Avoid bringing any food that’s sticky or covered in sugar. Not only do these become sticky without hand washing facilities but they can attract wasps. To keep hands clean, just pop some baby wipes in the bag and remember to pack an extra bag for the rubbish clean up at the end.
Insects can become a problem unless you pack accordingly. Ensure you pack insect repellent, or you can make your own with essential oils put into a spare spray bottle. Go for citronella, peppermint, tea tree and vinegar mixed in with water. Give it a shake before use and you’re good to go.
