This pest is a hitchhiker that clings to materials like luggage, clothing, seats, and other similar spots to get around. As such, they can easily go home with you if you've been traveling.

Bed bugs have a flattened body that's oval-shaped and brown in color. They only grow to about 3/16 of an inch in length when fully grown. After eating, their color becomes red and they swell in size.

Bed bugs aren't a direct threat to people's health since they don't transmit diseases, however, they do leave behind itchy red welts that can get infected if scratched too hard. Some people have also reported mental strain due to the difficulty in controlling an infestation.

Rodents are a class of small mammals that gnaw, burrow, and scamper along the floor and inside the walls. They are a common invader of residences and businesses alike.

Field Mouse

As its name implies, this mouse is usually found in rural areas outdoors. While they rarely invade homes, they are known to get inside at times. Field mice are brown in color and grow to about eight inches long. They are found throughout the U.S.

Norway Rat

The Norway rat is the largest rat, at an average length of about 16 inches. They are brown in color with an off-white colored underbelly. This species has a long tail, protruding black eyes, a blunt nose, small ears, and a dense body.

Roof Rat

Smaller than the Norway rat at about 12 to 14 inches long, this species is an excellent climber and is usually black in color. They possess a scaly, hairless tail and are fans of fruit and vegetables.

Rodents are a threat to your health thanks to the number of pathogens they carry. Illnesses such as hantavirus, salmonellosis, and bubonic plague are just a few of the possibilities. They also carry ticks and fleas, which transmit their own diseases.

All of the rodents mentioned love to gnaw on things and they possess sharp claws. Therefore, property damage in the form of frayed or chewed-through wires and scratches on the floor or walls are common.

In addition to our rodent control solutions, implement the following tips to remain protected:

  • Seal up entry points including holes, cracks, and crevices.
  • Maintain proper landscaping and trim back overgrown vegetation near your building.
  • Keep your home free of clutter and debris.
  • Vacuum and sweep the floors regularly.
  • Store food properly.


formosean termites

There are two common species of termites that frequent our Houston homes and businesses:

Subterranean Termite

Arguably the most destructive termite species, the subterranean termite is made up of three different classes.

  • Reproductives: Within this class, you'll find the queen, king, and alates. The queen is the ruler of the colony and the largest termite while the king notably smaller. Alates are the termites responsible for reproducing and starting new colonies, and grow up to 1/2" in length.
  • Workers: Worker termites are cream colored and only grow to 1/4" in length. With their small jaws, they chew away at wood and move various materials for the colony.
  • Soldiers: This termite class is similar to the worker class, but they have different features like a wide, flat body, large mandible, and a rectangular head.

Formosan Termite

This species is another type of subterranean termite, often considered to be "super termites" thanks to their voracious and aggressive behavior.

Formosan reproductive alates grow to about 1/3 an inch in length and are pale to brownish-yellow in color. The soldier termites have heads that are rounded on the side with the head tapering towards the front.

Both species of termite are a significant threat to your property due to the high levels of cosmetic and structural damage they cause. Due to their ability to go undetected for a long time and high reproductive rate, the damage can grow out of control before you know there's a problem.

The following prevention tips, in conjunction with our effective termite control services, can help keep termites away from your property:

  • Inspect the property for signs like mud tubes, frass (excrement), and hollow-sounding wood.
  • Keep water from pooling near the foundation of the building.
  • Seal all entry points including cracks, crevices, and holes in the foundation.
  • Prevent soil-to-wood contact at the building's foundation.
