F.A.Q.

Are DIY mosquito sprays effective?

DIY mosquito sprays provide short-term, localized relief. But they don’t deal with the population at its source in the same way that sustained, property-wide control does.

If you’re like a lot of consumers, you’ve probably seen mosquito repellent spray at the hardware store for a few dollars. The label promises to kill mosquitoes on contact, and it seems simple to use. So you may wonder why professional treatment is necessary, and that’s a reasonable thing to wonder about.

The problem with mosquito sprays is that consumer-grade ones use lower concentrations of active ingredients than professional products. They’re also applied with spray cans or low-powered spray nozzles that cannot match the coverage, droplet size, or penetration of a backpack mist blower or truck-mounted sprayer. The treatment will reduce mosquitoes to some degree, but if they are five feet deep into a border of shrubs, it probably won’t help.

Most DIY sprays work on contact, which means they control what they touch. They don’t leave a meaningful residual barrier treatment on the vegetation. Professional treatments work differently, and are formulated to bind to leaf surfaces and keep working for weeks. That means mosquitoes that landed on treated foliage will still be controlled long after the application dries.

There is one more big difference between DIY and professional mosquito control, and that is how the treatment is applied. Skilled technicians will often target places where mosquitoes are known to spend time, like shaded vegetation or standing water. Homeowners, unless they happen to know about mosquito habits, will often spray the places where they are annoyed by mosquitoes, like the deck or seating areas. The professional treats the source of the problem that the homeowner would likely miss.
