Whether a one-time spray treatment to control mosquitoes is enough depends on multiple factors. Often, you’ll notice a big difference after one application. However, mosquitoes are likely to return if you don't reduce attractive standing water habitats. This usually takes four to eight weeks if it’s still prime mosquito season.

Very carefully. You should be cautious when using any of the above methods, as any one of them could lead to you accidentally killing desired grasses and plants. However, there are selective herbicides that can target certain plants over others. Look for a product that only affects the type of weeds you want to eliminate and spares the plants you want to keep.

Each season’s climate influences approaches needed for effective suppression.

All herbicides come with risks, but you can control and mitigate risks by discussing your options with your weed service company before application. Some companies use milder or sustainable herbicides more times per season to control weeds rather than one to two herbicide sprayings annually. You can also ask your professional about pet-friendly and kid-friendly services. In most cases, though, you can wait a few days after the application for the herbicides to soak into the ground, at that point they shouldn’t pose a risk to you or your family.
