All of these insects build their nests in the ground and cause serious medical problems with their stings.
The first step in controlling wasps and hornets of this type is to identify them and find their nest, and every homeowner should be able to spot hornets’ nests for their family’s safety. Here’s how: Nests frequently show up in quiet, out-of-the-way places. Hornets are more active during the day and can be seen flying to and from a nest. Ground nests will have a small opening in the earth similar to a rodent or rabbit hole. Above ground, search common areas around the home such as overhangs, eaves of buildings, beams and supports, between studding and joists, and in garages, barns, and sheds.
These insects can be very dangerous; their stings send nearly half of a million people to the emergency room every year. If you can see a hornet’s nest, your best bet is to avoid it and make sure your family stays away as well. If the nest is near an area that the family uses a lot, such as a deck or patio, you should avoid using those areas during the day and make plans to have the nest taken care of.
