How to Get Rid of White Fruit Flies – What are They?
They can be as tiny as 1/12 of an inch and have an almost triangular shape. Found on the undersides of leaves, they are highly active during the day and quickly scatter when disrupted.
There are many white fruit fly species. Most affect just a few host plants, while a few affect a wider range of plants. These include:
- Giant whitefly
- Greenhouse whitefly
- Silverleaf whitefly
- Banded-winged whitefly
How to Get Rid of White Fruit Flies – Where are They Found?
Since they can’t survive in cold climates, you can spot whiteflies in winter among greenhouse environments or indoor plants. They’re mostly seen in mid-to-late summer when the weather is warm and humid.
They could also become seasonal outdoor garden pests if they’re brought from an infested greenhouse. It’s best to inspect any plants before taking them home!
In warmer regions, they can live through winter and reproduce outdoors all year long, so they can be a major nuisance for both outdoor and indoor plants.
How to Spot a Whitefly
Here’s how you can spot those creepy, pale pests where they’re hiding:
Rugose Spiraling Whitefly
The Rugose spiraling whitefly is almost 0.09 inches and is typically bigger and slower to move than other whiteflies. It has faint brown bands on its wings, and it lays wax-covered eggs in a spiral on the bottom side of leaves.
How to Get Rid of White Fruit Flies – Common Causes of Infestation
Whiteflies thrive in warmer temperatures, like greenhouses or home yards. They can be spotted underneath leaves; they attach their nymphs to the plants and feed off them.
If you bring them home, the infestation can expand in a blink, so beware! Here are some common causes of whitefly infestations for you to take note of:
1. Overuse of Insecticides
This must be a surprise, but insecticides can do more harm than good when it comes to whitefly issues. Many insecticides don’t target specific types of insects, so overusing them can banish the beneficial, predatory bugs.
Spiders, ladybug beetles, and parasitic wasps are natural enemies of whiteflies and can easily finish them off. Unfortunately, insecticides kill these off, so they’re very harmful to any garden’s health.
Water stress makes plants more susceptible to a whitefly infestation. Whiteflies quickly reproduce in hot, dry summers, as well as anywhere with unwatered plants and warm climates.
That said, drought stress can help whiteflies pervade. Pests that pierce or suck need dry weather, which makes whiteflies flourish during a drought.
While a ‘good morning’ from a cute bird is sometimes all you need, some birds are just not your friends. Birds like swallows and swifts can make a meal out of ladybug beetles, which are whiteflies’ natural enemies.
Are White Flies Dangerous?
Thankfully, whiteflies don’t directly harm humans; their direct damage is solely exclusive to plants. While they’re similar to mosquitos, their piercing mouthparts are just used to suck plants’ juices.
When whiteflies suck their fluids, plants can yellow and drop too early or completely die off. Besides, whitefly adults can transmit viruses from unhealthy plants to healthy ones.
They also excrete honeydew—a sweet, sticky liquid that coats leaves. The leaves are then colonized by sooty mold, a fungus that gives leaves a black, dirty look. If abundant, sooty mold can prevent the light from reaching the leaves and cause plant stress.
