Jorō SpiderTrichonephila clavata
Jorō Spider Characteristics:The Jorō spider can be commonly confused with the banana spider & the garden spider, the Jorō spider shares the same similarities with their black and yellow markings. The biggest difference between the two spiders is their web placement. Banana spiders and garden spiders will build the webs closer to the ground. However, the Jorō spider will build their web higher off the ground, you can find their webs above your head.
Are The Jorō Spiders A Problem?Since Jorō spiders can multiply in great quantities, they have become more of a nuisance for most homeowners. Our native species of orb weaver spiders can produce approximately 200-500 eggs compared to the 400-1500 eggs the Jorō spiders produce. When it comes to nature's pest control, spiders are very beneficial insects; the Jorō spider is no exception. When it comes to feeding on various insects, orb-weaver spiders diet is broad when it comes to feeding on insects, like biting flies, beetles, and even the invasive brown marmorated stink bug which was first discovered in America in 1998. Entomologists and bug experts have all come to the same conclusion, an article written by Beth Gavrilles says it the best "Like It or Not, Jorō Spiders are Here to Stay". She quoted the director of the Georgia Museum of Natural History Byron Freeman, “My guess is that this will be no different than the banana spider, and I don’t know that we can assess what the effect of the banana spider has been at this point,”. So in conclusion it sounds like the Jorō spider has made Jefferson County its new home, certainly this uninvited pest is now a long term guest in Jackson, GA. References

A Quick Bio On Argentine Ants
Characteristics of the Argentine Ants
Worker ants are light brown and about three-sixteenths of an inch long. A mature colony of Argentine ants can consist of a million or more worker ants and hundreds of queens. Argentine ants form large colonies that consist of numerous nest sites that encompass large foraging areas (often sharing your ant problem with your neighbors). Ants may travel hundreds of feet from nest sites to feeding sites and other nest sites on well organized for aging trails. Argentine ant trails have been measured in excess of 350 feet in Georgia.
