Top 5 Best Mosquito Yard Sprays (2021 Review)

Ortho Home Defense is a high-end insecticide concentrate meaning that you mix a little bit with a gallon of water, and depending on how often you use, it may be the last bottle of insecticide you use.

Generally, you mix .2 to .4 of an ounce to a gallon, which, as you can imagine, makes an 8-ounce bottle last a long time, so just imagine how long a 32-ounce bottle will last you. Make sure to read the label for exact mixing instructions; if you get the dose incorrect, you won’t see the results you want.

Ortho Home Defense has a use for most kinds of pests you will find outside of the home, of course, that includes mosquitoes. You will need a handheld sprayer, Ortho’s hose attachment, or a power sprayer of some sort to apply it correctly.

This product can not be used indoors. However, it can treat the perimeter of your home to help keep the insects out in the first place. In total, you will have enough product to treat 5300 square feet.

Pesticides come in all shapes, sizes, and consistencies these days. They may have different labels and different brand names but what is really important is the active ingredient and the concentration in the product.

Demand CS may not be a name brand name that everyone recognizes, but at its heart, it uses a well-known pesticide to kill mosquitoes known as Lambda-cyhalothrin1. Lambda-cyhalothrin1 has been used for yard flea and mosquito treatments for a very long time and has a high success rate.

When it comes to yard treatments there are two main ways to apply a product. You either use granules that act as a slow-release capsule or you use a liquid formulation that starts working as soon as it is applied.

With granules, you need to wait around three days for them to get wet enough to release the pesticide and start doing its work, and then it can take another 3 to 10 days for the insects to start dying off. With the liquid concentration, you skip the need for the initial three days and get straight to work, removing these biting pests from your yard or building.

There are powders as well but they generally don’t stand up well to the rain and not only do they stain but it can be annoying to apply a powder to a large area.

While the product says that it doesn’t have a smell, some people say that it does. This may not be a huge deal as you are most likely using this outside. This product also has another slight drawback and that is it requires a sprayer.

Demand CS is also safe to use on ornamental plants such as decorative bushes around the property or home. That being said, always read the label before use and make sure not to use it on any plant or area that you plan to use for food.

EcoGuard is a blend of Cedarwood oil, 2-Phenylethyl propionate, and Geraniol. They act to repel mosquitoes and other insects. There are instructions on the back for using it in a hand-held pump sprayer or a mist blower. Follow the instructions carefully because they are different depending on how you plan to apply it.

It is all-natural so there aren’t any chemicals to worry about for your children or pets. It has to be reapplied on a regular basis though, about once a week or after it rains. If it rains, wait until the rain has dried then immediately reapply it.
