How to kill mealybugs

The most effective and less expensive method of killing mealybugs is with the rubbing of alcohol. It is a safe method for your plant too. We will discuss some important things that you must consider while using this method.

Method 01 – Killing Mealybugs with Alcohol:

i). Dip a Cotton Ball in 70% Isopropyl:

First of all, figuring out which alcohol is safe for your plant can be challenging. You can choose 70% isopropyl because it is safe for your plant.

Do not use other types of alcohol because they can cause significant damage. Other types of alcohol could damage your beautiful plants and they can eventually die. Take a small cotton ball and dip it in 70% isopropyl.

ii). Rub the Cotton Ball Over the Infected Area:

It is crucial to rub every infected stem and both sides of leaves with a dipped cotton ball.

Mealybugs make permanent spots on hard-to-reach areas, so rub the cotton ball on every part of the stem, leaves, and other parts of the plant. Rubbing alcohol dipped cotton swabs will easily help to get rid of mealybugs.

iii). Apply Rubbing Alcohol with a Spray Bottle:

For large plants, it is hard and tiring to cover every part with a cotton swab. So, you can use a spray bottle method. Fill a spray bottle with rubbing alcohol and completely spray it on the plant especially on infested parts.

iv). Catching Mealybugs with Hand:

Some mealybugs are large enough that you can easily see. Catching mealybugs with your hand is another effortless method. Pick them and dispose of them. They don’t bite but we recommend using gardening gloves in order to protect your hand from waxy coating.

v). Repeat the Process Weekly:

If your plant is under attack by mealybugs, then you can use the above process weekly until they are gone.

Mealybugs are really good at hiding in difficult spots, so you can use a rubbing alcohol method or spray method on a weekly basis.

Neem oil is such a good oil for killing mealybugs on plants and it is extracted from neem trees. If you don’t have neem oil, then you can use ginger oil for killing mealybugs.
