Mosquitoes lay their eggs in or near bodies of still, stagnant water. These eggs will then hatch in the water, and the resulting larvae will live there until they become adult mosquitoes. Finding a pool of standing water on your property infested with mosquito eggs or larvae might be unpleasant, but it gives you an opportunity to intervene and deal with the mosquitoes before they reach maturity. Once they’re airborne, they are much more difficult to deal with.
If it’s feasible to remove the standing water and dump it somewhere harmless, this is the quickest and easiest way to eliminate the mosquitoes and remove a potential breeding site. But for larger bodies of water, scooping it up one bucket at a time is far too labour intensive and time-consuming.
Fortunately, if you can’t remove the water itself, there are several simple DIY home remedies that will effectively smother most of the larvae. You can add washing up liquid or cooking oil to the water, creating a layer on the surface. This surface layer prevents the mosquito larvae from breathing the air above. However, be careful; this layer will also prevent the exchange of oxygen between the water and the atmosphere. If any fish are living in the water, they will suffocate and die along with the larvae.
You can also make your own larvicidal spray by mixing apple cider vinegar with water. Combine them in a ratio of at least 1:4, but don’t be afraid of adding more apple cider vinegar; the stronger, the better. Spraying the larvae directly with this spray should take care of them within 24 hours. This spray also makes an effective mosquito repellent if any of the larvae do reach maturity.
To prevent problems with mosquitoes in the future, remove standing bodies of water on your property and fill in any holes or ditches that fill with water after heavy rain.
