How to prevent and treat termite infestations?
Covers subterranean vs drywood termites, liquid barrier treatments (Termidor/fipronil), bait systems (Sentricon, Trelona), signs of infestation, DIY limitations, professional treatment options, inspection frequency, and prevention strategies. Based on university extension and USDA Forest Service research.
- Schedule annual professional termite inspections5
Have a licensed pest control professional inspect your home for termites at least once a year, preferably in spring during swarming season. Get inspections from 2-3 companies for comparison. Each should provide detailed findings and recommendations without pressure tactics.

🛠️ None
- Treat localized drywood infestations with spot treatment3
For small, accessible drywood termite infestations limited to a single area of wood, a pest control professional can apply localized treatment — injecting termiticide directly into the infested wood through drilled holes, or using heat or microwave treatment on the affected area.

- Do not attempt DIY treatment on active infestations5
If you discover an active termite infestation, call a licensed professional rather than attempting DIY treatment. Use the time before the appointment to get quotes from 2-3 companies and research their reputations.

- Remove dead wood, stumps, and debris near the house4
Remove dead tree stumps, scrap wood, fallen branches, and cellulose debris from within 20 feet of the home. Do not stack firewood against the house or on the ground near the foundation. Clear construction debris, cardboard, and paper products from crawlspaces.

- Fix moisture problems and leaky pipes5
Repair all water leaks — plumbing, roofing, gutters, and condensation from HVAC systems. Ensure proper drainage away from the foundation. Keep gutters clean and direct downspouts at least 3 feet from the house. Ventilate crawlspaces to reduce humidity.

- Reduce wood-to-soil contact around the foundation5
Maintain at least 6 inches of clearance between soil and any wood in the structure. Remove wooden lattice, trellises, or siding that touches the ground. Replace wood mulch within 6 inches of the foundation with gravel or rubber mulch. Ensure fence posts, deck supports, and porch columns use…

- Use a bait monitoring system (Sentricon, Trelona)4
Have a certified pest control professional install a termite bait monitoring system around your property perimeter. Sentricon Always Active uses noviflumuron (an IGR that inhibits molting). Trelona ATBS uses novaluron. Stations are checked and maintained on a regular schedule.

- Install a liquid barrier treatment (Termidor/fipronil)5
Hire a licensed pest control professional to apply a liquid termiticide barrier around your home's foundation. Termidor SC (fipronil) is the industry standard — a non-repellent termiticide applied by trenching 6 inches deep around the perimeter and drilling through concrete slabs where needed.
