Common Household Pests In Texas

Your home is a target for many Texas bugs, especially during the hot summer months. These pests are looking for food, water, and shelter, and your house provides all three. Here are the ones you are most likely to find inside.

Fire Ants

Fire ants are everywhere in Texas. They build large mounds in lawns and fields, and they are aggressive when disturbed. Their sting is painful and causes a burning sensation, followed by a white pustule that can itch for days.

Appearance: Reddish-brown, about 1/8 to 1/4 inch long.
Behavior: Build mounds that can be up to 18 inches tall. They swarm quickly if the mound is disturbed.
Risk: Stings can cause severe allergic reactions in some people. They can also damage electrical equipment by chewing through wiring.
Control: Use bait treatments in the spring and fall. Pouring boiling water on mounds can kill the colony, but it may also kill grass.

German Cockroaches

These are the most common cockroach in Texas homes. They are small, fast, and breed rapidly. If you see one during the day, you likely have a large infestation.

Appearance: Light brown to tan, with two dark stripes on the back of the head. About 1/2 to 5/8 inch long.
Behavior: Prefer warm, humid areas like kitchens and bathrooms. They are nocturnal and hide in cracks and crevices.
Risk: They carry bacteria and can trigger asthma and allergies, especially in children.
Control: Keep your home clean, seal cracks, and use gel baits or boric acid. Professional treatment is often needed for severe infestations.

Subterranean Termites

Termites cause billions of dollars in damage each year in Texas. They live in underground colonies and build mud tubes to reach wood above ground. They are silent destroyers, and you might not know you have them until the damage is done.

Appearance: Worker termites are pale and soft-bodied. Swarmers are dark brown or black with two pairs of equal-sized wings.
Behavior: They eat wood from the inside out. They build mud tubes on foundations, walls, and pipes.
Risk: Structural damage to your home. Repair costs can be thousands of dollars.
Control: Regular inspections by a pest control professional are essential. Liquid soil treatments and bait stations are the most common control methods.

Kissing Bugs

Also known as conenose bugs, these insects are a serious health concern in Texas. They are named because they often bite people on the face, especially around the mouth. They can transmit a parasite that causes Chagas disease.

Appearance: Dark brown or black, with orange or red stripes on the edges of the abdomen. They have a cone-shaped head and are about 3/4 to 1 inch long.
Behavior: Nocturnal and attracted to lights. They feed on the blood of mammals, including humans and pets.
Risk: The bite can cause severe allergic reactions. Chagas disease can lead to heart problems years later.
Control: Seal cracks and gaps in your home. Remove piles of wood, rocks, and debris from around the house. Use screens on windows and doors.

Types Of Bugs In Texas

Now let us look at a broader category of bugs you will encounter outdoors. These insects are part of the natural landscape, but some can be dangerous or just plain annoying.

Tarantula Hawk Wasps

This is one of the most intimidating insects in Texas. It is a large, blue-black wasp with bright orange wings. The female hunts tarantulas, stings them, and drags them to a burrow where she lays an egg on the paralyzed spider.

Appearance: Body is blue-black, wings are orange or rusty red. It can be up to 2 inches long.
Behavior: Females actively hunt tarantulas. Males are often seen feeding on nectar from flowers.
Risk: The sting is considered one of the most painful of any insect. However, they are not aggressive and will only sting if provoked.
Control: Avoid handling them. If they are near your home, remove tarantulas and their burrows.

Velvet Ants

Despite the name, velvet ants are actually wasps. The females are wingless and covered in dense, brightly colored hair. They are often called “cow killers” because of the intense pain of their sting.

Appearance: Females are wingless and fuzzy, usually red, orange, or yellow with black bands. They are about 3/4 inch long.
Behavior: They are solitary and often seen running on the ground. They are actually wasps that parasitize ground-nesting bees.
Risk: The sting is extremely painful, but they are not aggressive. They will sting if stepped on or handled.
Control: Wear shoes outdoors. Avoid walking barefoot in grassy areas.

Red Imported Fire Ants

We mentioned fire ants earlier, but they deserve a second look because of their impact. They are an invasive species that has spread across Texas, outcompeting native ants and causing ecological and economic damage.

Appearance: Reddish-brown, with a darker abdomen. Workers are about 1/8 inch long.
Behavior: They build large mounds in open areas. They are aggressive and will swarm any threat.
Risk: Stings cause painful welts. They can damage crops, electrical equipment, and even kill young livestock.
Control: Broadcast baits are the most effective method. Treat your entire yard, not just individual mounds.

Blister Beetles

These beetles are common in gardens and fields. They are named for the blistering agent, cantharidin, that they release when crushed. This chemical can cause painful blisters on human skin.

Appearance: Elongated, soft-bodied beetles. Colors vary from black to gray to striped. They are about 1/2 to 1 inch long.
Behavior: They feed on plants, especially alfalfa, tomatoes, and potatoes. They are often found in groups.
Risk: Do not squash them. The chemical can cause blisters. If livestock eat hay containing blister beetles, it can be fatal.
Control: Remove them by hand while wearing gloves. Use insecticidal soap or neem oil on plants.

Stinging And Biting Insects

Some Texas bugs are known for their painful stings or bites. Knowing how to identify them can help you avoid getting hurt.

Paper Wasps

Paper wasps are common around homes and buildings. They build open, umbrella-shaped nests under eaves, in attics, and on tree branches. They are not as aggressive as yellow jackets, but they will defend their nest.

Appearance: Slender body with a narrow waist. Colors are usually brown with yellow or red markings. They are about 3/4 to 1 inch long.
Behavior: They build nests from chewed wood fibers. They are beneficial because they eat caterpillars and other pests.
Risk: Stings are painful and can cause allergic reactions. Multiple stings can be dangerous.
Control: Remove nests at night when wasps are less active. Use a wasp spray or call a professional.

Yellow Jackets

Yellow jackets are more aggressive than paper wasps. They build their nests underground or in wall voids. They are attracted to food and sugary drinks, making them a nuisance at picnics and outdoor events.

Appearance: Bright yellow and black bands. They are about 1/2 to 3/4 inch long.
Behavior: They are social and live in large colonies. They are scavengers and will eat meat, sweets, and garbage.
Risk: They sting repeatedly and can chase you. Their stings are painful and can cause severe allergic reactions.
Control: Locate the nest entrance. Use insecticidal dust or aerosol sprays. Professional treatment is often needed for underground nests.

Africanized Honey Bees

Also known as “killer bees,” these are hybrids of European honey bees and African honey bees. They are more defensive than regular honey bees and will chase you for a quarter mile if their hive is disturbed.

Appearance: They look almost identical to regular honey bees. Slightly smaller, but you cannot tell them apart without a microscope.
Behavior: They build hives in unusual places like water meters, old tires, and sheds. They respond quickly and in large numbers to threats.
Risk: They can deliver hundreds of stings in minutes. Their venom is no stronger than regular honey bees, but the number of stings makes them dangerous.
Control: If you find a hive, do not approach it. Call a professional beekeeper or pest control service immediately.

Other Notable Texas Bugs

There are many other insects in Texas that are worth knowing about. Some are just interesting, while others can be a problem.

Texas Redheaded Centipede
