But does coffee grounds help against aphids and how is it used? The answers are given below.

Does coffee help against aphids?

Yes. Experience has shown that the residues, which are produced by the ton every day in German households after making coffee, actually work against lice and especially against aphidoidea. This is mainly due to the main component that is contained in the coffee ground. The prerequisite is that the coffee residue is properly prepared and used.

Suitable ground for coffee

Nowadays there are countless types of coffee, ranging from conventional machine coffee to cappuccino and espresso. Scientific tests show that coffee grounds still contain bioactive substances that are released when the coffee is roasted. Espresso from the espresso machine is an exception. With this type of coffee, no noteworthy residues remain in the base of the coffee, because these are transferred into the brewed liquid. This means that espresso is not suitable for combating lice, all other types are, because above all the most important substance still demonstrably present with four to eight milligrams per gram of coffee ground is. Of course, it depends on how “strong” the type of coffee is.

Ingredients and effects

The most important ingredient for the aphid is caffeine. In humans, caffeine stimulates the central nervous system and, by entering the circulatory system, accelerates the heart's activity. If it hits the pests, which are only a few millimeters in size, just a few milligrams of caffeine are enough to develop into a neurotoxin in the body. In other words, it paralyzes all body functions and the lice die of organ failure and suffocation.

The “poison” penetrates the lice through the skin, breathing and body orifices. In the case of coffee grounds, the slightest amount of caffeine enters the louse body through inhalation. Because in this way a promising fight against these pests can take a long time, An appropriate use of the coffee grounds should be made, in which the caffeine goes directly into the body got.

Preparation / preparation

It's not enough to simply spread the compound on the potting soil around the plant after the coffee has been brewed. A brew must also be prepared and sprayed on the plant so that the lice on it can come into direct contact with the caffeine. The production works as follows:

• After preparing the coffee, add hot water again to the coffee grounds
• Catch the liquid
• Tip through a fine-mesh sieve
• Let the sifted brew cool down
• Coffee ground hardly contains any caffeine, so it can be disposed of

tip: It is advisable to alternate between making coffee grounds and coffee grounds. In this way, the maximum possible effectiveness is achieved and the aphids die accordingly faster, if they are sprinkled with caffeine from above and the caffeine from the coffee from below from the ground ascends.
