Chrysanthemums, or mums for short, are loved by gardeners and florists for their diversity of shapes and colors. But there’s another reason you should be planting them all over your garden: pest control! Chrysanthemums naturally produce a chemical called pyrethrin, and thanks to it, organic garden pest control can be as easy as scattering some mum plants.

Using Mums to Control Pests

Pyrethrin is the best of both worlds – it’s a neurotoxin that kills insects but does not harm mammals or birds. Insects prefer to stay away from it, so using mums to control pests can be achieved simply by planting them throughout your garden, especially close to plants that tend to be plagued by bugs.

To use a chrysanthemum for pest control, plant it about 1 to 1½ feet (30-45 cm) from the plants you wish to protect. If using mums to control pests so sporadically isn’t for you, try planting a row of them as a border – it should still do the job, but give your garden a more cohesive feel.

If you don’t have the extra room for all these chrysanthemums in your garden, plant them in containers and place them wherever they fit.

How to Make Pesticides from Chrysanthemums


If you want to take your organic pest control one step further, you can actually make pesticides from chrysanthemums. Simply pick the flowers when they’re at their fullest and leave them undisturbed in a cool, dark place with good air circulation until they dry. Grind them up into a powder and sprinkle it around your garden to kill and repel insects.

Another organic garden pest control can be made by steeping the flowers in hot water, allowing it to cool, and then sprinkling it on your plants. If this all sounds too intensive, there are commercial insecticides on the market derived from chrysanthemums. Buy yourself a bottle and fight off insects in a safe, organic, and biodegradable way.
