As summer approaches and we all start having to deal with bugs. Do you want to know what to use for your very own insecticidal soap recipe?

Citronella and lavender soaps have very good insect repelling properties and very good stay power even though they are in a wash off product like a soap.

Lavender EO is characterized by a camphor content upward of 8%. Camphor is the sharp, ‘mothball’ element of the fragrance – not desirable for perfumery, but not necessarily bad in soap. It also explains why lavender has a long use as an insect repellent.

Fragrant soaps often attract annoying bugs. But this bugs be gone soap, while smelling quite pleasant, repels bugs. Using this soap will not eliminate pesky insects, but it will make you less appealing to them.

Other Insect-Repelling Essential Oils You Can Use

  • Geraniol. Geraniol Acetate, Limonene, Camphene – primary constituents of Citronella
  • Terpinene-4-ol, Cineol, Pinene, terpinenes, cymene, sesquiterpenes, sesquiterpenes alcohols, etc. – primary constituents of Tea Tree
  • Linalyl Acetate, linalool, lavandulol, lavandulyl acetate, terpineol, cineol, limonene, ocimene, caryphyllene, etc. primary constituents of Lavender
  • Eucalyptus, Lemon – Lemon type for insect problems
  • Catnip –one of the best repellents but rather expensive still, a little goes a long way.
  • Cedarwood, Virginia – mixed with citronella and lavender it was the primary ingredients in most bug sprays prior to the incorporation of DDT in more modern insecticides.
  • Pennyroyal – minty and herbaceous and a known insect repellent
  • Lemongrass – also a decent choice for a repellent although not a primary ingredient
  • Neem (the essential oil not the carrier oil although the carrier oil does have these properties too)
  • Patchouli – used for centuries to protect Persian carpets from insect infestation also a good base for the blend as most all others are top notes.
  • Rosewood – very similar to lavender in chemical composition but can add a bit of a floral woody note to blends, also a good base not in a blend

This is not a formula and each of these should be investigated and studied for use percentages but it is a good starting place on a blend for this purpose.

Once you formulate the blend you can put it into an alcohol or cyclomethicone (one or the other, they don’t mix) and apply as needed. You can also make a cream or lotion or even a soap with the blend.
