Buying Guide
What should I consider before buying a malathion spray?
- If your primary goal is mosquitoes, confirm the label lists mosquitoes among the affected insects and consider concurrent pests like aphids or spider mites.
- All products here are intended for outdoor use. Do not apply indoors unless the label explicitly allows it.
- Review which plants are listed on the label to avoid applying to edible crops or blooming ornamentals during pollinator activity.
- Concentrates require mixing; ready-to-use or ready-to-mix options save time but may demand more frequent applications under heavy pest pressure.
- Higher percentages offer stronger knockdown but may increase phytotoxic risk if misapplied. Follow dilution instructions precisely.
- Check reentry intervals for outdoor spaces where people and pets frequent, and maintain appropriate distances from water sources and beneficial insects.
Application Tips
- Apply during calm, dry conditions to minimize drift and maximize residue contact on target insects.
- Avoid spraying flowering plants to protect pollinators unless the label permits.
- Use proper protective equipment as indicated on the product label when mixing and applying.
