If you enjoy hiking, trekking, trail running, or spending time outdoors in and around Brasília, there is a good chance that sooner or later you may encounter ticks — particularly in areas surrounding Lake Paranoá.
One of the biggest contributors to the spread of ticks around the lake are the large populations of Capybara that inhabit the grassy areas near the water. While these animals are one of Brasília’s most iconic sights, they are also known carriers of ticks, so extra caution should be taken in areas where capybaras frequently roam or rest.
The most common tick species found in the Brasília region is the Amblyomma cajennense, commonly referred to as the Cayenne tick. Besides being unpleasant, ticks can also carry diseases, making prevention particularly important for hikers, pet owners, cyclists, and anyone spending time in tall grass or natural areas.
To reduce the risk of tick bites, it is highly recommended to use insect repellents containing 20–30% DEET. Products such as OFF! are widely available in supermarkets and pharmacies throughout Brasília and generally provide effective protection.
It is important to note, however, that while DEET-based repellents may remain effective against mosquitoes for up to 12 hours, their protection against ticks is significantly shorter — usually around 6 to 8 hours at most. For longer hikes or outdoor activities, reapplication may therefore be necessary.
A few additional precautions can also help minimize the risk of tick bites:
Avoid walking through tall grass whenever possible.
Wear long trousers and closed shoes when trekking.
Light-colored clothing makes ticks easier to spot.
Check your body, clothing, and pets carefully after outdoor activities.
Showering after returning home can help identify ticks before they attach firmly.
With a few simple precautions, it is still perfectly safe to enjoy Brasília’s beautiful outdoor areas, parks, lakeside trails, and natural landscapes.
