Mosquitoes, in fact, seem to be inexorably drawn to human skin and blood. It is thought that they can detect our presence through the warmth emitted by our bodies as well as by the smell of carbon dioxide and other bodily secretions. Although mosquitoes have a short lifespan of around 2-3 weeks, they also happen to breed very rapidly.
When the conditions are favorable, the female of the species will lay hundreds of eggs within a very short period of time.

About mosquito sprays for the yard
How mosquito yard sprays work?
Simply put, the liquid insecticide is sprayed over the foliage and grass in your yard and the mosquitoes, flies, gnats, spiders, bed bugs, etc that are exposed to it are slowly killed as are their larvae and eggs. In most cases, these insecticides work by interfering with the insects' nervous system and generally do not kill on contact.
Possible mosquito sprays drawbacks
Some ingredients in mosquito sprays for yard may be quite toxic and environmentally harmful while others may be gentler on both humans and Mother Nature alike.
The active ingredients used in mosquito sprays for the yard
- Sodium lauryl sulfate: Often combined with potassium sorbate and sodium chloride, sodium lauryl sulfate is actually a common ingredient in shampoo and salt. Fully natural and non-toxic, it is a very powerful insecticide not only for mosquitoes but other pests including spiders, gnats and bed bugs as well.
- Lambda-cyhalothrin: This is another ingredient commonly found in mosquito sprays. It is a synthetic pyrethroid, which is a class of chemicals that resembles in terms of structure, the naturally occurring insecticide, pyrethrin, which is found in certain species of chrysanthemums. Despite being a synthetic chemical, it is still low in toxicity and relatively eco-friendly. It is also much longer lasting than many other insecticides. In fact, it will continue to be effective against insects for 4 to 8 weeks after the initial application, even if there is heavy rainfall during that period.
- Gamma-cyhalothrin: This is another insecticide from the pyrethroid class, so it again cannot be considered natural. However, it is still far less toxic and environmentally damaging than many of the other insecticides out there and is very effective as well.
- Permethrin: Another pyrethroid insecticide to which the same conditions as above apply.
- Peppermint oil: Peppermint oil makes a surprisingly effective, all-natural insecticide that will defend you not only against mosquitoes but against many other biting pests as well. Non-staining and with a pleasant, refreshing aroma, this is one ingredient that is ultra-clean to use. If you want to go green with your mosquito spray, then peppermint oil is the choice for you.
- Lemongrass oil/citronella oil/cedar oil: These are some other all-natural, plant-based insecticides that you may encounter in mosquito spray products. Although all-natural and eco-friendly, they still make very effective insecticides.
When it comes to turning your yard into a mosquito-free zone then few products do the job better than a good yard spray. You simply take the bottle, attach it to your hose, and spray the affected areas. There is no greasy residue or unwelcome chemical odor to contend with and many of these products also now contain ingredients that are natural and non-toxic as we have just seen.
