Bless your heart... We have a problem with Red Wasp!
DH was hit 5 times on the top of his bald head last summer. I actually had to take him for a steriod shot becuase of all the Red Wasp bites/stings were causing a problem with his swallowing...
This year one hit him on the top of his ear... He looked like a wrestler from the 1970's after a hard pounding!
We didn't think that Red Wasps would cause such a health concern, but apparently they do and can!
We declared war on the darn things. They were found everywhere... Under the pool deck, in the dog house for the timer for the pool, in the eves of the house and in the vent for the camper trailer. These flying meanies were just about everywhere chasing us down!
The nest we found in the eve behind a board was the size of a large orange. Since we couldn't douse the house in gasoline, we emptied a large can of wasp killer on the nest until the flying ones died and knocked the nest out with a broom.
Every summer since, we fight Red Wasps and every year we buy more wasp spray and have a can handy when we are working outside.
Make sure to read the can of spray you are using to make sure it covers that type of flying critter... Use the whole can if need be and wear protective clothing when hunting them down. Be very watchful of where they are coming from... get them before they get you...
Good Luck!
