What is whitefly & why is it a threat for plants?

It is a 10th of an inch soft white color insect. You might not be able to see them at first glance because they live in the leaf’s underside. The fly lays eggs there and then feeds on the leaf – resulting in damaging the plant.

The average female whitefly lays 100 eggs. Plus, it takes only three weeks for an egg to transform into an adult. Then the adult whitefly is ready to lay eggs and the cycle continues. This life cycle is the reason why whitefly is difficult because they rapidly grow.

And why you should act fast!

How to Get Rid of Whiteflies?

If you are wondering how to get kill of whiteflies then there are few proven ways for getting rid of whiteflies.

  1. Whitefly Parasite, these are the insects that feed on whiteflies and their eggs
  2. Whitefly sticky trap, small (usually yellow) stickers with thick adhesive
  3. Neem Oil Concentrate Insecticide, an extract of neem tree oil
  4. Horticultural Oil Insecticide, a mixture of different oils
  5. Whitefly insecticide or pesticide spray, a chemical concussion
  6. Whitefly killer soap concentrate Insecticide, the non-toxic soap mixture

How do Sticker Traps Work as a Whitefly Killer?

These sticker traps are not whitefly killers not even a whitefly control system. Just as the name suggests, it is a sticky trap. The user sticks these adhesive traps at different locations in the garden. And whiteflies, as well as other insects, get stuck there. After the trap has caught enough insects, dump it and put on another one.

How to Get Rid of White Flies Using Neem Oil?

Neem Oil has impressive effects on insects. This is why many brands are using concentrated neem oil extract in their insecticide products.

Neem Oil does not only kill the whitefly but gets into the system of the insect. It disrupts the eggs and stops them from hatching. It blocks the growth of larvae and nymphs. The sexual and mating communication of the Whiteflies is also affected, which prevents new egg formation.

Neem Oil also works as a repellent, so new Whiteflies cannot inhabit the place. So how does Neem oil get in the system? Well, there are two ways for that. The concentrated need oil extract is mixed with water and spray on the plants. Then when the insects eat the underside of the leaf, the bean oil gets in the system. Another way is through the skin of the insect. 

How to Kill Whiteflies Using Horticultural Oil?

Whitefly treatment using horticultural oil is effective. Unlike Neem oil, horticultural oil does not get into the system of the insect.

Usually, soft insects like Whiteflies, mite, etc, breathe through their skin. When horticultural oil is sprayed on the Whitefly colony, it covers the insect body. Following this breathing becomes impossible for the insect. That result in the death of the colony.

Using Horticultural Oil is one of the ideal ways to kill Whiteflies. The oil is not sprayed directly, but first, you have to mix it with the water. The ratio is instructed on the bottle or instructions.

How to Get Rid of Whiteflies on Plant Using Soap Concentrate?

These white bugs on the plant can destroy the fruits if not treated earlier. For many years, gardeners have used soap mixture to kill Whiteflies and other insects. However, after the industry started adding toxic chemicals in the soap Insecticides, the option was rejected.

Well, now organic farming is in the peak. Which is the reason why many companies have started producing non-toxic soap concentrate. Add some water and you are good to go.

It works similarly to the horticultural oil. The soap mixture penetrates the skin of the insect. This suffocates the insect and stops the population growth.

How Do Chemical Insecticides Work as a Whitefly Treatment?

The market is filled with toxic chemical sprays and it is easy to find a Whitefly chemical control. But due to the high toxicity level, these sorts of products are not recommended.

Yes, the chemical insecticide will get rid of the whitefly and work as a great killer. But it can easily damage the plant itself. Other than that, the product is also not safe to use around pets and children.

When & How to Use Insecticides/Pesticide?

No matter if the product is organic or not, or if it is the best insecticide for Whiteflies. Cover your body and face first. Even inhaling non-toxic Pesticides is not ideal.

Most of the time, the product has mentioned on the label the instructions. But usually, the concentrated insecticides are diluted and then sprayed every few weeks. You can spray them every 3 to 4 weeks, till the insects have reduced in number. After that spraying, every few months for a systematic elimination is the best way to keep them in check.
