Safety instructions for staying and working at Yuyo S.R.L.
🔒 Safety Guidelines for Volunteers at Yuyo
Welcome to Yuyo – a place of biodiversity, learning, and shared responsibility. We live on the edge of the jungle, and with that comes beauty, but also risks. To ensure your safety and well-being, we ask all volunteers to carefully read the following guidelines.
🪴 1. Plants
Some tropical plants are inedible, toxic, thorny, or can cause skin or eye irritation.
- Do not eat or touch any plant you don’t know.
- Wear gloves when handling thorny or irritating plants.
- Machete work: Gloves are optional. Only use them if they fit well. In many cases, bare hands offer better control.
- Safety goggles are recommended when cutting shrubs that release sap.
Gloves and goggles are available. Please ask.
🐜 2. Animals
🦟 Insects
- Dengue is a real risk in the region. In 2023, 6 people on the finca were infected simultaneously.
- Use repellent, wear long clothing if needed, and sleep protected.
- Leishmaniasis exists in Costa Rica but is very rare in our area.
- Ticks are uncommon but possible – check after working outdoors.
🐜 Ants
- Bullet ants: Two nests on site. Not aggressive unless stepped on or grabbed. Painful but not dangerous.
- Driver ants: Visit every ~3 months, swarm through houses for a few hours. Stay calm and move to an unaffected area.
🕷️ Spiders
- Golden silk spiders are harmless, but don’t inhale web fibers.
- Phoneutria (wandering spiders): Seen every 2–3 months. If sighted:

- Do not approach. Call us – we will relocate them carefully.
- If bitten (hasn’t happened here, but to a neighbor), we will help you reach a hospital immediately.
- Tarantulas: Rare. We gently remove and relocate them with a bucket. Let us know if you see one.
🐍 Snakes
- Fer-de-lance (terciopelo) is the most common venomous snake in Costa Rica. We’ve had 3 sightings inside buildings.
- Coral snakes and boas have also appeared, but moved on peacefully.
- If you see a snake:
- Do not approach. Inform us immediately.
- If we are not around: keep a safe distance.
In case of a bite: remain calm, wash the wound, immobilize the limb, and get medical attention immediately. Do not cut, suck, tourniquet, or give alcohol.
🥾 3. Terrain
The terrain can be steep, slippery, and overgrown. Hidden holes or debris from previous owners may cause tripping hazards.
- Wear sturdy boots or rubber shoes.
- Watch your step and ask for help if you’re unsure about certain areas.
🛠️ 4. Construction Zones
- Do not enter marked-off areas under repair.
- Report any damage or signs of termites.
- Some wooden floors may become unsafe quickly – be attentive.
⚙️ 5. Tools & Machines
- Do not use machines without training or permission.
- If you have experience, let us know and we’ll assess together.
- The tool room is open – ask before using anything.
🔪 6. Machete Use
- Briefing required before use.
- Gloves optional (see section 1).
- Always clear your surroundings.
- If you don’t feel comfortable: no problem, there are many other tasks.
🔥 7. Fire Safety
- Fire extinguishers are installed in multiple locations. Please learn where they are.
- No open fires without permission.
- In case of fire or smoke: stay calm, evacuate, and alert us.
📌 Final Notes
- These instructions are based on experience and updated regularly.
- Nature is unpredictable – ask if you feel unsure.
- You’re never required to do anything you’re uncomfortable with.
