How does a bait station work in the ground?
A bait station is a small housing set in the soil beside the foundation. It holds a cellulose material that termites feed on, and the bait is designed to be carried back to the colony over time. A technician checks each station on a set schedule to see whether feeding has begun.
The station sits in the ground because termites are already travelling through the soil to reach wood. The housing keeps the bait from drying out and shields it from weather, and a lid lets the technician open the station without digging.
Feeding is slow by design. The bait works through the colony rather than through one termite, so a station may show activity over several visits before it is cleared. A dramatic change in a single visit is not the expected result.
Stations are placed where termites are most likely to reach the building, usually near the foundation, the wood in the soil and any path a colony would take. Each position is part of the record, so the next visit can compare like with like.
- Stations are numbered and mapped
- Each visit is logged against its station number
- Bait is changed when feeding is found
When is baiting a better choice than a liquid barrier?
Baiting suits some homes better than a liquid barrier, particularly where the soil is hard to treat or an owner wants ongoing monitoring. A liquid barrier suits a home that needs a continuous treatment line along the foundation. The technician compares both on site before one is chosen.
Landscape and access shape the choice. Dense beds, paving against the foundation or a steep slope can make a continuous soil treatment hard to place, while stations can sit where a trench could not be dug.
A home with a past termite finding may suit monitoring. Ongoing checks show whether activity returns, and they leave a dated record that an owner, a lender or a buyer can read later.
Neither method replaces the site fixes. A station will not help a house whose gutters pour water against the foundation, so grading, gutters and wood contact belong in the plan whichever method is used.
What does a monitoring visit involve?
A monitoring visit opens each station, inspects the bait and the wood inside, and records the result. The technician also looks at the foundation and the landscape for changes since the last visit, then updates the plan and the record. The visit schedule is set when the program begins.
The technician checks for termites, for feeding on the bait and for any other insect that has entered a station. Each finding goes on the record against its station number.
The visit also covers the house itself. New mud tubes, a change in the landscape, a new pile of wood or a leak can all change the risk, and the technician notes them for the owner.
Keep the monitoring records in one folder. They are the history that a future inspector, lender or buyer is likely to ask for, and a gap in the visit log is hard to explain later.
- Ask for the station map and the visit log
- Report any new mud tubes or swarmers straight away
- Tell the technician about landscape work near the house
