Yard treatments

During 2019, we worked with two communities in Wisconsin to test a lawn treatment that many people use to control grubs to see if it was also effective in reducing deer ticks.  We treated a narrow strip between the yards and adjacent woods in May and then measured tick density at the edge of the woods and a few feet into the yards for up to 4 weeks after treatment (through the peak of the nymphal season).  The treatment resulted in a high level of  reduction of nymphal ticks in the lawn areas in comparison with yards that received only a water treatment.  If you already control for grubs in your lawn, this may be an added benefit.
