Ants 

White-footed Ants
Although not native to North America, the insects were accidentally imported into Florida where they were first collected and identified in 1986. The white footed ant neither bites nor causes structural damage, yet it is considered a nuisance due to their explosive population growth. New information from Bolton indicates that the white-footed ant in Florida is Technomyrmex difficilis.

American Cockroaches
American cockroach adults grow to an average length of around 4 centimeters (1.6 in). They are reddish brown and have a yellowish margin on the body region behind the head. Immature cockroaches resemble adults except that they are wingless. American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures around 29 C (84 F) and do not tolerate cold temperatures. In residential areas, these cockroaches live in basements and sewers, and may move outdoors into yards during warm weather.

Brown-banded Cockroaches
Brown Banded Cockroaches is a large species of cockroach, winged, and growing to a length of 1 1/4″-1 1/2″. It is dark, reddish brown in color. The insect is very similar in appearance to the American cockroach, and may often be mistaken for it. The insect can travel quickly, often darting out of sight when someone enters a room, and can fit into small cracks and under doors despite its fairly large size. It is known to be very mobile; it also has wings which allow it to be quite a capable flier.

Black Widow
Black Widow Spiders are about .5 inches long, 1.5 inches when the legs are spread. They have a shiny, globular abdomen and are black and sometimes brown. Females usually have a reddish hourglass shape on the underside of her abdomen. Some species have a series of red spots and two crosswise bars on the underbelly. Males about half the female’s size, with smaller bodies, and longer legs Males usually have yellow and red bands and spots over the back as do the immature stages. Newly hatched spiderlings are predominately white or yellowish-white, gradually acquiring more black and varying amounts of red and white with each molt. Juveniles of both sexes resemble the male and are harmless to humans.

Pantry Pests

Cigarette Beetle
The cigarette beetle is one of the most common household insect pests. It can be found throughout the year, but seems to be more common in the fall and winter months. The adult beetles are oval, about 1/10 inch long, and are covered with small hairs which give them a silky, yellowish-brown color. Adults are strong fliers and prefer subdued light and temperatures over 65 degrees Fahrenheit.

Weevils
A weevil is any beetle from the Curculionidae superfamily. They are usually small, less than 6 mm (1/4 inch), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). The rice weevil and granary weevil are pests of stored grain and seeds. They develop inside whole grain kernels as small, white, wrinkled, grub-like larvae. There is generally no external evidence that the larvae have been eating and growing inside the seed until after about one month when the adult weevil chews through the seed coat and emerges. The adult weevils are 1/8th inch long and have slender, hard-shelled bodies that appear pitted or scarred with tiny holes. They are brown to reddish brown in color. The rice weevil has four faint yellowish spots on the back of the abdomen. The granary weevil is uniformly colored with no spots.

Indian Meal Moth
Indian Meal Moth is a moth of the family Pyralidae. Its larva is a common grain-feeding pest found around the world, feeding on cereals and dry grain products. These larvae often leave their food supply when they are ready to spin their cocoons and they may wander about in search of a suitable place to pupate. They are frequently found in unsuspected places because of this wandering behavior.

other household pests

Millipedes
Millipedes are slow-crawling, round-bodied pests which have two sets of legs on each body segment. Millipedes develop best in damp and dark locations with abundant organic matter (food). They often curl up into a tight “C” shape, like a watch spring, and remain motionless when touched. The body is long and cylindrical. Millipedes can be found in piles of grass clippings, a wooded lot close to the house, excessive mulch around the house, and similar locations.

blood feeding pests

Fleas
Flea is the common name for any of the small wingless insects of the order Siphonaptera. Fleas are external parasites, living off the blood of mammals and birds. Fleas are small (1/16 to 1/8-inch (1.5 to 3.3 mm) long), agile, usually dark colored (for example, the reddish-brown of the cat flea), wingless insects with tube-like mouth-parts adapted to feeding on the blood of their hosts. Their bodies are laterally compressed, permitting easy movement through the hairs or feathers on the host’s body (or in the case of humans, under clothes).

Ticks
Ticks are blood-feeding parasites that are often found in tall grass and shrubs where they will wait to attach to a passing host. Physical contact is the only method of transportation for ticks. Ticks do not jump or fly, although they may drop from their perch and fall onto a host. Some species actively stalk the host by foot. Young ticks have six legs, and mature ticks have eight legs. They are about the size of a sesame seed, and males are black; females have a brick-red abdomen with a black shield-like plate close to their head.

Lawn Pests

Chinch Bugs
Chinch Blissus leucopterus also known as the true Chinch Bug is a small (about 1/8th inch (3-4 mm)) North American insect in the order Hemiptera and family Lygaeidae.Adult Chinch Bugs are black with opaque wings; wing length varies from as long as body to only one-third length of body, and each wing bears a distinctive, triangular, black mark. Nymph are wingless and smaller than adult but similar shape; head and thorax brown; eyes dark red; abdomen pale yellow or light red with black tip. They feed on forage, lawn, and wild grasses plus crop plants, including wheat, corn, sorghum, oats. Chinch bugs pierce the plant with their mouth parts and suck out the plant sap. This feeding prevents normal growth and results in dwarfing, lodging, and yield reduction. Severe infestations during early development may cause plants to wilt and die prematurely.

White Grubs
White Grubs are the larvae of Scarab beetles. More than a dozen different species may damage turf in the Southeast. All are C-shaped, white to dirty white in color, with brownish head and legs and usually with a darker grey area at the tip of the abdomen. The adults are medium-sized beetles that feed on a variety of trees and shrubs. Some of them, such as   Japanese beetles and Green June beetles, are serious pests of ornamentals and certain fruits including figs, peaches and grapes.

Mole Crickets
The mole crickets compose family Gryllotalpidae, of thick-bodied insects about 3-5 cm (1-2 inches) long, with large beady eyes and shovel-like forelimbs highly developed for burrowing and swimming. They can also fly—the adult mole cricket may fly as far as 8 kilometers (5.0 mi) during mating season, is active most of the year, and spends the winter in hibernation. Younger insects can have shorter wings, and their appearance varies by species, with some resembling grasshoppers or very large ants or dark-colored “termites” when wings are short.

ornamental pests

Black Sooty Mold
Black Sooty Mold is a sooty, gray-black and velvety, often crust-like coating may develop on the leaves, needles, fruits and branches of certain plants. The coating is actually the growth of one of several species of black-colored fungi or molds. Sooty molds often grow on sidewalks or fences under infested trees and are considered to be a cosmetic or aesthetic problem.

Leaf Miners
Leaf miner is a term used to describe the larvae of many different species of insect which live in and eat the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera) and flies (Diptera), though some beetles and wasps also exhibit this behavior. Like Wood boring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves themselves, selectively eating only the layers that have the least amount of cellulose. In attacking Quercus robur they also selectively feed on tissues containing low tannin levels, which the tree has produced in greater abundance as a defense.

Whiteflies
Whiteflies are small, winged insects that typically feed on the underside of leaves with their “needle-like” mouthparts. Whiteflies can seriously injure plants by sucking juices from them causing wilting, yellowing, stunting, leaf drop, or even death.

Thrips
Thrips are tiny, slender insects with fringed wings. Other common names for thrips include thunderflies, thunderbugs, storm flies, and corn lice. Thrips species feed on a large variety of sources both plant and animal by puncturing them and sucking up the contents. A large number of thrips species are considered pests, because they feed on plants with commercial value.
Caterpillars
Caterpillars are the larval form of a member of the order Lepidoptera (the insect order comprising butterflies and moths). They are mostly phytophagous in food habit, with some species being entomophagous. Caterpillars are voracious feeders and many of them are considered pests in agriculture. Many moth species are better known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce.

Aphids
Aphids, also known as plant lice are small plant-eating insects, and members of the superfamily Aphidoidea. Aphids are among the most destructive insect pests on cultivated plants in temperate regions. The damage they do to plants has made them enemies of farmers and gardeners the world over, but from a purely zoological standpoint they are a fascinating and very successful group of animals.

Leafhoppers
Leafhopper is a common name applied to any species from the family Cicadellidae. Leafhoppers, also known as hoppers, are minute plant-feeding insects. Leafhoppers have piercing sucking mouthparts, they feed on plant sap and can transmit plant-infecting viruses and bacteria. Species that are significant agricultural pests include the potato leafhopper, beet leafhopper, white apple leafhopper, two-spotted leafhopper, and glassy-winged sharpshooter. A Leafhoppers’ diet commonly consists of plant sap from a wide and diverse range of plants. Leafhoppers mainly consume   vegetation but have been known to indulge in small insects such as Aphids.

Snails and Slugs
Snails and slugs are among the most bothersome pests in many garden and landscape situations. Snails and slugs move by gliding along on a muscular “foot.” This muscle constantly secretes mucus, which later dries to form the silvery “slime trail” that signals the presence of either pest. Snails and slugs feed on a variety of living plants as well as on decaying plant matter. On plants they chew irregular holes with smooth edges in leaves and flowers and can clip succulent plant parts. They can also chew fruit and young plant bark. Because they prefer succulent foliage or flowers, they are primarily pests of seedlings and herbaceous plants, but they are also serious pests of ripening fruits, such as strawberries, artichokes, and tomatoes, that are close to the ground.

Palm diseases & problems

Lethal Yellowing
Lethal Yellowing is a phytoplasma disease that attacks many species of palms, including some commercially important species such as the Coconut and Date Palm. Infected plants will normally die in 3 to 6 months. The only effective cure is prevention, i.e. planting resistant varieties of coconut palm. The first symptom is premature dropping of most or all coconuts, regardless of size. This is termed “shelling” and most of the fallen nuts will have a brown or black water-soaked area immediately under the calyx. The second stage, usually definitive for Lethal Yellowing, is the blackening of new flower stalks. Most male flowers will be dead on the blackened inflorescences and no fruits will set.

Red Palm Mites
The Red Palm Mite, is a pest of coconut, areca palm, and date palms. The red palm mite is bright red with long spatulate body setae and a droplet of liquid at the tip of most body setae in living specimens. All life stages, including the eggs, are red, and adult females often exhibit black patches across their backs. The red palm mite can be distinguished from most spider mites (Tetranychidae) by the red color (including legs), long spatulate setae, flattened bodies, droplets on dorsal body setae and absence of the webbing associated with many spider mites.

leaf spots

Leaf Spots
Most leaf spot diseases develop as small, scattered, circular to oval dead areas in the leaves; usually tan, dark brown, yellow, gray, purple, or black. Some spots are raised, shiny, and coal black, others may drop out leaving ragged holes; some are marked with light and dark concentric zones. Numerous spots develop yellow, purple, red, or reddish brown to black margins; and later, in damp weather, increase in size and number and merge into large, angular to irregular dead areas. Heavily infected leaves may turn yellow to brown, wither, and drop early, weakening the tree. Occasionally, some leaf spotting fungi deform or kill flowers, buds, fruits, twigs, or even small branches.
