Gardening- how do you kill off whiteflies?

Answer 1

If all of the options submitted by other did not work, try this: fill a sprayer botle with a teaspoonfull of dishwashing detergent (the one you use for manual dishwashing, like Palmolive or anything you use) and top it off with water. Spray the plant with this mixture. Remember to spray under the leaves, that's where they deposit their eggs. Do this every 4-5 days until they are all gone. It works everytime for me!
GOOD LUCK!!

Answer 2

Get a clear plastic bag, put some basil in it & tie it tightly over the houseplant. Leave this way for 3 weeks. It isolates your infected plant, suffocates the flies and the basil has pesticides in it.
No need to water more than once--the bag also acts as a terrarium. Make sure it is not in bright light, as it will heat up quickly in sun.

If your infestation is really advanced, try repotting the plant before doing the above--throw old soil away and rinse pot with warm soapy water and vinegar.

When whitefly is gone, water less frequently and use a systemic, or slow release fertilizer that can be applied dry and scratched into the soil. That way, when you water, plants will be fed.

Good luck!

*
Learn to recognize beneficial insects. Among the most important natural enemies of whiteflies are the tiny parasitic wasps that lay their eggs inside the bodies of whiteflies. These tiny wasps cannot sting people.
*
Attract beneficials to your garden by planting a wide variety of flowering plants or certain insectory plants (See article or fact sheet in this series called “Naturally Managing Pests… With a Healthy Garden”) can provide beneficial insects with the habitant they need (food and shelter). Natural enemies that attack many whiteflies are small birds, spiders, lacewings, ladybugs, and big eyed bugs.
*
Inspect new plants carefully. Don’t purchase infected plants.
*
Hang sticky traps above the plants at the beginning of the season to detect an invasion early.
*
Use slow-release fertilizers. Maintain healthy plant growth, but do not over-fertilize with high nitrogen fertilizers. Too much nitrogen can overstimulate succulent plant growth, prompting some aphids to reproduce more quickly. Organic fertilizers are better because they slowly release moderate levels of nutrients.
*
Avoid excessive pruning because it stimulates whitefly-attracting growth.
*
Use a row cover (such as FastStart®) to exclude whitefly and other pests but allow air, light, and irrigation water to reach plants.
*
Control ants by spraying or painting a 4” wide sticky barrier (such as Tanglefoot ®, Stickem ®, Tree Pest Barrier) around woody shrubs or trees. (See the Ant article or fact sheet in this series.) For many sensitive trees, such as citrus, a protective barrier of white latex paint should be appliedto the trunk before sticky barrier.


Good luck hope it helps

Answer 4

Somebody told me that whiteflies were attracted to yellow, so to hang a piece of plastic up in the garden, smeared with petroleum jelly (vaseline) and the whiteflies would stick on it! Hope this works, I'm going to try it this year.

Answer 5

White flies are attracted to the yellow sticky-fly tape. Stake a few around your affected areas.If they are on particular plants, stake them near about the same height as the plants. It is a little late to introduce beneficial insects and their eggs. This is generally done in the spring. How ever inviting birds to your garden area will also help a great deal. A near by bird feeder will call them in.A hard spray with the garden hose as you water will also keep many pests away.A weekly mist of soapy water(a few drops of dish soap in a spray bottle of water) will help to keep aphids, whites flies and spider mites from making a home on your plants.
