 Southern Black Widow

A black spider has a red hourglass on the underside or top of the abdomen. Some have a pair of red spots or no markings at all. The female is generally twice the size of males and has large venom glands. Its bite is harmful to humans sometimes fatal if proper medical treatment is not provided. Many injuries to humans occur as defensive bites when a spider is squeezed pinched or a finger is accidently thrust into its web.

 Brown Recluse Spider

 A brown recluse is generally about ¾ inches in length and are light to medium brown. They have markings on top of their abdomen that resembles a violin. This spider builds webs in sheds, closets, garages. Indoors, they favor cardboard boxes. Although the bite can be harmful, it is not common. However, children, elderly and ill persons, may be more susceptible to a bite. A bite can cause a skin ulcer that will destroy soft tissue, taking months to heal and leaving scars. It is generally advisable to seek medical attention for a diagnosis and treatment.

 Southern House Spider  The males resemble the brown recluse is color and body shape but are solid brown and more slender. The females are dark brown or black and more compact but neither grows to more than 2 inches. The abdomen is covered with fine velvety light gray hair. The females are rarely seen since they are building webs around crevices. The males wander in search of insects and other females to mate with. These spiders are not aggressive, do not bite unless threatened and their mouthparts are generally too small to penetrate human skin.

They have many legs, are cylindrical and about ¾ to 11 inches in length dark (between 36 and 400) brown or black in color. Some millipedes can roll into a ball. Their diet generally consists of decaying leaves and other plant matter. They will eat emergent seedlings. In the spring and again in the fall, they will move into unexpected places such as your home in search of a mate and to relocate. After a couple of weeks, they generally leave on their own. They are not harmful to humans.

 Southern Chinch Bug  are insects about 3/16 inch long with black bodies and fully developed set of wings and are a major nuisance to St. Augustine grass. Even though the chinch bug has the ability to fly, it generally walks from a heavily attacked area to a fresh lawn. Research has shown that they can cover over 400 feet in an hour. The nymphs and adults use their sucking mouthparts to suck the sap from the grass until it changes from a healthy green color to yellowish-brown and dies. Homeowners know they have a chinch bug infestation when they notice expanding brown areas in their lawns.

 White grub

 The most prevalent type in south Florida is the Japanese beetle. The grub is the larval stage (the feeding stage) the adult is copper and green and about 6/10 inches long. In the larval stage the creamy colored grub lives in soil and feeds on the lawn roots. This will weaken the affected areas, turning the grass brown and killing it. Japanese is considered pest to about 200 species of plants.

Aphid  are small sap sucking destructive pests (about .04 to .39 inches) that feed upon cultivated plants. Their body color can range from green, black, brown, pink or clear. As they feed upon a plant, aphids can transmit plant viruses to the plant. These viruses are powerful enough to occasionally kill the sieged plant. Plants that are under attack by aphids may demonstrate such symptoms as yellowing, curled leaves, browning and wilting.

are unarmored scale insects that fed on plants and citrus. They link onto plants and secrete a waxy layer which serves as protection while they ingest the plant juices. Small infestations may not cause any serious damage but in greater numbers, they can force leaf drop.

Florida wax scale  Scale are tiny sucking insects that damage plants by sucking the liquid from plant tissue. If left unchecked, the leaves will yellow and the plant will ultimately die. Scale insects are small oval shaped raised dots on the underside of plant leaves. They are difficult to notice unless you are looking for them. The scale releases a honeydew secretion onto the plant. This honeydew causes a reaction that turns into sooty mold, a black fungus. Discolored leaves and stems are indicative of scale.

White fly

 More than 1550 species have been named. The three most important afflicting south Florida are the fig, spiral and nesting. The fig white fly was introduced several years ago and has concentrated the ficus hedges and trees causing great damage to them and eventually death. The minute white colored fly feeds by piercing the living tissue of plants and releasing a toxic saliva to affect the plant’s overall health. Whiteflies gather in massive numbers and will quickly overwhelm a plant. The Rugose Spiraling whitefly attacks gumbo limbo trees and certain varieties of palms including coconut palms. The nesting whitefly is a relatively new whitefly and is also attacking ficus.

drywood termites 200x155Source: University of Florida Sub Termites These termites originate from the ground and make their way into a house generally at ground level through cracks, in the house slab, kitchen or bathroom pipes or a water source near the house or a roof leak. If left untreated, subterranean termites can cause severe damage by feeding on the wood in a house.

Unlike the subterranean termites, the drywood termites do not need any soil contact or a water source. This termite generally enters a structure at a high level such as the roof, roof line, fascia or soffit. It will establish itself in the attic, a window frame, door frame or a wall and work its way downward. This termite may be in a house for several years before damage or termite droppings (frass) is evident.
