Demon WP is labeled for mosquitoes though it will leave a white residual that is visible on darker surfaces. According to the Demon WP product label: For mosquito control, apply as a general structural perimeter spray to landscape plantings, turf, and building foundations to control mosquitoes. Yards or other frequented areas enclosed by landscaping can benefit from the creation of a mosquito barrier to reduce invading mosquitoes by the treatment of perimeter vegetation. For best results, apply Demon WP at recommended rates in 2-5 gallons of water per 1,000 sq. ft. Higher volumes applied result in better coverage and, as a rule, will improve control.
For mosquitoes, key is to apply to the underside of leaves on trees/bushes which is where the adults lay during the day, as well as in shady areas. You would not treat entire areas of the lawn that are in full sun as it is not habitable for them there.
