Updated: April 2, 2022

Dusty Miller is a beautiful plant with silvery leaves that add an elegant touch to any garden. However, it can attract pests such as slaters, which can damage the plant and make it look unsightly. Slaters are small, grey insects that like to hide in damp areas, and they can be difficult to get rid of. In this article, we will discuss some effective ways to eliminate slaters from your Dusty Miller plant.

Identify the Problem

The first step in getting rid of slaters is identifying the problem. Look for signs of damage on your Dusty Miller plant, such as holes in the leaves or chewed stems. You may also notice slaters hiding under the leaves or in the soil around the plant. Once you have identified the problem, you can take steps to eliminate the pests.

Natural Remedies

If you prefer natural remedies and don’t want to use chemicals on your plants, there are several options to try:

Diatomaceous Earth

Diatomaceous earth is a natural insecticide that is effective against slaters. It works by dehydrating the insects and causing them to die. To use diatomaceous earth, sprinkle it around the base of your Dusty Miller plant and on the leaves. Be sure to wear gloves and a mask to avoid inhaling the dust.

Coffee Grounds

Coffee grounds are another natural remedy that can repel slaters. Sprinkle used coffee grounds around the base of your Dusty Miller plant or mix them with water to create a spray that you can apply directly to the leaves.


Vinegar is a natural insecticide that can repel slaters. Mix equal parts white vinegar and water in a spray bottle and apply it directly to the leaves of your Dusty Miller plant.

Chemical Treatments

If natural remedies are not effective, you may need to use chemical treatments to eliminate the slaters. Always follow the instructions on the label and wear protective clothing when using chemicals.

Insecticidal Soap

Insecticidal soap is a safe and effective way to control slaters on Dusty Miller plants. It works by suffocating the insects and disrupting their cell membranes. To use insecticidal soap, mix it with water according to the instructions on the label and spray it directly onto the leaves of your plant.


Pyrethrin is a chemical insecticide that can be used to control slaters. It works by attacking the nervous system of the insects and causing them to die. To use pyrethrin, mix it with water according to the instructions on the label and spray it directly onto the leaves of your Dusty Miller plant.


Prevention is always better than cure when it comes to pests in your garden. Here are some tips to prevent slaters from infesting your Dusty Miller plant:

  • Keep the area around your Dusty Miller plant dry, as slaters like damp conditions.
  • Remove any debris or decaying plant matter from around your Dusty Miller plant.
  • Use mulch to keep the soil around your plant moist but not wet.
  • Keep your garden clean and tidy, as slaters like to hide in cluttered areas.


Are slaters harmful to humans?

No, slaters are not harmful to humans. They are just a nuisance pest that can damage plants.

Can I use natural remedies if I have pets?

Yes, most natural remedies are safe for pets. However, you should still take precautions and avoid letting your pets ingest any of the remedies.

How often should I spray my Dusty Miller plant?

It depends on the severity of the infestation. If you have a large number of slaters, you may need to spray your plant every few days until the infestation is under control. Once the problem is resolved, you can reduce the frequency of spraying to once a week or less.
