Spray Safe, Play Safe: Story-Based Films Increase Homeowner Confidence About Backyard Tick Management.

Lyme disease incidence is increasing in the United States despite myriad efforts to educate individuals about effective prevention practices to reduce exposure to nymphal Ixodes scapularis Say (Acari: Ixodidae) (blacklegged tick), the primary vector of the pathogen causing Lyme disease. Furthermore, Lyme prevention educational needs currently exceed the ability of public health professionals to deliver the information in person. Past work has shown there is especially high confusion regarding the use of acaricides for tick management by homeowners. Story-based education is known to engage individuals and change behaviors. To increase the reach and engagement regarding Lyme disease prevention practices, especially residential acaricide use, we created short, story-based educational films (Spray Safe, Play Safe) and evaluated their educational benefit with a survey pre- and post-viewing. We determined that after viewing the films, a significantly higher percentage of respondents reported increased confidence in identifying the riskiest areas in their yards for ticks, using personal protective measures to prevent tick bites, using tick-safe landscaping, and using tick control products. This study also suggests that using short, engaging films that can be posted to popular websites and social media outlets could be employed more frequently for successful and engaging Lyme disease education, as creative and up-to-date educational methods are needed.

Multistate Infestation with the Exotic Disease-Vector Tick Haemaphysalis longicornis - United States, August 2017-September 2018.

Haemaphysalis longicornis is a tick indigenous to eastern Asia and an important vector of human and animal disease agents, resulting in such outcomes as human hemorrhagic fever and reduction of production in dairy cattle by 25%. H. longicornis was discovered on a sheep in New Jersey in August 2017 (1). This was the first detection in the United States outside of quarantine. In the spring of 2018, the tick was again detected at the index site, and later, in other counties in New Jersey, in seven other states in the eastern United States, and in Arkansas. The hosts included six species of domestic animals, six species of wildlife, and humans. To forestall adverse consequences in humans, pets, livestock, and wildlife, several critical actions are indicated, including expanded surveillance to determine the evolving distribution of H. longicornis, detection of pathogens that H. longicornis currently harbors, determination of the capacity of H. longicornis to serve as a vector for a range of potential pathogens, and evaluation of effective agents and methods for the control of H. longicornis.
