SUMMIT Mosquito & GNAT Barrier Concentrate – 1/2 Gallon, Natural Insect Spray

Overview

Summit Mosquito & GNAT Barrier Concentrate is a versatile outdoor spray designed to help manage common yard pests. Easy to mix with your existing sprayer, it targets resting mosquitoes on vertical surfaces like fences, decks, and shrubbery, aiming to reduce bites and buzzing for weeks.

What makes this formula effective

The concentrate contains permethrin, a residual insecticide with decades of mosquito control use. When applied to vertical surfaces where mosquitoes commonly rest, the product can help reduce activity and the number of pests you encounter outdoors. Results vary with conditions, but many homeowners notice a calmer outdoor environment for several weeks.

Key advantages

• Keeps mosquitoes away for up to four weeks
• Also targets fleas, gnats, ticks and other outdoor insects
• Spray paths and wooded areas to reach ticks
• 64 oz value size concentrate, enough to make up to 50 gallons of finished spray covering up to 10,000 sq ft
• Easy to mix with your own sprayer and harmless to garden plants

Smart coverage and usage

• Apply to vertical surfaces where pests rest, like fences, decking, and shrubbery
• Spray lawns to control chinch bugs, crickets, grasshoppers, grubs, mole crickets, and sod worms
• Treat trees and shrubs for caterpillars, aphids, bagworms, leafminers, mealybugs, spider mites, whiteflies, and more

Usage and practicality

Mixing is straightforward: pour the concentrate into your sprayer and add water per label directions. The 64 oz bottle is designed to yield up to 50 gallons of ready spray, giving you ample coverage for larger yards without constant refills. The spray can be applied to lawns, trees, and shrubs, though you may want to focus on boundary lines and high-traffic outdoor areas.

For best results, plan applications during calm, dry weather and avoid spraying when rain is imminent. Spot-treat heavily infested zones and reapply as recommended by the label to maintain control over the season. Always test a small area first to ensure no plant damage.

Real-life benefits

Outdoors time becomes more comfortable when pest activity is less noticeable. The concentrate is designed to cover large areas efficiently, making it a practical option for seasonal pest management around patios, fences, and landscaping beds. While results will vary, many users associate fewer interruptions from mosquitoes, gnats, and other common pests after treatment.
