@IrishLass - I was wondering if you ever created a soap with catnip or other insect-repelling ingredients.Thank goodness that it is supposed to be effective against mosquitos in low doses (according to my research so far- 1% to 3%), and that the addition of other EO's such as the much lovelier smelling Lemon Eucalyptus greatly helps to tone it down.
According to my book Essential Oil Safety by Tisserand/Young, nepetalactone (the active insect-repelling component of catnip) can range anywhere from 12.7% to 84%. And according to a handful of corroborating sources that I've read so far, the catnip grown in colder regions/Canada is supposedly known for having the highest % of nepetalactone. For what it's worth, the one I bought from Liberty has 79.9%, if I am reading its CoA (certificate of analysis) correctly.

and if you did, if they were ever effective?
I hear that neem oil used in high percentages works as well.
