Tips to make a yard less attractive to ticks

Backyards are ideal places to spend warm afternoons soaking up some sun. Lazy days in the yard are a big part of what makes warm weather seasons like spring and summer so appealing. But those afternoons can quickly go off the rails when an unwelcome visitor makes its presence known.

Ticks are found throughout the world. However, the Centers for Disease Control and Prevention notes that only a select few types of ticks transmit bacteria, viruses, 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 Bourbon virus, Ehrlichiosis and, of course, Lyme disease, among others. 

Human beings can come into contact with ticks in most outdoor spaces including their own backyards. However, in order to evade these pesky critters, steps can be taken to make lawns less of a welcoming environment for 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 in Canada, where data from the Public Health Agency indicates human-reported Lyme disease cases increased from 144 in 2009 to more than 2,100 in 2022. Black-legged ticks do not like environments that are dry and hot, so short grass makes lawns less attractive to this type of tick. Some resources advise homeowners who have let their grass grow a little too high (around five or six inches) to bag their clippings when cutting the grass. Lots of clippings on the grass can provide a respite from the heat for black-legged ticks. 

• Create a tick barrier if your property abuts woods. Woods provide a cover from summer heat that black-legged ticks crave. So 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-repellent 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. 

These measures will not necessarily prevent all ticks from establishing themselves on a property, so individuals are urged to inspect their bodies and the bodies of their pets after a day in the yard.
