosquitoes are most active.  If you can adjust what you need to do by a little you can avoid most of them.
  4. Wear long sleeves or pants.  I understand that this is not really a great option for a St. Louis summer, but it will make it hard for the mosquitoes to get to you.  So if the weather is nice, or you are going into an area that is really infested it may be worth it.
  5. Don’t forget your pet.  They are just as attractive if not more so to the mosquitoes, so let them in for a bit at dusk, or look for a pet safe repellent for them.

Mosquitoes are much more than a nuisance, they are a specific health threat.  Diseases like West Nile, and malaria kill millions around the globe each year, and there are always a few reported cases each year right here in St. Louis, Missouri.  Take every possible precaution and enjoy your yard and summer, because before we know it we will have a “St. Louis” winter to deal with next.
