If you have a verbena plant in your garden, you may have noticed tiny grey bugs that roll up into a ball when disturbed. These little creatures are called slaters, also known as pillbugs or woodlice. While they are harmless to humans, they can cause damage to your verbena plant by feeding on its leaves and stems. Here are some tips on how to get rid of slaters on your verbena plant.
Before you start treating your verbena plant for slaters, it’s important to make sure that’s the problem. Slaters are small grey bugs that are about 1 cm long and have a segmented body. They are often found in damp areas, such as under rocks or in mulch beds. If you see these bugs on your verbena plant, they are likely feeding on the leaves and stems.
Slaters thrive in damp environments, so reducing moisture levels around your verbena plant can help deter them. Make sure the soil around your plant is well-drained and not waterlogged. Avoid over-watering your plant and allow the soil to dry out between watering sessions. You can also remove any excess mulch or debris from around the plant to reduce moisture levels.
There are several natural repellents that can keep slaters away from your verbena plant. One option is diatomaceous earth, which is a natural powder made from fossilized algae. Sprinkle a thin layer of diatomaceous earth around the base of your plant to create a barrier that slaters won’t cross. You can also use essential oils like peppermint, lavender or eucalyptus oil to repel slaters. Dilute a few drops of oil in water and spray it on the leaves of your plant.
If you only have a few slaters on your verbena plant, you can remove them by hand. Wear gloves and gently pick the bugs off the plant. You can then dispose of them in a bucket of soapy water, which will kill them. This method is time-consuming but effective for small infestations.
If natural methods are not effective, you can use insecticides to get rid of slaters on your verbena plant. However, be careful when using insecticides as they can harm beneficial insects like bees and ladybugs. Look for insecticides that are specifically designed for slaters and follow the instructions carefully.
