Whitefly Pest Problems
They Breed Quickly!
- Use sticky traps as an early warning and to slow their progress ($3 each or 4 for $10)
- If left alone they will lay lots of eggs today and they will hatch over the next few days
- They suck the sap out of the plant reducing the plants energy and also leave a sticky urine behind that causes damage to the plant
Spray with an Aerosol into the air.
- In the past we would spray a toxic chemical onto a plant so the insects would land on the leaves and die.
- Never use a household fly spray on plants - they can get very sick. Use plant based sprays.
- What we try to do now is spray something safe for plants
- but still avoid excess on the plant itself. You should be spraying the insects mainly.
- Spraying pesticides onto the plant can result in damage so don't be very concerned but avoid spraying it all over the plant
- Products like Kill-a-Mite, Ed Rosenthals Zero Tolerance and other products are reported by customers to be successfull
Shake the plant so the White fly are up and active
- They beat the air with their wings, and the tiny droplets of the aerosol that float in the air will be attracted to the static electricity of the insect flying.
- You won't have to use too much to get a big knockdown.
- The plants will only have a minimal amount of overspray
- and that's ok. Spray often
- once or twice a day
- Spraying once will kill only today's adults.
- As the eggs hatch you need to kill them before they lay more eggs.
- Within a couple of days you should see a good reduction.
- Keep an eye out for slow hatching eggs.
Whitefly leave a residue.
- This is their urine. it's sticky and can cause issues like mould or clog up leaves.
- Some growers will use a drop of dishwashing detergent and some water and spray it onto the plants to unclog the plant.
- If you do spray a plant with detergent like this, do so before end of the daylight/ light cycle. This will allow the fluid to evaporate overnight.
- Dishwashing detergent is ok for plants in small amounts
- avoid too much or you will get lots of foam. It's mostly phosphorus and non-toxic to humans as well. Perfumes in the detergent may have an oil base but you'd need to use half a bottle for it to be an issue.
Now go and eradicate those pesky bugs!
