Kuidzu Bugs on the Move

Kudzu bugs

As the weather has begun to cool, I have started getting calls about large numbers of insects trying to get into people’s homes.  Most people are familiar with the Asian Lady Beetles, but they do not recognize this insect.  This insect is the kudzu bug.  The cooler temperature has caused them to move from the kudzu patches and start looking for a place to spend the winter.  And your nice warm home is a good spot.

The kudzu bug was first reported in Mississippi in 2012 and is rapidly spreading throughout the state.  The most recent report has this insect in 33 counties.  It was necessary to spray some soybean fields in some areas to prevent economic damage from them.

This time of year they are just an annoyance.  To keep them out of your home, seal all window/door cracks. Screens will also help prevent kudzu bug entry. It is important to make sure soffit vents and peak vents on homes have good screening in addition to window and door screening.

       Sweep the kudzu bugs that do get into your home into a dustpan and put them in a bucket of water.  If you vacuum them up, they will release their stink into the vacuum canister and that can stay in it for several weeks so change canister bags as soon as you get through.  It is not a good idea to pick them up in your bare hands either.  It takes multiple applications of soap and water to remove the odor.

To further reduce entry into your home, you can apply insecticides around doors and windows.  You can use any labeled outdoor insecticide to kill them.   If you kill large amounts to them, you need to sweep and remove since they will produce a foul odor as they decompose.  Their carcasses can also attract ants.

BIG, Scary, Yellow Spiders!

          Does your yard look like it is already decorated for Halloween because of all the spider webs covered with huge spiders?  In the fall we see an increase in these large webs.

One of the more colorful ones is the Golden Silk Spider (Golden Silk Orb Weaver), Nephila clavipes: This is a large orb weaver (web builder) with webs that are several feet wide. They are often called ‘banana spiders’ by people in south Mississippi know them by this name. Mature females range from 1 to 1 ½ inches long and have a leg span of 3 to 4 inches. The abdomen is orange or yellow with white markings and is elongate and tube-shaped; the front part of their body is silver. The legs are yellow, banded with black, and have distinctive tufts of black hairs concentrated at the joints

           

Golden silk spiders suspend their webs between trees and shrubs in open woods and wooded landscapes. They can be quite numerous in the southern part of the state, and it is not uncommon to see several spiders nesting near one another, presumably sisters that developed from the same egg mass. I have several webs suspended between trees and shrubs lining my driveway.

 

Like regular garden spiders, they can inflict a painful bite if mishandled, but they are not aggressive and the bite is usually not serious. Because their webs can be so numerous, these spiders can be a nuisance to hikers, bikers, and people who work in the yard or play outside. It is shocking to feel one of these large spiders crawling up the back of your neck after you have unknowingly walked through its web.

 

This spider produces one of the strongest silks, and hence one of the strongest fibers, known to man. It gets its name from the golden color that the silk has in certain lighting. Golden silk spiders occur throughout the Southeast and in Central and South America. They are quite common in the southern third of the state, but it is unusual to encounter them much north of I-20.  I live in Meridian just a few miles north of I-20 with several large webs in my yard.

           Leave them alone and these spiders will not bother you.  They will silently and colorfully catch insects for you.  Not to mention they will provide free Halloween decorations.
