Quick Answer
Cave insects can be a significant concern when entering a cave, especially in areas with high humidity and darkness. They can carry diseases such as histoplasmosis and cryptococcosis, and their bites can cause skin irritation and allergic reactions. Insect infestations in caves are often worst near shelter rock outcrops.
Cave Insect Ecology
Cave insects thrive in areas with high humidity and temperatures between 40-60°F (4-15°C). Shelter rock outcrops provide ideal conditions for insect infestations, as they can harbor moisture, food sources, and shelter. Insects such as bats, spiders, and cave crickets can be found in these areas, and their populations can be dense.
Insect-Related Hazards
When entering a cave with a shelter rock outcrop, be aware of the potential for insect-related hazards. Wear protective clothing, including long-sleeved shirts, long pants, and a face mask to reduce exposure. Use insect repellents containing DEET, picaridin, or oil of lemon eucalyptus to deter insects. Avoid sudden movements, which can provoke insect attacks.
Identification and Safety Precautions
To identify potential insect threats, look for signs of infestation such as insect droppings, eggs, or webs. If you encounter insects, slowly and calmly back away while maintaining a safe distance. Avoid touching or handling insects, as this can cause them to become aggressive. If you experience allergic reactions or symptoms of disease after entering a cave, seek medical attention immediately.
