Adding a few new plants to your garden could be well worth the effort.

Keep reading for a rundown of which plants repel fleas and where to put them around your home.

Flea-Repelling Plants

Many of the plants that repel fleas are fragrant herbs. If you have an herb garden you may already have plants that are protecting against fleas. If not, think about adding these plants to your yard.

Wormwood is an herb that is believed to be a powerful repellent for fleas.

Places to Put Flea-Repelling Plants

Around the Entrances –The front porch and back patio can be dressed up nicely and made more enjoyable when flea-repelling plants are around. Putting plants at the entrance of the home will also help to keep fleas outside where they belong.

Around the Home’s Foundation – Another way to keep fleas out of your home is by putting these plants near the foundation. Just steer clear of any invasive plants in this area.

Around Windows – Fleas can jump up to seven inches high. All it takes is a few jumps to get in windows. Try using window plants full of flea-repelling herbs to keep them out.

Anywhere Your Pet Wanders – Fleas love using animals as a blood supply. Controlling an infestation is often a matter of keeping fleas off your pets. That’s why you’ll want to add flea-repelling plants to the outdoor areas that you pets frequent most. HOWEVER – never put toxic plants in easy reach of animals. Never put any of the following in places where your dog or cat hangs out:

  • Citronella
  • Eucalyptus
  • Fleawort
  • Pennyroyal/Fleabane
  • Rue
  • Sweet Bay
  • Tansy
  • Wormwood

Put Invasive Species in Pots – Potted plants are great because you can move them around where needed. But they also work well for containing invasive plants like mint.

Planting flea repelling herbs and flowers is a preventative measure, but it isn’t a foolproof solution for keeping insects out of your garden, yard and house.  Regular pest control treatments are often the most comprehensive way of staying pest-free during the summer.
