Aphids are semi-microscopic pests – seen with regular eyes or better with a microscope – that come as predictably as the change of season. Each spring as the weather warms up and rains fall in greater volumes, the aphid population rises faster than your pumpkin seedlings. In a blink of an eye, many hundreds of aphids take up cover and a feeding spot on your plants eating them from the inside out.

When eating, they create a sugary substance called honeydew, that then feeds their no.1 ally, the ant. If you happen to notice ants scampering up and down your plants, you can be sure that aphids are somewhere to be found.

Optimal Conditions

Wet and warm (also known as spring)


Clusters of small black or green dots on the stems of your plants and underside of the leaves. Turns the leaves yellow by sucking out their sap and then leaves behind a sugary residue - called honeydew - that ants feed on. An abundance of ants, that then protect the aphids, is a tell tale sign of a problem.


Keep the plants well spaced for good airflow and consistently watered to reduce plant stress. Don’t overfeed with nitrogen, which tends to make plants more susceptible.


Accept that it’s seasonal and apply a soapy spray to clean the leaves of aphids, the honeydew and the ants. Don’t use chemical fixers, which will discourage predators to come in and help.


White oil (or eco oil), applied on a dry day in the morning and then reapplied in similar conditions a few days apart to compound its effectiveness. You should also introduce the aphids’ number one predator, the ladybird. Go get ’em guys!
