Seeing a swarm of flying termites inside or around your home can be alarming, conjuring worries about hidden termite damage and growing populations. In this situation, many homeowners wonder, “How long do termites swarm?” While swarms are usually short-lived, it often depends on the season. If termites are swarming your home after receiving a termite treatment and repair service, it is because the company failed to properly apply the treatment.
What Is a Termite Swarm, and How Long Do They Last?
A termite swarm is when a colony releases a large group of reproductive termites to mate, nest, and establish new colonies. Colonies must be well-established in order to have swarmers.
So, seeing a termite swarm likely means there is a nearby colony that may be causing damage. The majority of swarms happen about 600-900 feet from the nest. Most termite swarms last between 30 and 40 minutes, though they can be longer depending on the size of the colony, what species of termite they are, and the weather conditions. Termite swarms tend to occur in the daytime on days with warmer temperatures and higher humidity levels.
Though the swarm itself is relatively short-lived, the termite swarming season can last for weeks or months. What time of year a colony swarms depends on the species, though swarms are most common during the spring and early summer, or after rainfall or high humidity.
Signs of a Termite Swarm to Look Out For
The signs of a termite swarm are relatively obvious. Many homeowners can see the flying swarms of termites around, or even in, their home. However, even if you are not there for the swarm itself, you may notice discarded wings. Termites often drop their wings near windows and doors. You may also see dead termites that were not able to return to the soil after the swarm.
If you notice a swarm, you should also check for signs of termite damage. Common signals of a termite damage case include:
- Mud tubes around foundations or walls
- Hollow-sounding wood
- Buckling floors
- Warped door and window frames
- Warped or blistered wood
What to Do When You Notice a Termite Swarm
In a termite damage case, do not wait to take action. Waiting can allow time for termite colonies to grow, worsening termite damage. Instead, take the following steps immediately:
- Take photos and videos of the termite swarms.
- Take photos and videos of any visible termite damage.
- Avoid disturbing evidence such as mud tubes or damaged areas.
- Schedule a professional inspection.
- Review your homeowners’ insurance and any existing termite warranties or treatment bonds.
- Notify the relevant company, such as your insurer or termite treatment and repair company, of the swarm.
- Keep any records, such as inspection reports, repair estimates, price quotes, or records of communication.
- Avoid treating the issue yourself, as you may damage evidence.
Many termite treatment and repair companies view having between 50 and 100 termites swarming in your home as a sign that there may be a termite colony. Working with a professional can help you understand the extent of termite damage in your home and how to treat the issue.
Handling a Termite Swarm That Occurs After Professional Termite Treatment or Repair
Sometimes, homeowners notice a termite swarm even after receiving professional termite treatment and repair services. In this situation, it is important to hire a termite damage lawyer as soon as possible. A termite damage attorney can help you identify whether the treatment company adhered to the state’s termite damage laws.
In many situations, a termite damage attorney can identify errors or oversights that leave the company liable for your damages. For example, if the company failed to repair the area where termites were entering the home, allowing future termites to grow a colony even after their treatment.
However, a termite damage claim is often denied. If this happens, a lawyer can help you identify the reason and pursue litigation to recover compensation.
FAQs
Do Termites Swarm Every Night?
Most termites do not swarm every night. Most species swarm during the daytime and can swarm every day during the spring or rainy season. However, certain termites do swarm at night and may swarm for multiple days in a row. In general, you can expect swarming to stop as the season changes and the weather becomes drier, though this does not mean you are not at risk for termite damage.
Where Do Termites Go After They Swarm?
After termites swarm, they often go back to the soil or soft wood to nest. If the termites cannot find a dark, damp location, such as the soil or wood, they can die quickly after swarming. Noticing where the swarms are, or where the termites go, can help you identify where they are nesting and if there is any termite damage in your home.
Hire a Termite Damage Lawyer You Can Count On
A termite swarm may only last for a short time, but the financial consequences and more serious damage can last much longer.
