White Spots on Thyme Leaves 

What are the white spots on thyme leaves? Many homeowners and gardeners who grow the plant notice white spots on their thyme leaves and wonder what they are. If that includes you, read on to learn more. 

The white spots on thyme leaves are an unfortunate yet common occurrence that you might run into each season. They are caused by leaf-sucking insects, including thrips, spider mites, leafhoppers, and whiteflies. These insects suck the liquid inside your thyme leaves using their needle-like mouths.  The end result is tiny white spots that form on the leaf surface. 

Nonetheless, the white spots should not be cause for alarm as they are harmless to the plant. The only problem is that they could affect the potency of your leaves and they may not taste the same they would otherwise.

How to Protect Your Thyme Leaves from Insects 

You can enjoy all the culinary, health and cosmetic benefits that come from thyme leaves by protecting your garden from the harmful insects. The leaves are naturally insect-resistant, but only to some extent.

So, what can you do about these bothersome insects? You can protect your leaves from the white-spot-causing insects using any combination of the following simple methods; 

  • Keep natural predators around that feed on the insects that cause the damage to your thyme leaves. Hummingbirds are one of many natural predators that can control the population of these insects.

Dragonflies, spiders, ladybugs, as well as lacewing larvae, are also helpful when it comes to getting rid of whiteflies, spider mites, thrips and leafhoppers in your garden. 

  • Do not use insecticides to get rid of these harmful insects. This is the number one mistake that many homeowners make in taking care of their garden.

Whiteflies, spider mites, thrips, leafhoppers and other white spot causing insects usually develop resistance to the insecticides that you use against them over time. Not only that, but the insecticides are not healthy to ingest when you finally do harvest and use your thyme leaves.

  • Set out index cards coated with a mixture of petroleum jelly and washing detergent to control the insects that are harmful to your plants. An equal mixture of these two substances is sticky enough to catch these pesky insects. 
  • Mulch using silver reflective mulch, especially when your garden is situated in a whitefly infested area. This is because the reflective mulch makes it difficult for the insects to find their host plants.



Now you know the cause of the white spots on your thyme leaves. You also know how to keep the spots from occurring on your leaves and have a healthier garden. It is time to make use of this knowledge, put it to use, and enjoy the many benefits that come from using thyme leaves in your everyday life.
