It's tick season: Learn to protect yourself and your animals with free webinars

To educate the public about tick risk and tick bite prevention in these companion animals, Penn State Extension will offer the spring 2022 “Tick Webinar Series.” The vector-borne disease extension team will hold three webinars in May — Lyme Disease Awareness Month — at no cost to participants.

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.

Ticks - biology, threats, protections - are focus of 10-week Penn State webinar series

Ticks, Lyme disease, other tick-borne diseases and Pennsylvania’s No. 1 position in all of that will be explained in detail in a free, 10-part webinar series from Penn State Extension that begins Thursday, July 9, with weekly installments scheduled through September 17.

Parasitic Deer Fly Now Spreading Across US Says Study

Entomologists from Pennsylvania State University found that deer flies, which sometimes bite humans, are more prevalent in the United States than originally thought.

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.

Pa. Lyme disease cases appear to hit plateau, but that shouldn’t change your outdoors routine

There’s good news about Lyme disease, Pennsylvanians. After a couple of years of leading the nation in “confirmed and probable” cases of the tick-borne disease, the experts expect the number of cases to level off.

Institutes of Energy and the Environment announces seed grant recipients

Several Huck researchers are among the recipients of 2018-19 IEE seed grants.

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.
