I am apparently not alone in thinking that advice to save pollinators (let your lawn grow) clashes with advice to avoid ticks around the house (cut the grass short because ticks don’t like heat and dryness).
But a (admittedly, very preliminary) study says that maybe they don’t clash, as reported by the U.S. Forest Service:
As part of a study to evaluate whether less frequent lawn mowing in residential lawns in Springfield, Mass., could promote floral resources and hence, serve as viable habitat for native bees, Lerman and her partners surveyed for blacklegged ticks (Ixodes scapularis, also known as deer ticks) as well as bees every three weeks. In 16 suburban Springfield lawns over the course of two summers, Lerman and colleagues documented 111 bee species, which equates to roughly one-quarter of all bees documented in Massachusetts. As for blacklegged ticks? In 144 tick drags in lawns of various lawn mowing frequencies and grass heights, Lerman and her colleagues found not a single one.
Here’s the important point:
While blacklegged ticks are no doubt lurking in people’s yards, D’Amico said that the grassy part of a property is probably too dry for the tick. “This species needs near 100 percent humidity for at least part of the day,” D’Amico said. “Where we have leaf litter, the ticks do very well.”
