The SUMMIT concentrate is formulated to kill and repel mosquitoes for up to four weeks and also targets fleas, gnats, ticks, and other insects. It works by spraying along paths and wooded areas to disrupt tick activity.

Buying Guide: Key Considerations For Choosing A Mosquito Spray For Plants

  • Coverage area: Outdoor-focused sprays typically require larger volumes or concentrates. For patios and yards, consider hose-end or concentrate formulations that scale to your space.
  • Active ingredients: Plant-safe formulas often use essential oils, neem oil, or botanical extracts. Choose based on whether you prioritize pet safety, indoor use, or quick knockdown.
  • Application method: Sprays with ready-to-use triggers are convenient for indoor plants; hose-end or concentrate products suit larger outdoor areas.
  • Plant compatibility: Some products may affect delicate ornamentals or finishes. Always apply according to label directions and test on a small area first.
  • Residual effect: Some products claim several weeks of protection; others require more frequent reapplication after weather events.
  • Safety for pets and kids: If you have curious pets or children, prioritize formulated products that emphasize safe use with normal reentry times as directed.
  • Indoor vs. outdoor use: Indoor plant sprays should avoid lingering odors and residues, while outdoor products may emphasize weather resistance and broader pest control.
  • Cost efficiency: Consider size and number of applications per bottle or concentrate to estimate long-term value for your space.
