No bug spray in the forest? Here’s an ancient and surprisingly effective trick our ancestors used: 1️⃣ Place a damp cloth directly on an anthill and leave it for 1–2 minutes. 2️⃣ The ants will try to defend their home and spray the fabric with formic acid — their natural weapon. 3️⃣ Once the cloth is soaked, shake off any remaining ants. 4️⃣ Then rub the cloth on your clothing — or even your skin (only if you’re sure you’re not sensitive or allergic!) The fabric will have a sharp, vinegary smell
