Tis the season for cicada killers, the large wasp that looks as if you can saddle and ride it into town. Cicada killers over winter int he soil and emerge around this time of year, late June or early July. These ground nesting bees are no doubt intimidating and if you are unfortunate enough to have many of these bees infesting one area you may want to consider calling in the pros to treat the area. They may spray the wasps directly or they may dust the holes with an insecticide dust. If there are only a few wasps and they are not in the way, then I would leave them alone, maybe they will help limit that crazy noise the cicada makes all summer, although, after this years world cup and the horns that accompanied it, we may be used to crazy sounds.
