Backyards are ideal places to spend warm afternoons soaking up some sun. But those afternoons can quickly go off the rails when an unwelcome visitor makes its presence known.

Ticks can be found throughout the world, but the Centers for Disease Control and Prevention notes that only a select few types of ticks transmit bacteria, viruses and parasites, or pathogens, that cause diseases in people. But even if the number of tick species that transmit diseases to humans is relatively low, ticks that can infect humans are a notable threat. Such ticks carry pathogens that the CDC notes can cause a number of diseases, including Lyme disease, among others.

People can come into contact with ticks in their own backyards. But they can take various steps to make lawns less welcoming to ticks.

— Cut your grass short and keep it that way. Black-legged ticks are transmitters of Lyme disease, which the CDC notes is the most common vector-borne disease in the United States. Lyme disease also poses a growing threat. They do not like environments that are dry and hot, so short grass makes lawns less attractive to this type of tick. Consumer Reports advises homeowners who have let their grass grow a little too high can provide a respite from the heat for black-legged ticks.

— Create a tick barrier if your property abuts woods. Properties that abut the woods may be more vulnerable to these unwanted guests than yards that do not border woodlands. A barrier of dry mulch made of wood chips between a property and a bordering wooded area can help repel ticks, who won’t want to settle in often dry, hot mulch beds.

— Plant with infestation prevention in mind. Some plants can help to repel ticks because they boast certain characteristics that ticks cannot tolerate. The fragrances, textures and oils of plants like garlic, mint, lavender, marigolds, and others create less welcoming conditions for ticks. Homeowners can speak with local garden centers for advice on tick-repellant plants that can thrive in their particular climate and on their properties.

— Remove yard debris. Piles of wood, leaves and brush can make for good conditions for ticks that transmit disease. After raking leaves and gathering brush, discard the resulting piles immediately.
