How to Get Rid of the No See Ums (Purrujas) in Monteverde During Green Season
Monteverde, Costa Rica, is a haven for nature lovers, but the lush, humid environment that attracts so many visitors also brings some unwanted guests—no see ums, locally known as purrujas. These tiny but persistent pests are particularly active during the green season. This guide will help you understand no see ums and provide effective strategies to keep them away from your home.
Understanding No See Ums (Purrujas)
No see ums, or Ceratopogonidae, are small flies also known as biting midges, sandflies, punkies, and sand gnats. These pests, measuring between one and three millimeters long, are notorious for their itchy and uncomfortable bites. In Costa Rica, they are commonly referred to as purrujas.
Characteristics:
- Size: 1-3 millimeters
- Bite Marks: Small clusters of red dots that can expand into large, itchy welts
- Active Season: Green season (rainy season)
Why Purrujas Thrive in Monteverde During Green Season
Monteverde’s green season, with its high humidity and frequent rainfall, creates the perfect breeding ground for purrujas. These pests breed in wet sand and thrive in humid environments, making gardens, ponds, and other damp areas ideal habitats.
How to Identify Purruja Bites
Purruja bites appear as small clusters of red dots on the skin, which can develop into large, itchy welts. Unlike mosquito bites, purruja bites can be more severe and last longer, sometimes up to two weeks.
Strategies to Get Rid of No See Ums (Purrujas)
1. Close Your Doors and Windows
During the green season, keep your doors and windows closed to prevent purrujas from entering your home. This simple step can significantly reduce the likelihood of an infestation.
2. Install Mesh Screens
If you prefer to keep your windows and doors open, install fine mesh screens. These screens act as a barrier, allowing fresh air to circulate while keeping purrujas out.
3. Keep Your Home Cool
Purrujas are attracted to warm body temperatures. Use air conditioning to maintain a cooler indoor environment, deterring these pests from entering your home.
4. Use a Dehumidifier
Invest in a dehumidifier to reduce indoor humidity. Purrujas thrive in humid conditions, so lowering the humidity in your home can help keep them away.
5. Employ Essential Oils
Essential oils like lemon, eucalyptus, mint, and camphor are known to repel purrujas. Create a DIY spray by mixing these oils with water, or purchase a natural insect repellent containing these ingredients.
6. Set Up CO2 Traps
Purrujas are attracted to carbon dioxide. Use CO2 traps to lure them with the promise of a blood meal, only to trap them using a vacuum or adhesive mechanism.
7. Maintain Your Yard
Keep your yard tidy by regularly mowing the lawn and trimming bushes and shrubs. Lush vegetation can attract purrujas, so maintaining your outdoor space reduces potential breeding grounds.
8. Fix Leaks
Eliminate any sources of moisture in your yard and home by fixing leaks in drains, pipes, hoses, sprinklers, and faucets. Reducing these wet areas can prevent purrujas from thriving in your environment.
9. Reduce Outdoor Lighting
Purrujas are attracted to light. Minimize outdoor lighting and close blinds at night to avoid drawing them towards your home. Consider using bug-repellent light bulbs like compact fluorescent lights, sodium vapor bulbs, or halogen lights.
Preventing Purrujas in Monteverde
Preventative measures are crucial in keeping purrujas at bay during the green season. Remove all sources of moisture around your home and take steps such as screening windows and doors, sealing gaps around eaves, and spraying pesticides before the peak season. By staying proactive, you can enjoy a purruja-free environment.
