Multicolored Asian
Lady Beetles
The shorter days and
cooler temperatures combined with the senescence of the soybean
crop will have the multicolored Asian lady beetles leaving their
summer feeding sites to seek protected overwintering locations
this fall. Soybean harvest tends to kick the migration into high
gear. more...
Earwigs
We’ve gotten quite a few calls from homeowners this summer who
are concerned about the 1/2 to 3/4 inch long light red-brown to
black insects with the forcep-like appendages (pincers) sticking
out of the back end. Most suspect that they are some kind of
cockroach when they find them inside but actually they are
something quite different and do not pose a threat to humans or
animals. These insects are called earwigs. They are favored by
the wet conditions (when it is hot and dry these conditions are
created artificially by watering). Even though they may have a
frightful appearance, move rapidly around baseboards at the
ground level, and emit a foul-smelling, yellowish-brown liquid,
they aren’t trying to live in your hair or get in your ears.
Earwigs are rapid runners and feed on mosses, lichens, algae,
fungi, insects, spiders and mites. They require moist, cool
places and are found in damp crawl spaces, flower gardens near
the home, in mulches, compost piles, trash, under boards and in
wood piles. During dry, hot weather, earwigs sometimes migrate
indoors. After entering houses, they feed on sweet, oily or
greasy foods or houseplants. Earwigs need and are very attracted
to moisture. They are also attracted to lights.
The best indoor control program starts by addressing the
environment outside the home. Dry the area out around the
outside of the house if practical. Since they are active at
night and are attracted to lights, reduce lighting around doors,
windows and other potential entry sites. Replace worn weather
stripping and caulk and seal cracks and crevices that can allow
them access indoors. Once inside, earwigs can be easily killed
by insecticide treatments aimed at cracks and crevices, along
baseboards, beneath cabinets, along door and window sills and
other daytime hiding places. For more information please contact
the Minnehaha County Extension Office at (605) 367-7877 or by

Soybean Aphids
 Soybean
producers [should} be especially vigilant now in scouting and
taking action against soybean aphids because
most soybeans in this area are in full bloom or R2 stage.
Soybeans that are entering the crucial reproductive stages need
to be protected from insect pressures.
