Termites: How to Identify and Control Them
How do I Know if I Have Termites?
The first step in prevention is to be on the alert for termites. Termites rarely emerge from soil, mud tubes, or food sources through which they are tunneling. Most people are not aware they have termites until they see a swarm or come across damage during construction. Some of the ways to discover if you have termites are listed below:
- Examine, by probing, exposed wood for hollow spots (using a flathead screwdriver or similar tool).
- Identify termite swarms (sometimes ant swarms are mistaken as termites).
Ants
- front wings longer than the hind wings
- antennae bent at ninety degree angle
Termites
- wings are roughly equal in length
- antennae are straight; may droop
How Can I Prevent Termite Infestation?
Make the Structure Less Attractive to Termites
During construction, use a concrete foundation and leave a ventilation space between the soil and wood. Cover exposed wood surfaces with a sealant or metal barrier.
Maintain the Termite Prevention Features
- After construction, keep the soil around the foundation dry through proper grading and drainage (including maintenance of gutters and downspouts).
- Reduce openings that offer termites access to the structure (filling cracks in cement foundations as well as around where utilities pass through the wall with cement, grout, or caulk).
- Fix leaks immediately.
- Keep vents free from blockage, including plants.
- Ensure that trees and shrubs are not planted too close to the structure and do not allow them to grow against exposed wood surfaces.
- Do not pile or store firewood or wood debris next to the house.
- Inspect periodically to help ensure that termite colonies do not become established.
Are Pesticides Used Against Termites Safe?
As the federal agency responsible for regulating all pesticides, including termiticides, sold, applied, or distributed in the United States, EPA must ensure that the pesticide, when used according to label directions, meets current safety standards to protect human health and the environment. To make such determinations, we require more than 100 different scientific studies and tests from applicants. Most states also review the pesticide label to ensure that it complies with federal labeling requirements and any additional state restrictions of use.
Many termiticides are highly toxic, making it critical to follow label directions with added care. Pest management professionals have the knowledge, expertise, and equipment as required by the label, which minimizes risks and maximizes effectiveness.
