The Southern Home Bestuary: Living with our critter friends and enimies.

The 17-year cicada showing its distinctive red eyes.

  From the Piedmont of Virginia through the Carolinas into Georgia and on west to Arkansas,  Brood 19 of the 17-year cicadas are emerging by the millions for their brief above-ground stay. For about two weeks they sing their “hearts” out.  Actually they do not sing with their hearts, but once the southern woods warm up they put out an almost mechanical-sounding buzz,  like a piece of heavy machinery,  that can reach a noise level of 100 decibel. Seldom does only one sing. More often  it is thousands of them that get cranked up in their enthusiastic efforts to attract a willing mate. The numbers of these insects can be staggering, with up to 1.5 million per acre.

 They emerge, climb a vertical surface and then molt. Initially they are  ghostly white but ultimately harden into darker brown and yellow hews. The distinctive red eyes distinguish these from the common, or annual, cicadas. They may feed extensively enough to damage young shrubs, but mature trees are almost always able to withstand even heavy feeding without damage.

 Wild turkey’s enthusiastically feed on this bounty of free crunchy protein, as do many small mammals. Although big and noisy, their mouth parts are not suitable for biting. The enormous numbers of them insure that a sufficient number will survive to bring on the next brood.    

  Once mating takes place, eggs are laid, pupate and then fall to the ground where they spend the next 16 years about a foot below ground feeding from juices extracted from plant roots.

Carpenter ants and their nesting cavity exposed in a cut, fallen limb

  Carpenter ants are large, black,  scary looking; but are more valuable as an indicator of water damaged wood inside houses than they are trouble. These ants live and forage outside and will most frequently be seen on and around old trees. Although they can bite, they are not aggressive towards man as are other ant species such as the fire ant.

This small hole in a pecan limb provided entry to a nest containing hundreds of carpenter ants.

  In any southern environment where there are mature trees, there will be sufficient cavities to support a thriving population of carpenter ants. However, when these ants start being spotted indoors or going into structures, this means that there is wet wood where they are nesting.  By the time ants appear, termites have also usually been active for some time. Very often this means that structural damage has already been done by termites and treatment and wood replacement will be necessary.

  One carpenter ant spotted inside a house is not a particular cause of alarm; but when these start to be seen regularly inside a house or apparently going in and out, immediate corrective actions need to be taken.

Spiders                                 Transplant when must                                   Largely ignore 

Common Garden Spider

  Spiders have an adverse psychological impact on many people. With the exception of two species in the Southeastern U.S., they represent no real danger; although all spiders kill with venom which can sometimes cause septic wounds in people and occasionally be deadly. One thing that spiders know very well is their typical prey, whether they catch it in webs or stalk it like wolf spiders. Humans are too big for spiders to consume and , unless they feel a need to defend themselves, they will save their venom for something they can eat.  More people are likely injured attempting to escape from harmless spiders than are bitten by them. 

  A systematic count of species in and around Whitehall  would likely turn up more than 20 varieties. The largest is the common garden spider shown in the photo. This is an exterior web-spinning spider. Once it finds a spot where it can catch insects it will tend to stay in that area all Summer. The individual shown is about 2-inches long. They will increase body size during the summer, but not grow significantly in over-all length.  The largest North American spiders are the tarantulas which are native to the Desert Southwest and are seen in Georgia only in pet stores. 

  Even the largest spiders will only bite man when provoked. I do have to be careful of black widow spiders when working near wood piles, inside sheds where there may be piles of old boxes, or even under the house. If I disturb their homes, spiders will sometimes bite. I can’t say that they make a direct link between me and their environment  being moved around; but a bite can result.  These bites can make an adult  ill, and a few people who are susceptible may even die from a black widow’s bite, although this is an unusual event. I have never been bitten. 

  Many insects bite, and spiders often get the blame for unexplained bites caused by bed bugs or other pests. When webs in the corners of the ceiling get too big, I sweep them down. Mostly  I let spiders “do their thing” and hunt some of the household insects. I will occasionally rescue a spider who gets trapped in a tub or sink. The way to do this is to fold up a cone of paper,  let it scoot inside, close the cone and release it outside.  They are too fragile to attempt to pick up by the legs. 

  After nightfall on a Summer evening, take a flashlight and walk down a section of  mowed trail through a pasture or woods. sparkling back at you will be hundreds of dots of light glowing back at you.  In my yard these will often be sapphire blue providing an unusual contrast with the flashing yellow-white fire flies as Nature provides its own version of fireworks.

Common house mouse apparently provides food for household beetles.

 Mice                                                       Remove                                                              Trap

 Populations of mice can grow to considerable numbers in old houses. I had been hearing mice in the false ceiling of my bedroom and started setting out traps. A dozen mice and two months later, I am still catching them. When I seem to catch them out of an area I move the traps and try there. I recently had Whitehall re-roofed, and I suspect the pounding and traffic displaced mice from the attic to the lower floors.

  As I reduce the population of mice, I find that I also reduce the numbers of small black beetles that I find on my bed and on  other surfaces in the house. Apparently there is a “cycle of life” going on here with the mice commonly feeding on other insects, and maybe the beetles too, and the beetles feeding on the mice’s droppings.

  A partial solution to solving a beetle infestation in your house is to aggressively trap mice and other rodents. This method of population control needs to be continued for a period of months to have a notable impact. My dogs help reduce the rodent population near the house by catching occasional squirrels and wood rats. They enjoy the work, but dig up the yard in the process as they also go after moles and chipmunks. The last two cause me no particular problems in the house; but any small rodent is considered “fair game” for hound dogs.   

 Employing the services of a good mouse-catching cat would also be an option; although at the expense of the local bird populations as collateral damage.

  It appears that very few things  are either all good or all bad. Adverse consequences will oftentimes arise from well-intended acts. The alternatives are to do nothing, or take measured risks with the expectation that the beneficial impact will be better than doing nothing.  All life is a measure of risk taking.

 Wisteria vine                              invasive                                    eradicate

Old home site completely overgrown with several acres of wisteria-choked trees and brush.

   One sure way to locate old home sites in the South is to look for escaped and invasive purple globular clusters of wisteria blossoms hanging from the trees. This vine was brought in as an ornimental plant from China by the mid-1800s and has been planted around homes every since.

Purple death on pine tree.

  The blossoms come on in profusion for a few days in the Spring (early April in my part of GA), and then the vines proceed to take over homes, forest, lawns and anything else that they can climb on. They kill trees by choking them to death as they wind around the trunks and also make them more likely to lose limbs during winter storms because of the added ice and snow that clings to vines.

  Although the purple variety from China already had a very stong start, a white variety from Japan is also grown. This  has also gotten out of control, but the older variety is more common. It is not that we did not already have enough viney things in the Southeast with briers, honeysuckle (another import), kudzu (another import), blackberry vines and a host of others. Oh, I nearly forgot about poison oak and ivy. We have them too.

  Burning, poisoning, chopping and mowing will control its spread, but nothing but relentless hand pulling over a period of years will keep even a small piece of ground clear of the pesky plant.

Plant wisteria as an isolated tree in mid-lawn and be relentless about prunning limbs and roots.

  If you must plant it, plant it as an isolated bush in a clear patch of yard and trim it relentlessly. When you feel that you can no longer tend the plant properly, have it killed. Even so, it will take a couple of seasons follow-up to insure that you were successful.

  We have this plant now, but need no more of it.

Harmless, but smelly               Exclude                         Vacuum

Coming in through any opening these Lady Bug-like bettles overwinter in houses throughout the South.

  With a range that has expanded throughout the Southern States from Georgia to Oklahoma, the Formosan beetle, a Lady Bug look-alike, has been relentlessly invading homes in rural and forested areas.

  These beetles move inside with us, like wasp, and overwinter in clusters. They are most visible in the Fall when they come in and in the Spring when attempt to find their way out. Unlike the domestic Lady Bug, these beetles bite. They are not aggressive, but if handled (or rolled over on in bed) they will take a pinch. The bites are not dangerous, and I have never known one to draw blood; although I suppose that this could happen with individuals who are on blood thinners.

  Control measures are primarily exclusion by calking up holes around windows and doors and by relentlessly vacuuming them up when they come inside. You will never get them all, but you can temporally reduce their numbers.

  If you crush them they will stink and this smell may linger for days. While perhaps satisfying to stomp a few, vacuuming is the best method. 

  These bugs do have helpful biological function in that they feed on plant pests, like aphids. These invasive insects are now part of America’s permanent insect population, wanted or not. As creatures they are somewhat interesting in that each one has a unique arrangement of spots and a slightly different color. Most of us would think better of them if they were not so “friendly” and stayed outdoors.
