With the wet winter that we have all had I look forward to the summer. But with all of the water, we will have mosquito heaven. This should help a little.
1 cup grated Castile soap
1/2 cup water
10 drops citronella essential oil
5 drops eucalyptus essential oil
1 T. dried, crushed pennyroyal leaves
Mix the ingredients into the melted soap/water mixture. With an
electric mixer,whip the soap until it has doubled in volume. Spoon the
soap into the prepared molds, pushing it into the molds the best you can
(the beating action cools the mix, so work quickly). If the mixture has
cooled off and thickened so much you can’t put it into the molds, hand
mold the soap into large balls.
