Nova Scotia has a suitable climate for tick populations. Blacklegged ticks survive best in areas that provide a moist habitat (like wooded or forested areas, urban parks and gardens) because the trees provide shade, and leaves provide protective ground cover. Adult blacklegged ticks remain active until the temperature is consistently below 4°C.
Blacklegged ticks are found throughout Nova Scotia and all areas of the province are considered as having risk of Lyme disease.
