As young insects, they harm the plants really actively, but this starts to slow down with them growing.

Mealybugs Identification:

Not every white bug needs to be mealybug, so before spraying your plants with the necessary procedure, you can make sure by following a few steps.

  • The size of mealybugs is near about 1-5 to 1/20 inches long, and their original color is pinkish-purple type, but the cotton-like-colored appearance is due to the wax formed on them.
  • They might seem to have so many legs, but the wax creates this illusion on them.
  • The cotton-like protective wax can also give them an illusion of having a tail, etc., by collecting wax at the end of the body and an antenna or tail-like look.
  • There are hundreds or thousands of eggs laid by these female mealybugs and those eggs look like white tiny sacs.

Now that you have verified that the bug you are dealing with is mealybug, the next step is control.

How to kill, prevent, or control mealybugs

Mealybugs are really smart as they have protective wax around them which is made through sucking honeydew etc. from your plants so now all you need to know is how to outsmart them?

Mealybugs are not so attractive towards weak plants, so if you are dealing with only a few of them then you can try not feeding your plant enough for a while and washing the bugs off, it will give you enough time to deal with the issue if not the cure.

You can also make the bugs weak and you can spray your plant with some systemic bug control, and when bugs will suck your plants, they will be weak and then die.

Still, if the mealybugs return back, then you can retry the same procedure that once worked for them which might take time but will be the most effective choice to make.

3 in 1 Mite/Insect/Fung and Mealybug 32 Spray:

After getting to know about mealybugs on your plant, the first step is to decide what kind of treatment you will follow, natural one, organic or chemical one.

Natural procedures are always good, but the result might be time taking and not so promising in the long terms. If your plant is of any edible fruit, you will need to use organic products as it is safer and chemical-free.

The best thing about 3 in 1 is that it controls mealybugs and provides a shield against fungus. Many fungi live inside the mealybugs while many are grown with its help, so it’s good to have a safe organic product and deal with both issues.

To treat an area of 250-500 square ft., you need only 4 OZ per gallon amount of 3 in 1 insecticide and one spray per week is good until the mealybugs are not totally gone.

Then you can spray after every 15 days of inactive months and in months when there is less chance of attack, 1 spray per month will do the job.

Once or twice a week is healthy use but increase it if it rains etc. as there are chances of product being washed.

When using as a systemic, add one OZ in almost 3.5 gallons for trees having 12 inches’ width. Used once in early springs or winters will keep your plants safe for the upcoming whole season.
