Fleas are not welcome in a dog-friendly yard. Fortunately, there is an extensive list of flea control herbs to choose from. Many are poisonous, warns Vulcan Termite & Pest Control, so be judicious when deciding which to use. The safest include catnip, chamomile, lavender, marigolds, mint, and rosemary. Think twice before planting lemongrass, eucalyptus, ostrich and fleabane, rue and tansy.
Flea repellents can be strategically placed on a porch or patio and can be used to protect entryways. Vulcan touts them as window plants because the high-jumping flea can jump 7 inches off the ground.
Spraying your dog with essential oils is a proven way to keep him flea-free in your yard, recommends Jet Pet Resort, with the caveat to first ask your veterinarian to approve the contents. The preferred choice is a 6:4 solution of apple cider vinegar and water, with a pinch of salt. You can also use a flea collar on a dog. Sunlight is anathema to fleas, which thrive in a humid environment. To discourage insects, a dog-friendly yard should be well trimmed and weeded frequently. It should be kept dry and free of wet lawn debris. Jet Pet Resort also salutes flea-eating threadworms and helps keep a dog-friendly yard.
