Ants on cucumber, what to do?

Ants and aphids form a symbiosis, where there are aphids, an ant nest with lots of hungry ants is not far.

This is a major annoyance for many amateur gardeners. Suddenly they have an ant invasion in the greenhouse or raised bed.

In the following section, I’ve compiled the best immediate measures to help you get your ant infestation under control.
Water abundantly
To get rid of ants on your cucumber plant quickly, water your vegetable plants generously.

Ants do not like wetness and humidity. Damp plants and soil are avoided by them as much as possible.

Relocate ant nests with a flower pot
If you find many ants on your cucumbers, take a flower pot and fill it with newspaper, wood wool and soil.

Trace the ants’ nest and put the flowerpot upside down over the nest.

Wait for some time and exercise patience. The ants will gradually move completely into the flower pot.
Once they have moved into the pot, move the flower pot at least 30 meters away from the place where the nest was first located so that the ants do not return.

Scattering and watering agents against ants

There are a number of biological sprinkles and watering agents available in stores that you can apply to your cucumber plant to repel ants.

Why do ants get on cucumber plants?

Where there are ants, there are usually aphids. If your cucumber plant/zucchini plant is infested with aphids, the ant will benefit.

Ants feed on the so-called “honeydew” of aphids. The honeydew is a sticky mass that the aphids secrete.

To be precise, it is the aphids’ sugary droppings that are at the top of ants’ diet.
Aphids suck the sugary sap from the cucumber/zucchini plant and excrete it again.

Ants are bodyguards
The aphids benefit enormously from the presence of the ants, as they protect the aphids from their predators (e.g. ladybugs) – a perfect symbiosis!

Ants relocate with pot
Fighting aphids
If you fight the aphids, you will also get rid of the ants.

After all, the main reason ants are hanging out on your cucumber plant is aphids.

In my new article: Fighting aphids easily, I explain step-by-step how you can get rid of aphids from your cucumber plant with home remedies and without chemicals.

To get rid of ants from your greenhouse, you can make life difficult for the insects by using broths and dips.

Broth against ants
The following herbs are effective against ants:

  • Thyme
  • Chervil
  • Lavender
  • Marjoram

“To make a broth, soak fresh or dried plant material in rainwater for 24 hours and then boil it for 20-30 minutes. After cooling, strain and the broth can be stored in a jar. For use, depending on the recipe, it is diluted 1:10 to 1:20 times for pest control, disease prevention or foliar fertilization.”

The following yews are effective against ants:
“Jauche” is always made with cold water and can be used fresh, fermenting and biting, or mature and fermented, which is usually the case. The mixture should stand covered permeable to air preferably shone by the sun and must be stirred daily. After 2-3 days, fresh slurry can be used for pest control at a dilution of 1:50. Fermented liquid manure must be stirred 2 times daily and after 10-14 days (longer in cool weather) can be used as a liquid fertilizer and for compost at a dilution of 1:20. Fermented liquid manure is mature when it stops foaming”
