Buying Guide: Key Considerations For Your Fumigation Sprayer
What size tank do you need? Larger tanks reduce refilling, but add weight. For big properties, a 3.7–4 gallon tank is common; for small yards, 2–3 gallon models may suffice. Consider the mix of liquid and powder application if you need dual modes. What about engine type? Gas engines offer high power and mobility but require more maintenance; electric models are lighter and quieter but need battery management or cords. How important is weight and ergonomics? Padded straps and vibration damping help during long spraying sessions. Do you need extended reach? Look for models with long wands and strong nozzles that deliver consistent pressure. Lastly, assess intended usage frequency and local climate; some units excel in warm, humid environments, while others perform better across varied conditions.
