Hello,

Thanks for reaching out with your questions. I can address your questions related to bees and wasps, but birds are outside of my area of expertise.

I found cinnamon, clove, and peppermint, on the list of Exemptions for pesticides of a character not requiring FIFRA regulation. I did not see eucalyptus on the list, so I suggest reaching out to Michigan Department of Agriculture and Rural Development to see if eucalyptus can legally be used to deter deer. 

To prevent adverse effects on bees, I suggest keeping the products off of blossoms that bees are visiting. Keeping products of blossoms will likely help reduce bees contact and consumption of them. 

Thanks for caring about bees and birds!
