Viburnum plants are a great addition to any garden or landscape. They are easy to care for and offer beautiful flowers and foliage. However, like all plants, viburnums can become infested with pests, such as thrips. Thrips are small, slender insects that feed on the sap of plants and can cause damage to the leaves and flowers of viburnums. In this article, we will discuss how to get rid of thrips in viburnum plants.
The first step in getting rid of thrips is to identify the problem. Thrips are tiny insects that can be difficult to spot with the naked eye. They are usually less than 1/16 inch long and range in color from yellow to black. Thrips feed on the sap of plants and leave behind small, silver or bronze-colored scars on leaves.
If you suspect that your viburnum plant is infested with thrips, take a closer look at the leaves and flowers. Look for signs of damage, such as distorted leaves or flowers, discoloration, or silver or bronze-colored scars.
Once you have identified the problem, the next step is to remove any infested leaves and flowers from your viburnum plant. This will help prevent the thrips from spreading to other parts of the plant.
Use a pair of clean scissors or pruning shears to carefully cut off any leaves or flowers that show signs of thrip damage. Be sure to dispose of the infested plant material in a sealed plastic bag to prevent the thrips from spreading.
Insecticidal soap is an effective treatment for thrips on viburnum plants. It works by suffocating the insects and disrupting their feeding patterns.
To use insecticidal soap, mix it according to the manufacturer’s instructions and spray it onto the leaves and flowers of your viburnum plant. Be sure to cover all parts of the plant, including the undersides of the leaves.
Repeat this treatment every 7-10 days until the thrips are gone. Be sure to follow the manufacturer’s instructions carefully and wear gloves and protective eyewear when applying the soap.
Neem oil is another effective treatment for thrips on viburnum plants. It works by disrupting the thrips’ hormonal balance and preventing them from feeding and reproducing.
To use neem oil, mix it according to the manufacturer’s instructions and spray it onto the leaves and flowers of your viburnum plant. Be sure to cover all parts of the plant, including the undersides of the leaves.

Encouraging natural predators, such as ladybugs or lacewings, can also help control thrips on your viburnum plant. Ladybugs and lacewings feed on thrips and can help reduce their numbers.
To attract these natural predators, plant flowers that they are attracted to, such as daisies or marigolds, near your viburnum plant. You can also purchase ladybugs or lacewings online and release them near your plant.
