Cochineal: treatment, control and solution for your plants


The mealybug is one of the most common pests on our houseplants.

But it can also be found in the garden in late spring, summer or fall.

Its damage is variable, as much as the form it can take to conceal itself.

Oval in shape, the mealy mealybug is often covered with a white or pink mass which gives it a cottony appearance.

There are also shell mealybugs brown in color that look like small black cases hanging from stems and / or leaves.

Mealybug season

There is not really a good time or season but rather conditions for development. Mealybugs love the heat and some humidity ambient.

  • We find them throughout the year on indoor plants.
  • They are common in spring, summer and until early autumn in our gardens and can affect all types ofshrub.
  • They cannot develop outdoors in winter, but cleaning infested areas is still recommended.

Conditions conducive to mealybugs

As we just said mealybugs love heat and humidity.

  • They particularly like confined, humid environments and high temperatures.
  • Interior wet or the fact of regularly spraying water on the foliage accentuates the phenomenon.
  • Likewise, at the end of the spring or at the start of autumn when temperatures are high enough and the outside air is more humid.

Having mealybugs on a plant is often a contagion factor for other plants.

Danger to the plant

Mealybugs should be taken seriously because an attack can permanently condemn your plant.

  • It feeds on the sap of the plant, which eventually weakens.
  • This impairs the proper development and growth of plants and can cause the appearance of a black fungus called sooty mold.
  • On fruit trees such as citrus, mealybugs can compromise the harvest or even doom the tree if they are not treated in time.

Anti-cochineal treatment

There are several ways to fight against mealybugs, of which certain treatments, 100% natural and organic, have been proven.

  • As soon as the cochineal appears, remove their shells with a cloth soaked in beer, 90 ° alcohol or soapy water, then treat with an anti-cochineal product.

Natural and organic anti-cochineal recipe:

The best recipe is to dilute in 1 liter of water, 1 tsp of liquid black soap, 1 tsp of vegetable oil and 1 tsp of 90 ° alcohol.

You spray this solution 1 time per day for 3-4 days.

  • There are also anti-mealybugs based on white oil that have been proven to work. You will find them in specialized stores.

> You can also limit their progress with a powerful jet of water or by cleaning the leaves with a cloth dampened with 90 ° alcohol and then rinsing with clean water.

> A spray based on nettle manure is also effective in the event of an attack.

> Attention, you must deal quickly at the risk of seeing the plant totally invaded and condemned.
