Researchers found that ticks continued to quest in woodlands throughout the year, even during the coldest months and ticks could also be detected on dogs throughout the year.
These observations concur with the results of a recent analysis of practice electronic health records which showed the presence of ticks on pets in all weeks between December and March2.
The study confirms the importance of treating dogs all year round to help reduce the risk of transmission of tick-borne diseases.
Lynda Maris, Product Manager for NexGard Spectra at Merial said: "It’s been thought for some time that ticks are very inactive or even dormant in winter and don’t present a risk. These findings show that they continue to quest in an attempt to find a host and are often successful. If ticks are attaching and feeding during the winter months, the risk of Lyme disease and babesiosis remains a real possibility. If the appropriate product is selected, the same year-round treatment programme that controls fleas and other parasites, will also treat ticks and thus help reduce the risk of tick-borne diseases."
The study recruited nine veterinary practices and monitored tick activity across three woodland sites in Southern Cumbria. In some cases multiple ticks were found on the animals – with one animal hosting an incredible 21.
Post graduate student Jessica Hall has been running the study since 2013, which has also involved running PCR for detection of DNA from Borrelia burdorferi (Lyme disease) on the collected ticks, with this data due to be released early next year. She said: "From the data we have collected in this longitudinal study we have identified questing ticks all year round at some sites and have shown that this pattern of questing activity results in pets being bitten by ticks even during winter."

Research on ovine parasite Toxoplasma gondii, carried out at the University of Salford, could have a significant economic impact on the sheep farming industry - potentially saving the lives of 5% of the UK lamb population.
Postgraduate student Emma Morley has been working as part of a large research team, looking at the importance of transmission routes of T. gondii (the cause of the disease toxoplasmosis) within different mammalian groups.
A scholarship from the Perry Foundation, which funds research benefiting the farming industry, allowed Emma to launch her own study at the School of Environment & Life Sciences.
Salford parasitologist Professor Geoff Hide said: "Emma's research may have some significant impacts on sheep farming. Nearly 5% of lambs are lost to Toxoplasma in the UK so it's of major economic importance as well as an important animal welfare issue."
He said that one of the key things Emma's research has shown is that the advice currently given to farmers may be causing an increase in the level of the disease rather than controlling it. "Farmers are advised to breed from ewes that have lost lambs to Toxoplasma but Emma's results show that what farmers should be doing is breeding from ewes that do not have the parasite," he said.
