I love the ideas and resources in this article for natural insect repellents. I also carry an effective essential oil-based version in my clinic for patients. In addition, thiamin supplementation does seem to help repel mosquitoes, but I haven’t noticed whether or not it would help for bees. Bees usually are not interested in stinging us unless they feel threatened. Wasps, on the other hand, start to get “grumpy” as summer progresses and can get quite aggressive. Let me know your thoughts on favorite repellents!!
