A Top Solution To Get Rid Of Scale Insects

With their nasty habit of sucking the sap of plants with their rostrum, these small parasitic insects are a bit like vampires!

However, once these pests are there, it is better to act quickly, because they are not easy to dislodge.

Observation is therefore a key element to unmask them as soon as they arrive and could be followed by quarantine to avoid spreading! It is also necessary to prune the trees, remove dead branches as well as the infested pieces that you must burn. But above all, when the invasion of harmful mealybugs is declared, do not hesitate to concoct this very effective super mixture. When sprayed, it will help the gardener in his biological fight against mealy bug infestations.

What you need:

-One teaspoon of liquid black soap
-Then another teaspoon of alcohol at 90
-And finally a teaspoon of soybean oil (or other vegetable oil like rapeseed oil)
-Spray bottle

1) You need to dilute your black soap, alcohol and soybean oil in a liter of water and mix well. You can do this directly in your spray bottle. Your insecticide is already ready to use.

2) Put a plastic film on the surface of the jar to avoid getting product in the soil.

3) Spray your treatment solution on the leaves, both above and below. These bugs tend to hide under the leaves, so don’t leave out any nooks and crannies! Then, repeat the spraying an hour later on the host plants.

4) Do this once a week for two months. The infestation and proliferation of this parasitic insect pest will no longer be a problem on your indoor or outdoor plants (orchids, cacti, trees and shrubs, certain ornamental species, etc.).

This mixture is highly effective, but if you don’t feel like buying these natural ingredients, there are other methods.

-Up to three times a week, treat attacked plants with a product made of one and a half liters of water and 150 ml of black soap (natural insecticide). This soapy water spray can also be effective against aphids and other predators for your green plants. You can also make a spray of nettle manure.
-Also, you can make a more concentrated mixture of water and black soap to sponge on the plant.
-Soak a cotton swab with methylated spirits or white vinegar and dab the scale. Household alcohol or rubbing alcohol will remove the shells. However, do not pour it on the roots or the soil!

In addition, a few maintenance measures can help against mealybugs. First of all, as explained earlier, you will need to do some pruning, as unpruned trees attract them. Also, scrape the soil under the trees and plants, because mealybugs and their larvae find refuge there during the cold seasons while waiting for the summer. Finally, several species of ladybugs and hymenopterans are its natural enemies and allow to fight against the mealy bug and eradicate it. As you can see, there is no need for insecticides or traps based on chemical products from garden centers to save infested plants.
