Perhaps the pest group that generates the most fear and anxiety in people, and for good reason. Stings from these pests can be fatal to those individuals that are allergic to them. Even if you’re not allergic to them, the stings hurt!
Small colony wasps build open-comb nests where you can see the cells. They build them in sheltered areas such as soffits, under decks and furniture, under or in railings, lights, behind shutters, vents, gazebos and anywhere else they can be protected from the elements. They can be very aggressive when disturbed.
Yellow Jackets are a large colony wasp that prefers to nest in cavities in the ground or buildings. Peak activity is usually seen in July and August, and it is not uncommon for those nesting in a building cavity to break through drywall into living areas. This breakthrough is usually preceded by a “wet spot” on the drywall, accompanied by a “rice crispy” crackling noise. Yellow Jackets will aggressively defend their nest.
Cicada Killer Extermination
The most common solitary wasp in this area is the Cicada Killer. This large, almost 2″ long, black and yellow wasp can be seen swarming around lawns in mid-summer. They prefer to build nests on sunny hillsides. Nests are burrows dug into the ground, and large (6″) piles of excavated soil are visible near the nest entrance. While their size is intimidating, like most solitary wasps and bees, Cicada Killers are docile toward people and pets.
Bald Faced Hornet Extermination
The nest of the Bald Faced Hornet is a grey paper “ball” which is most often seen hanging from the limb of a tree, but, they also can attach nests to soffits and siding of buildings. They have an extremely aggressive nest defense trait and have been known to attack just because you’re within several feet of the nest.
These whoppers reach their peak in May. Carpenter Bees are large, black & yellow bees that resemble Bumble Bees. They are most often seen hovering near their nesting sites such as decks, soffits, facias or other parts of the home with exposed, unpainted wood. The female builds her nest by boring a virtually perfect ½” hole is the wood and then turning in the direction of the wood grain. She bores the tunnel several inches long and then divides it into multiple chambers, with an egg and pollen mixture in each chamber. A large pile of ‘sawdust’ or frass is usually seen below the entrance to the nest.
Fecal staining, a yellowish-brown substance, can also be found on siding or windows in an inverted ‘V’ shape pointing to the nest.
Carpenter Bees are NOT aggressive. In fact, the males do not even have stingers. But, they are curious and will hover around you! Successful treatment of this pest requires application directly into the nest whenever possible. PAINTING the exposed wood with latex or oil based PAINT (not Stain) can help to prevent a reinfestation.
