How does citronella work in the Bioethanol fireplace?
Bioethanol Fireplace Fuel Citronella repels target pests rather than killing them. It works by masking scents that are attractive to insects. Burning of the fuel in an outdoor firepit releases and creates an invisible barrier of citronella within the general area of the firepit. Insects find this barrier and the smell of citronella unappealing and as a result find it difficult to locate their target to feed. It is also thought that citronella may also work by masking odours attractive to pests. However, this thought has not been confirmed by official scientific study.
