How are subterranean termites treated?
Subterranean termites are treated by cutting off their route from the soil to the building, killing the colony or both. That can mean a liquid soil barrier around the foundation, bait stations that workers carry back to the colony, or direct treatment of infested wood. The choice depends on the building and the extent of activity.
A barrier works by making the soil next to the foundation unattractive or deadly to termites that cross it. Bait works more slowly but can reach a colony that is not near the house. Many jobs use one method with a spot treatment on wood.
Ask the technician why a method fits your building and what the follow-up looks like. A clear answer is part of the service.
How serious is a termite problem in Detroit?
A termite finding in Detroit deserves attention but not panic. Termites are native to southern Michigan, and Detroit is within their range near its northern edge. Damage can go unnoticed because it happens inside wood, so an inspection is worth having if you have seen swarmers, mud tubes or soft wood.
Termites work slowly, and a finding is rarely an emergency measured in hours. It is a decision about when to treat, not whether the house is about to fall. Still, a colony does not go away without treatment, so do not wait for years.
Our guide on whether termites are a real problem in Detroit goes through what is known and what is not.
What can I do to make termites less likely?
Keep wood away from soil, fix leaks and downspouts that spill at the foundation, and keep firewood and lumber off the ground and away from the house. Termites need moisture, so drainage and dry basements matter. These steps lower the odds but do not replace an inspection or treatment.
Cracked slab aprons and failed caulk at the foundation let water reach wood, and old stumps and buried wood near the house can feed a colony. A gutter that dumps at the wall every thaw can keep a sill damp.
If you are repairing a porch or adding a deck, ask the contractor to keep wood off the ground and above grade. It is cheaper to design around moisture than to fix it later.
- Direct downspouts away from the foundation
- Keep firewood, lumber and cardboard off the ground and away from walls
- Repair leaks, damp basements and failed caulk
- Remove stumps and buried wood near the house
Is termite damage covered by insurance?
Many homeowner policies exclude termite damage, because it is treated as preventable maintenance, but policies differ and we cannot say what yours covers. Check your policy and ask your agent directly. A written inspection report can help if you need to document what was found or sold.
Treatment prevents further damage but does not repair what has already happened. If wood is structurally weak, a carpenter or builder decides on repairs.
Keep any report, quote and receipt, because buyers, lenders and insurers may ask for them later.
What happens to damaged wood after treatment?
Treatment stops active termites but does not repair wood they have already damaged. A carpenter or builder decides whether a sill, joist or post needs replacing or sistering. The technician describes what was found and where, so a contractor can plan the repair, and moisture near the wood is dealt with at the same time.
Damaged wood that is sound enough to carry its load is sometimes left in place and monitored, while soft or hollow sections are replaced. The call belongs to the repair professional.
Keep a record of the technician's findings and any photos. They help the contractor, and buyers or lenders may ask for them later.
