Insects can be a nuisance, whether you’re spending time in your garden or trying to keep your home pest-free. Fortunately, many flowers not only add beauty to your garden but also serve as natural repellents for bugs. By planting specific flowers, you can create a more comfortable and bug-free environment. This article will introduce you to the best flowers to plant to keep bugs away and provide tips on how to make the most of these natural pest deterrents.
Why Do Some Flowers Keep Bugs Away?
