Ticks and mosquitoes may await the pandemic-weary seeking outdoor exercise
Pandemic-weary Americans have begun walking and hiking in recent months to get out of the house while avoiding infection with the novel coronavirus. At the same time, resource-strapped local health departments have been forced to divert money and people to covid-related activities, unwillingly creating openings for outside exercisers to get sick in other ways.

New records show spread of parasitic deer flies across the US
With flattened bodies, grabbing forelegs and deciduous wings, deer keds do not look like your typical fly. These parasites of deer — which occasionally bite humans — are more widely distributed across the U.S. than previously thought.

Tick Awareness and Prevention for Hunters
With an estimated 899 species of ticks world-wide—and over 90 different types within the U.S. —the odds of coming across one of these pesky parasites during a hunt are pretty high. While certain ticks are incredibly problematic for large ungulates—and have led to a massive decline in moose within New England and British Columbia—only a handful of tick species actually harm humans.

Asian tick that clones itself could spread fast and far in the US, study says
The Asian longhorned tick most likely began invading the United States years ago. Now found in nine states, the tick may soon occupy a large swath of eastern North America as well as coastal regions of the Pacific Northwest, according to research published Thursday in the Journal of Medical Entomology.
