Things You'll Need
Instructions
Put on protective clothing and goggles in case the bees become aggressive. Scout your home and property and look for any bee activity or nesting.
Spray a quick squirt of a commercial bee killer into each hole you find. Since masonry bees are solitary, there will be only one larva per hole.
Seal up all cracks and crevices with caulk. This will ensure the larvae die as well as keep other bees from using this hole for future nesting.
Kill any remaining masonry bees you see with household insecticide. Remove protective clothing and goggles.
Plant some spearmint, thyme or eucalyptus around your home. The bees do not like the scent of these plants and will stay away.
