Blue winged wasps (or Scoliids): these guys are often seen flying in circles or figure 8s above the lawn. They are probably looking for grub worms in your lawn. If she finds one, she will sting it to paralyze it then lay an egg. The larva that hatches will feed on the grub worm larva. This natural grub worm control and is not noted to sting – unless you try to catch one.

Solitary bees: Several genera of these bees excavate holes in areas where the lawn is thin or there is little to no vegetation. Typically the female after excavating the hole will collect a large amount of pollen and deposit it within. There she lays an egg. The larva that hatches will feed on the pollen as it grows. Most of these bees are very valuable as pollinators of fruit and vegetable crops as well as flowers. Generally these only sting if provoked.

Cicada killer wasp: This one captures cicadas to serve as a food source for the next generation growing up in the hole where the paralyzed cicada is deposited. It looks imposing and the males may act aggressive. But the males do not have a stinger, and the females are seldom inclined to sting.

Some of the kinfolk can inflict a painful sting, however. A few suggestions on avoiding stings – notice if perfumes, sunscreen, hairspray, or other personal fragrances seem to attract them. Avoid areas where nests are known to be present. Watch for activity before pruning shrubs and look where you put your hands. When eating outdoors, keep food covered to the extent possible, especially sweets and meats. And inspect soft drinks carefully before sipping. It’s probably easier to tolerate a whining child who can’t have a soft drink than a screaming child who has been stung inside the mouth by a yellow jacket. Keep some distance from trash bins especially if beverage cans are present.

If you absolutely must kill a nest of bees, wasps, hornets, or yellow jackets: Use an insecticide intended for the purpose. Most insecticides will break down more quickly than the fuel or solvent you have nearby. “Wasp and hornet spray” is readily available in many stores.

For those who are allergic to stings, Do Not Attempt this yourself. Wait until almost dark when most of the residents are back in the nest. Wear long sleeves, long pants, and socks. Do not use a flashlight. Aim the spray at the opening to the nest and spray directly into the opening. Most residents will be killed on contact but be aware that some may try to get to you. Once you have finished, place an object such as a board over the opening and leave it. Most of the residents will be killed. In some cases a repeat application may be necessary.

Please remember that most of the bees, wasps, and other stingers fill an important role in our world. They don’t sting unless they feel threatened. You’re bigger than they are and your very presence may seem threatening especially around a nest. Avoid them if possible.
