Understanding Subterranean Termite Control
Informational Guide from Parish Pest Control
Subterranean termites are not a matter of if, but when. In Louisiana’s warm and humid climate, termite pressure is constant—and untreated structures are at high risk. Termites can cause thousands of dollars in structural damage, and costly repairs may be needed in addition to treatment.
Regulated by the Louisiana Department of Agriculture & Forestry
Termite control in Louisiana is strictly regulated. Our treatments are performed according to state-mandated guidelines to ensure the highest standards of safety and effectiveness.
Our Treatment Process
Trenching
We are required to dig a trench around the entire footprint of the structure before applying termiticide. This ensures a continuous barrier to prevent termite access.
Example: Trenching & Treating
Drilling
Drilling is performed every 12 inches along:
•Interior and exterior expansion joints
•Cracks within 12 inches of the base of the structure
This allows the termiticide to reach below slab areas where termites may travel.
Example: Drilling Performed
Bath Traps
Bath traps are 12×12 inch openings in the slab, usually under tubs and showers, where plumbing passes through. Termites can use these as hidden access points. At the owner’s discretion, we can:
• Create a 6-inch access opening
• Treat and inspect the area
• Cover the opening with a removable panel
Example: Bath Trap Panel Installation

Areas Typically Waived
To save our customers money, treatment is often waived around:
• Open carports
• Porches
• The front of metal garage doors
These areas do not typically offer subterranean access points.
Pricing
The cost of treatment is based on the linear footage of the structure. Per state regulation, 4 gallons of termiticide are applied every 10 linear feet.
Importance of Annual Contracts & Booster Treatments
Your initial treatment is only the beginning. We highly recommend maintaining your termite contract as it is the only effective way to protect your structure long-term.
• Contracts renew annually at the discretion of both the customer and the company
• A detailed inspection must be performed annually
• Annual renewal fees must be paid to maintain coverage
IMPORTANT: If your structure is not covered under an active termite contract and a termite issue arises, a full retreatment of the property will be required at full cost to the customer.
Booster Treatments
All termiticides break down over time. We perform a booster treatment every 10 years to ensure continued protection.
$250,000 Damage Repair Warranty
While your structure is under an active termite contract with Parish Pest Control, you are covered by our $250,000 Damage Repair Warranty.
If termite treatment fails and subterranean termites cause damage during the coverage period, we will cover qualified repairs—up to $250,000.
This warranty gives you peace of mind knowing your home or building is fully protected.
Annual Inspection Includes:
• Thorough visual inspection of the property
• Picture of your inspection diagram
• Detailed notes and treatment record
How Termite Treatments Work
Subterranean termites require a water source to survive. Assuming no roof or siding leaks, and with the perimeter properly treated, any termites attempting to establish an infestation must travel through treated soil, where they will be eliminated.
