NatureMetrics does not currently provide a kit for sampling faeces. This is a modified version of the protocol for bat dropping collection for DNA analysis from the Bat Conservation Trust – Bat Surveys for Professional Ecologists: Good Practice Guidelines (3rd edition).


Do not use the same sampling tools for different samples.

1. Using a permanent marker, carefully label a sterile tube (e.g. 1.5 mL tube) with a unique Tube ID.

2. Wearing gloves, use sterile tools (tweezers, spatula etc.) to transfer the faecal sample into the labelled tube. Avoid breaking the pellet upon collection. Fresher, intact pellets have a higher chance of success than older ones. If pellets are collected from single species roosts you can put multiple pellets into a sampling tube. Collecting multiple pellets improves our chances of species identification but is not prerequisite to our success. If it is a mixed species roost, put one pellet per sampling tube. If you are unsure, put one pellet per tube. Mixed species samples will be inconclusive.

3. Place the sample tube into a bag.

4. Use a new labelled sample tube and tools for each sample.

5. Once all samples have been collected, simply use the standard postal service with recorded delivery. Follow the packaging notes and send to: Nature Metrics, 1 Occam Court, Surrey Research Park, Guildford, GU2 7HJ, United Kingdom.


  • Ensure the box you are sending is in good condition and remove any old labels.

  • Avoid excess spacing by adding cushioning material (e.g. bubble wrap, newspaper) to avoid the product shifting inside the box.

  • Use good quality sealing tape and seal along box edges in a H pattern.

Important considerations for your sampling

  • It is the responsibility of the client to ensure that all efforts have been made to avoid contamination from external sources and between samples.

  • Handling samples without gloves can increase the content of human DNA, reducing data generation.

  • After sampling, movement of samples across borders without permission is not allowed as they are classed as biological samples.
