There are many species of bees, and virtually all are beneficial
through their activity as pollinators. However, since bees are capable
of stinging, they can cause a considerable nuisance problem. Bees, as a
group can be distinguished from wasps by the covering of dense, plumose
GROUND-NESTING BEES: Two
groups of ground-nesting bees commonly encountered in Michigan are
bumble bees and burrower bees. Bumble bees are easily recognized by
their large, robust, hairy, black and yellow (sometimes orange) bodies.
Bumble bees live in colonies of several hundred individuals; however,
only the queens overwinter. Burrower bees are small to medium-sized,
blackish or brownish bees withdensely pubescent heads and midsections.
Each female constructsa burrow in the ground and provisions it with
nectar and pollen.
Control of ground-nesting bees can be achieved by treating the nests
with an appropriate insecticide. For bumble bees treat the nest
entrance with carbaryl 5% (dust) or a "wasp and hornet" aerosol; after
treating, close the nest entrance with a handful of moist soil.
WOOD-NESTING BEES; Carpenter
bees and some leafcutter bees will nest in wood or in shingle gaps.
These bees can be controlled by injecting carbaryl 5% (dust), ready to
use diazinon or pyrethroid into the nest. After thoroughly treating,
plug the nest entrance with a dowel of the appropriate size or wood
