What You Need to Know About Termites in Arizona

Residents of Arizona need to watch out for termites. They are tiny bugs from the Isoptera order. Termites eat wood, dead plants, and other organic stuff. If ignored, they can cause severe damage to homes.

This guide contains info about how to keep homes safe from these pests. By knowing the life cycles, behavior, habitats, and species in Arizona, homeowners can protect their homes. No house is 100% safe, but taking steps to reduce risk is necessary. This will help keep properties safe from these critters.


Types of Termites in Arizona

Termites? In Arizona? Yes! They are a vital part of the state’s wildlife. Different kinds of termites exist here, each with its own traits. Some are only located in certain places, while others can be seen all over.


Let’s explore the different types of termites that can be found in Arizona:

Subterranean Termites

Subterranean Termites are the most common kind of termite in Arizona. They live underground and build large colonies. These colonies can cause major damage to buildings and wood structures. The termites build mud tubes to move between their colony and food sources. They eat dead plants, wood, paper, and insulation, damaging furniture, walls, floors, and even foundations.

Subterranean Termites are identified by swarming reproductive individuals with wings or wing buds. If these swarmers appear indoors, it usually means there’s an active infestation. Even if no swarmers are seen, fumigation should still be considered, as the termites may live underground below exterior surfaces like driveways, walkways, and patios.

Treatment options include:

  • Bait systems, with specialized monitoring stations around the perimeter of the structure.
  • Liquid treatments, where a termiticide is injected into locations where the termites build mud-tubes.

Treatments depend on the location, with the goal of complete elimination of activity and prevention of future infestations.

Drywood Termites

Drywood termites are found all over Arizona and are most common in the southwest. They feed on wood and prefer dry, sound wood with low moisture. They swarm from late summer to early fall.

To prevent infestation, replace damaged wood fixtures quickly. This includes window frames, siding, and beams. Install screens over vents and caulk cracks. If you spot signs of termites, contact a licensed pest control expert right away.

Remember, drywood termites are hard to detect. To protect your property, inspect attic areas regularly for signs of infestation, like frass or wings. Windowsills and windows screens/frames can also indicate swarming activity.

Formosan Termites

Formosan termites, otherwise known as Coptotermes formosanus, are an aggressive and invasive species. Native to the tropics and subtropics of Asia, they thrive in warm, humid climates, making Arizona especially prone to infestations. These termites cause more destruction than other species in less time.

Formosan termite colonies can contain up to several hundred thousand members. They create tunnels that can span hundreds of feet in length. With such huge numbers, they can quickly invade homes and wooden structures from a long distance away. Homeowners may not even realize they have an infestation until it’s too late.

Formosans prefer warmer temperatures, so they’re active in Arizona all year round. Fortunately, eco-friendly methods are effective for their control and removal. It’s important to check for infestations before buying a home or doing any woodwork. This will help prevent destructive Formosan termite colonies from taking up residence.

Signs of Infestation

Termites are a pesky issue in Arizona. Homeowners must be aware of the risk of infestation. Early detection of signs can help to stop it getting worse.

Look out for:

  • Mud tubes near the house’s base.
  • Piles of termite wings.
  • Wood that is hollowed or damaged.

Recognizing the signs is key to protecting your home.

Mud tubes

Mud tubes, or shelter tubes, are a sure sign of a termite infestation in Arizona. These tubes are made with mud and saliva. They help termites burrow from the ground into your home or other wood structures. They tend to be 1-2 inches in diameter. They look like small tunnels along walls, floors, or woodwork.

If you see mud-like structures on your house’s foundation or on your walls, inside or out, it’s likely an infestation. Contact a pest professional asap.

Discarded wings

In Arizona, discarded wings are a tell-tale sign of a termite infestation. These flying termites, known as swarmers, come out in warm weather to find colonies. They shed their wings when they have found a suitable spot. These wings can be spotted near windowsills, door frames, baseboards, and edges of rooms. Another sign is multiple wings by windowsills, which come from many swarms over time.

Homeowners should check regularly for wings. If found, contact a pest control specialist.

Visible damage to wood

Visible damage to wood is one of the most obvious signs of termite infestation. This could be large hollowed-out sections in beams or support poles. Or small pinhole-sized holes in wooden walls and surfaces. If you spot any wood damage, call a qualified pest professional. It could signal a much bigger problem.

It’s important to tell the difference between termite damage and powder post beetles. An exterminator can help you create a plan to treat the issue and stop further damage.


Stop termites from invading your Arizona home! Be aware of the risks and take measures to keep them away. Build a foundation to repel pests, inspect your home regularly and maintain it properly. These are all important steps to stop a termite infestation.

In this section, we will delve into these preventive tips:

Regular inspections

Termite inspections should be done every four to six months for prevention of infestations. This is important for detecting if a previous treatment worked. An expert inspector can spot potential problem areas that may attract termites. They can also identify signs of current activity and determine the species present.

The inspection should include interior and exterior locations such as:

  • foundation walls
  • attic areas
  • window sills
  • moist surfaces like tubs, sinks, and faucets

If evidence of subterranean access points or unexplained structural damage is found, more investigation by a technician is needed.

Regular inspections and preventive measures are key for protecting a home from costly termite damage in Arizona.

Treating wood

Different methods can be used to prevent wood from termites, such as preservatives and chemicals. The most common way is to treat the wood with a chemical preservative or pesticide.

The chemicals used depend on the species of termite, the environment, climate, and type of wood.

  • The chemical is either sprayed or saturated with liquid formulae.
  • It’s important to apply correctly for it to be effective. For example, only treating the outside siding doesn’t protect against infestations inside walls or crawl spaces.
  • Planning should be done prior to treatments.
  • Wood compromised by an infestation may need more intensive treatments like fumigation or bait systems to remove the termites from their hiding spots in beams and joists.

Using baits

Baiting is a great way to get rid of termites. Traps contain slow-acting toxicants which the termites eat and share. The idea is to target colonies and monitor them. These systems are placed in the ground near a structure. Inspect and maintain them every three to six months, based on factors like weather and type of bait. Contact a licensed pest control professional for advice before using this treatment.

Baiting systems come in two forms:

  • Large devices with multiple bait rods or cartridges are placed in-ground.
  • Smaller devices with bait material for ants are placed above the ground.

Success depends on identification, service and inspections. This helps prevent re-infestation.


Termite infestations? Serious business! Identify and remove the affected areas quick as a bunny. Taking further preventative steps is also important, like treatment and prevention.

Treating termites in Arizona requires special techniques and products. Let’s talk treatments. What type of treatment to choose? How to apply it effectively? All this and more in this section.

Chemical Treatments

Chemical treatments are an effective way to eradicate and protect against Arizona’s termites. Moisture barriers, bait systems, and liquid termiticides are the methods used. These create an invisible block to stop termites entering through the soil and last up to two years.

  • Bait systems lure pests away from the structure.
  • Termiticide dispenses into the stations and lasts up to ten years.
  • Liquid termiticides can be sprayed onto existing structures. A thorough application is necessary for complete coverage and protection. These chemical agents last up to five years without renovation.

Heat Treatments

Heat treatments are a great termite management option for Arizona homes. They can get rid of infestations quickly, completely, and safely. It only takes a few hours. Plus, no furniture has to be moved or cleared out.

An exterior containment tent is set up around the area and the temperature is raised to 140-150°F. This lasts two to two-and-a-half hours. The heat penetrates all the wood in the area and there’s no escape for the termites. Heat treatments also prevent eggs from hatching and get rid of the colony infestation sources.


Fumigation is a termite treatment used by pro pest controllers. They cover the structure with a tent and release a fumigant in the air. This kills the termites. Everyone, pets, and plants must stay out of the home for 72 hours. This gives the fumigant time to go away.

Fumigation can be costly, yet it can work for serious infestations.



Termites are a problem in Arizona and can cause costly damage to homes and commercial buildings. Homeowners should be aware of signs of an infestation, such as swarms, flight tubes, and fungi. To protect their property, they should get regular inspections from a professional pest control company.

Also, they should treat their property with approved chemicals and use preventative barriers around building foundations. Knowing how to prepare for termite problems is the best defense against costly damages.
