Title: Just-In-Time Learning Tools for Tick-bite Prevention Education

Abstract:

Currently, most tick-bite prevention education uses a “just-in-case” pedagogy – distributing brochures, community talks, social media – information delivered but not necessarily when it can or will be acted upon right away. What if more learning opportunities could anticipate, tailor, and deliver best practice information when people need to know it? This presentation will describe several “just-in-time” learning tools for disseminating tick-bite prevention information when people are more likely to practice it.

Title: Optimizing Tick Control Timing: Fall Applications of Synthetic Pyrethroids for Pollinator-Friendly Residential IPM

Abstract:

Traditional spring applications of synthetic pyrethroids target residential tick populations but may coincide with peak pollinator activity, raising concerns about non-target impacts. This study evaluates the efficacy of fall, post-frost applications of lambda-cyhalothrin—using both liquid (Demand CS) and granular (Demand G) formulations—on overwintering Ixodes scapularis populations across 70 residential properties. Treatments were delivered via high-pressure sprayers and backpack blowers in spring-only, fall-only, and combined spring/fall regimens. Results show that fall-only applications, particularly high-pressure delivery of Demand CS, achieved 94–100% reductions in host-seeking adult ticks and eliminated nymphs the following spring. These findings suggest that fall treatments can effectively target multiple life stages of I. scapularis while reducing exposure risks for pollinators and other beneficial insects. This approach supports a strategic shift in tick management timing to improve both efficacy and environmental safety. Long-term monitoring is ongoing to assess pollinator impact, compare natural alternatives, and evaluate environmental residue.

Abstract:

In 2025, legislation in Illinois expanded the authority of mosquito abatement districts to include tick surveillance and pathogen testing. In response, the Northwest Mosquito Abatement District (NWMAD) launched a tick surveillance program in fall 2024 and integrated tick education into its community outreach efforts. This program includes three major components: (1) systematic collection and identification of tick species across the district, (2) pathogen testing of specimens, and (3) public education on tick bite prevention and tick-borne disease risk. 

We conducted tick drags along 24 frequently used Forest Preserve District trails, with transects of 750 or 1500 meters and collections every 10 meters. Sampling occurred in fall 2024 (October–November) and spring 2025 (April–June). Ticks were identified by species, sex, and life stage, then preserved in ethanol. All Ixodes scapularis specimens were submitted to the CDC Fort Collins laboratory for pathogen testing via Next Generation Sequencing. 

In fall 2024, we collected 312 adult I. scapularis from 20 of the 24 sites. Of these, 136 (44%) tested positive for Borrelia burgdorferi sensu stricto, 12 (4%) for the human-active variant of Anaplasma phagocytophilum, and 8 (2.6%) for Borrelia miyamotoi. In spring 2025, we collected 348 I. scapularis, including 99 nymphs. Among these, 129 (37.1%) were positive for B. burgdorferi, 10 (2.9%) for B. miyamotoi, 12 (3.5%) for human-active A. phagocytophilum, and 4 (1.2%) for the non-human variant. 

Community outreach efforts have included distribution of tick identification cards, educational materials on disease symptoms, demonstrations of tick checks, and interactive activities such as using a stuffed dog to teach proper tick removal. NWMAD has presented these programs at farmers markets, school and library events, and community festivals. 

Our findings reveal unexpectedly high numbers of I. scapularis and notable pathogen prevalence in a region of the Midwest where tick presence has been underrecognized. Public engagement to date has highlighted a widespread lack of awareness about local tick populations, behaviors, habitats, and disease risks. Moving forward, NWMAD aims to partner with forest preserves to continue research on tick distribution and pathogen prevalence while expanding educational outreach to better equip the public with prevention knowledge.

Title: Beyond bites: Leveraging extension to address tick-borne diseases and investigate attitudes and opinions towards a Lyme disease vaccine

Abstract:

With tick-borne disease cases increasing across the United States, new communication approaches are needed to connect with at-risk audiences and inspire action. Pennsylvania has some of the highest case numbers of Lyme disease in the United States, and the spread of tick species into the state in recent years has led to new disease and pest management concerns. To address these needs, in 2019 Penn State Extension founded the Vector-borne Disease Team, a new program to bring vector-borne disease education, outreach, and applied research across the state of Pennsylvania via the University’s cooperative extension system. Since the founding of this team, members have delivered presentations and workshops across Pennsylvania, developed educational initiatives, and authored a variety of unique educational materials. Team members have also carried out distinct applied research and evaluation initiatives, including an investigation into current attitudes and opinions towards a Lyme disease vaccine. This presentation will cover the results of these ongoing extension, outreach, and applied research programs and how extension can be leveraged to address tick-borne diseases.

Title: Brown dog tick surveillance and Rocky Mountain spotted fever prevention in Arizona tribal communities

Abstract:

Although previously rare in Arizona, outbreaks of Rocky Mountain spotted fever (RMSF) transmitted by the brown dog tick Rhipicephalus sanguineus s.l. began in 2002 in communities with high populations of free roaming dogs. Our research and extension program explores both the current risks of RMSF transmission and works with affected communities to prevent disease transmission. 

One possible explanation for the emergence of this disease could be northward movement of the tropical lineage of the brown dog tick. Our research examined this possibility using sampling of current tick populations and analysis of ticks collected in the 1940s and 50s. Results indicated long-term presence of the tropical lineage in the state.   

Given its feeding preference for dogs and its ability to colonize peridomestic environments, the brown dog tick is best controlled by preventing tick infestations in dogs. Communities have developed several approaches to provide tick protection. We will review these practices as well as give results from a research pilot on the field efficacy of tick prevention.

Title: Insights from medical and veterinary professionals on ticks and tick-borne disease

Abstract:

The rising incidence and geographic spread of tick-borne diseases (TBDs) pose growing challenges for both human and animal health. This presentation synthesizes findings from KAP (knowledge, attitudes, and practices) studies conducted among healthcare professionals—medical clinicians and veterinary practitioners—to evaluate their understanding of local TBDs and identify opportunities for targeted education. The talk will cover insights into knowledge and practice patterns in low (Illinois) and high (the Northeast) Lyme-endemic areas, focusing on how, across the board, diagnostic awareness and perceived case frequency were closely linked to recent training and concern about TBDs. In published studies, recent education on ticks and TBDs was the strongest predictor of higher knowledge scores and more proactive diagnostic behaviors. Findings from these studies will highlight critical knowledge gaps across sectors and emphasize the importance of region-specific, continuing education initiatives. Strengthening cross-disciplinary training and surveillance efforts may enhance early detection, improve patient and animal outcomes, and support One Health strategies for managing the evolving threat of TBDs across the U.S.

Title: Importance of Haemaphysalis longicornis in Veterinary Medicine

Abstract:

Haemaphysalis longicornis (Neumann), the Asian longhorned tick, is a species native to East Asia, but invasive to Australia, New Zealand, and the United States. After being detected in New Jersey in 2017, it was rapidly spread across the US, because of its parthenogenetic reproduction, diverse affinity for host feeding and animal movement. As with many other ticks, it is an important One Health-associated ectoparasite, due to the array of pathogens that it can transmit and the production losses in farm animals. According to distribution models, H. longicornis has a wide range of suitable habitat in the US including western areas of the country. Educational, control and preventive methods are important tools to avoid disease transmission, animal infestations and further expansion in the country. Continuous surveillance and research studies will aid in understanding the biology, vector capacity and updated distribution of this tick.

Title: Alpha-gal syndrome: nuances of tick-borne allergy for an interdisciplinary audience
Abstract:

Alpha-gal syndrome is an allergy that has burst onto the scene of a field otherwise focused on infection: the field of tick-borne disease. Many of the techniques for prevention are the same, focusing on tick bite avoidance. Importantly, losing the ability to eat red meat is tangible and motivating – the public cares. Science communication is key, and understanding the nuances of alpha-gal syndrome is fundamental to building public trust and asking the right scientific questions. We all have important roles to play in the interdisciplinary approach to alpha-gal syndrome.
