Apply systemic insecticide with imidacloprid for long-term control
Step 5
Install yellow sticky traps to monitor population reduction
Step 6
Repeat foliar treatment after 7-10 days if needed
Organic Treatment
Step 1
Spray plants with strong water jet to dislodge whiteflies, focusing on leaf undersides
Step 2
Apply neem oil solution (1-2 tbsp per quart water with mild soap) every 5-7 days
Step 3
Use insecticidal soap spray covering all leaf surfaces, repeat every 3-4 days
Step 4
Release beneficial insects: Encarsia formosa wasps, ladybugs, or lacewing larvae

- â Install insect-proof screens on greenhouse vents and doors
- â Maintain good air circulation between plants
- â Monitor plants weekly for early detection

ðą How to Care for Water Mint to Prevent Whiteflies?
ð§ How to Water
Keep the soil saturated at all times, or grow water mint directly in shallow water up to about 5-8 cm deep. It tolerates being submerged far better than it tolerates drying out, so err on the side of too much water rather than too little.
âïļ Lighting
Full sun produces the most compact, flower-rich growth, but water mint also tolerates partial shade, especially in hot climates where some afternoon cover prevents leaf scorch.
ðŠī Ideal Soil
Grow in rich, loamy or boggy soil with a slightly acidic to neutral pH of about 6.0 to 7.0. Heavy, water-retentive soil is ideal since this plant naturally grows with wet roots.
