Termite identification
Discover what termites look like and the signs to look for.
Termites are one of the most destructive pests, causing an estimated $6.8 billion in property damage each year across the United States.* For businesses and commercial property owners, termite activity poses more than a structural concern. Left unaddressed, infestations can lead to business disruption, loss of inventory, and potential liability issues.
Commercial termite prevention is a strategic investment in asset protection. Proactive measures can help protect commercial buildings, reduce the risk of costly downtime, and preserve the integrity of infrastructure. With professionally managed termite prevention, protection can be seamlessly integrated into ongoing operations, minimizing disruption while providing continuous defense against termites.

Where you might see them
In many cases, signs of termite activity appear before termites themselves are ever seen. Because these pests often hide in walls, flooring, or structural components, early detection is essential in commercial buildings.
- One of the earliest warning signs is the presence of shed wings, often found near windows, doors, or light fixtures after swarming events.
- Because termites feed on cellulose, any wood or wood-containing structure within a commercial property may be at risk. This includes structural framing, support beams, door frames, flooring, pallets, and even paper-based materials stored on site.
- Subterranean termites may leave visible mud tubes along foundation walls, utility penetrations, or crawl spaces as they travel between the soil and the structure.
- Drywood termites, which do not require soil contact, are more commonly found in roof structures or upper levels of a building.
- Additional signs can include damaged or weakened wood that sounds hollow when tapped or stepped on.
What you can do to help
If you notice flying or swarming termites on your commercial property, contact Rentokil promptly for a professional assessment. Early detection is critical to limiting damage and reducing risk. You can also ask your Rentokil technician about a termite baiting and monitoring program, which can help detect termite activity early and provide ongoing insight into potential threats before they impact your property.
Tips for prevention
Effective commercial termite prevention focuses on reducing conditions that can attract termites and make structures vulnerable to infestation.
- Repair plumbing issues, leaks, and moisture problems promptly.
- Monitor and correct condensation issues around HVAC and air conditioning units.
- Avoid wood-to-soil contact on the property, including posts, siding, and exterior features.
- Keep mulch pulled back from building foundations.
- Remove excess wood from the exterior, including construction materials, fallen trees, stumps, and roots.
- Use treated wood for all outdoor construction projects that are exposed to weather.
ID and biology
Termites can look different at different stages of development. Swarmers, or reproductives, are termites that have wings and are often mistaken for flying ants. Termite swarmers have straight antennae, two pairs of wings of equal length, and a uniform body with no narrow “waist.” Knowing these differences can help identify swarmers during mating flights. Termite appearance can vary based on the type of work the termite does within the colony.
Different roles of termites
Termites are highly social insects, organized into three distinct castes: workers, soldiers, and reproductive swarmers. Understanding how these colonies function is key to effectively protecting your business from costly damage.
Workers
Identification
- White
- Soft-bodied
- Wingless
- Most abundant of the termite types
What they do
- Primary labor force of a colony
- Build tunnels and clear galleries
- Tend to eggs and young
- Acquire food
- Care for and repair the nest
Soldiers
Identification
- Large head
- Two large jaws
- Wingless
What they do
- Protect the colony from pest invaders
- Stand guard to allow swarmers to emerge
- Use their jaws to wound invaders
- Warn other termites of danger by banging their head against the side of galleries
- Some soldier termites can emit a white, glue-like liquid that incapacitates intruders
Reproductive swarmers
Identification
- Winged
- Have two pairs of wings of equal size
- Attracted to light
What they do
- Swarmers are sexually mature and emerge when a colony has grown large
- Emerge from holes in ground, wood, or cracks in structures
- Can swarm in large numbers
- Will drop their wings after they land and pair off to attempt to start a new colony
FAQs
You can take steps to help reduce the risk of termites at your business, but complete prevention requires professional support. Managing moisture, repairing leaks, avoiding wood-to-soil contact, and removing excess wood from the property can help make your building less attractive to termites.
There are no proven natural methods that reliably keep termites away from a business. While certain conditions can discourage termite activity, such as those mentioned above, these measures do not eliminate colonies. However, termites can still travel underground or within structures without visible signs, which is why natural deterrents alone are not a dependable long-term solution for commercial properties.
Even with the best construction practices and ongoing maintenance, termites can still find ways to access a structure over time. That’s why professional commercial termite prevention and control is essential. Regular inspections and expertly managed prevention programs can help reduce risk, identify activity early, and protect your commercial property from costly damage over time.
