How To Get Rid Of Greenfly

Greenflies are one of the most common pests to attack gardens. They are attracted to plants by their sweet-smelling honeydew, making it sticky and black sooty mould can grow on top of it. If you notice your plant is being attacked by greenflies, there are many things you can do before resorting to insecticides.

How To Get Rid Of Greenfly?

Greenflies are tiny, sap-sucking insects that commonly feed on the juices of plants. They are about 1mm long and usually found in clusters. Greenflies cannot be seen with the naked eye, so if you see something resembling a small fly it could be these plant pests.

They start to appear during early spring when the weather becomes warmer and reproduce quickly. Once the weather becomes wetter it encourages the greenfly to produce honeydew – a sticky substance that can attract mould spores and grow into black sooty mould, which is difficult to clean off surfaces.

The first way to deal with the problem is by using natural remedies. Insecticidal soap, for example, can be used on new growth which will kill them but won’t harm pets or plants. It is important to make sure it doesn’t come into contact with any part of your body and will need thorough washing off afterwards.

Another option is to plant nectar rich flowers such as fennel and lavender which attracts parasitic wasps that will parasitise the greenfly and kill them before they reach maturity.

Spider mites are another common pest of greenfly and can be dealt with by using natural predators such as Phytoseiulus persimilis (also known as Amblyseius species). These are more effective than using pesticides and, like the parasitic wasp, they can be introduced into your garden at any time throughout the year.

Another trick is to spray neem oil which will not only kill any greenfly that comes into contact with it but also acts as a repellent.

If all else fails, you can resort to using an insecticide, which will also reduce the number of greenfly in the area and help prevent their return. However, be aware that insects will likely become resistant to any spray or remedy over time so it is best to use them as a temporary solution until the problem has been resolved.

Finally, make sure you dispose of any dead leaves and branches as soon as possible to prevent them from becoming home to a new generation of greenfly.

Here are step by step instructions on how to get rid of greenfly

Step 1:

Remove all infected or infested leaves from the plant. Even if it seems like a small problem, if you have greenflies, they will keep coming back.

Step 2:

Spot treat the infested plant with insecticidal soap to kill the greenfly and prevent further infestation during warm months when greenflies are most active.

Step 3:

Step 4:

Pour white vinegar over infected area to kill the greenfly and the eggs.

Step 5:

Re-apply Neem oil to the plant and repeat step 3 & 4. (if you can’t find neem oil, use an insecticidal soap and continue with step 6)

Step 6:

Place a barrier around the base of your plants to stop greenflies from crawling up and multiplying in numbers. This will help to reduce the number of greenflies.

Step 7:

Spray white vinegar all over your plants, this will kill any greenfly that are still alive and prevent them from laying eggs.

Step 8:

If you have a severe infestation, hire a professional to come round and spray an insecticide on your plants. Be careful when spraying insecticide, always wear gloves and avoid breathing in the fumes.

Step 9:

For best results, you should rotate your sprays every week to ensure that any surviving greenfly don’t become immune to an insecticide.
