Residual sprays keep mosquitoes away from the lawn.
To get rid of mosquitoes outdoor, you will achieve the best and most long-lasting results if you use residual sprays. Spraying your grass with residual sprays kills adult mosquitoes and helps reduce the risk of mosquito bites. You need to use certain equipment and certain types of insecticides to effectively control mosquitoes using residual sprays. Does this Spark an idea?
Effects
Residual mosquito sprays provide long-term protection that lasts between several days and several weeks. When you apply the insecticide, it kills any mosquitoes flying in the area or resting on the grass. As long as the insecticide on the grass remains effective, the mosquitoes that land on the grass will be exposed to enough toxins to kill them. The length of time the insecticide remains effective depends on various environmental factors, such as rain and temperatures.
Application
Residual sprays work to prevent mosquitoes from entering a certain area, such as your lawn, a park or a sports stadium. You may apply the insecticide on the grass using a mist blower, pump sprayer, power backpack, hand sprayer or compression sprayer. Although the insecticide may provide protection for weeks, you should time the treatment to be about one or two days before any outdoor event to minimize the risk of the insecticide losing its efficacy too quickly.
Insecticides
There are several different active ingredients a residual spray insecticide product may contain. Some active ingredients include carbaryl, cyfluthrin, deltamethrin, malathion, permethrin or pyrethrins. Each product has a different formulation, active ingredient concentration and application rate. You must always follow the product label instructions closely when working with insecticides. To prevent the residual spray treatment from damaging your grass, choose an insecticide product that is water based instead of oil based.
Warning
Some active ingredients of residual sprays may harm wildlife. For example, malathion and methoxychlor may kill fish if they seep into water. Malathion and carbaryl may poison and kill honey bees, which are beneficial pollinators in the garden. To minimize damage to honey bees, avoid spraying the grass when there are flowers blooming in the area. Apply residual sprays during times in which honey bees are not active, for example in late afternoon or when temperatures are 45 degrees Fahrenheit or lower.
