When wasps build nests where we don't want them, we spray the nest with water. The reason wasps build nest under eaves and porches (and light fixtures) is because these places are sheltered. If they keep getting wet, they'll abandon the nest and find a more suitable place. I don't know a lot about light fixtures, but can imagine that where the wires are, they will crawl through those small spaces.

Don't feel silly. How could you have known? By the way, look around at the wooden surfaces that surround you when outside. If you see any perfectly round holes, you'll know that a female bee has been at work. The holes will be large enough for you to insert a finger. If you happen to see a BUNCH of these holes, then I'd call your landlord again. Carpenter bees, in large numbers, can weaken outdoor structures. For every bossy male you encounter, there is a female (unusual in the insect world) mate. That female is capable of drilling several holes into which she will deposit one egg. I love the one or two that we have every year. They are so much fun to mess with. Sheesh, what an attitude! "Hey, you wanna piece of me?"

You guys got off easy ! These are THE most vicious of all bees I have encountered in my years. I ran over a nest once with a bush hog and got 26 stings all over every exposed area until finally outrunning them. They are super aggressive. I do not know their official name but I call them ground bees or yellow jackets. They typically occupy abandoned mole tunnels. Usually they get stirred up and many of them find you before you realize they are even around. Not only vicious they sting many times and keep on stinging. My solution has worked every time: pour about 1/4 pint of gasoline in the hole from a narrow neck bottle or some handy spouted container. Then toss a match onto it. The result is not what you might expect. There is a flame 6" or so high that just burns for quite a while. The vicious $%^& try to fly back in the hole and most are burned in the attempt. The ones inside never make it out. A day later none will be found. I agree with others that bug spray is useless except for 1 or 2 caught alone.

You saw that program too! It was interesting. Yes, I've read where fireants will attack termites and you won't have any fleas and ticks around either. I haven't kept up with the latest on it, but an accidentally imported Formasa termite is eating the south I hear. I wonder if the fireants might be making a dent in them. Maybe they need that African grandfather to come over and show them how it is done! LOL Speaking of eating the south -- the imported Kudzu vine "the vine that ate the south" also has its natural control -- a certain caterpillar, but it also eats soy beans so the soy bean farmers won't allow it to be imported. Fireants have their predators too. There is a certain fly that preys ONLY on fireants in Argentina, the native habitat of fireants, and that's what keeps them under control there. I watched a TV program last year on how they are breeding the fly in U.S. labs to help combat the fireants. They were afraid the fly was more cold sensitive than the fireant, but on the first trials the fly did survive the winter in the area in which they were released. Another problem was keeping the ranchers from poisoning the fireants and the fly along with it. So they invited several big ranchers to the lab to demonstrate how devastating the the fly was to the fireant and the ranchers were convinced and allowed trials to be held on their ranches. This was a couple of years ago and I don't know how that's coming along. Yes, many insects have a larva (worm) stage they go through. You have to give the social insects, like bees, termites, and wasps, a little credit for the long term care they give to their little ones -- even though their face is one only a mother could love. :-) Happy gardening -- insects and all!
