They recommend the use of bug spray to dissuade the pests from latching onto you.\nBut this isn't the only area. Most of the province has favourable conditions for deer ticks to live in, Public Health Ontario (PHO) reports.\nThis is because of the plentiful bushy and wooded areas, which they love.\nEvery year, #MLHU is finding more and more blacklegged #ticks. That’s why a large portion of London and @CountyMiddlesex is now identified as a Lyme disease “risk area” by @PublicHealthON. More blacklegged ticks = a higher risk of #LymeDisease. /1 pic.twitter.com/07M0xUOePh— MLHealthUnit (@MLHealthUnit) August 19, 2020\nAccording to a map released by PHO, areas such as Kingston, Mississauga and Hamilton are also considered to be high-risk areas for Lyme disease.\nTurkey Point and Niagara are also places where you should be on the lookout for these pests.\nPublic Health Ontario\nHowever, it is good to note that these bugs are more likely to be encountered in nature instead of in paved spaces."If there are no wooded or brushy areas present within a section of the indicated risk area (for example, a parking lot), it is expected that blacklegged ticks will not be present," PHO wrote.\nIf you do find a tick on you, it is important to remove it with tweezers as soon as possible. "Removing ticks within 24 hours usually prevents Lyme disease infection," says MLHU.
