Termidor SC Fipronil Insecticide / Termiticide

Termidor SC Termiticide insecticide, manufactured by BASF, is an effective, long-lasting termite colony treatment solution. Its active ingredient, fipronil 9.1%, provides effective results through the active's unique systemic transfer effect.

Termidor can control 100% of termite species within 3 months and will continue to control termites and other pests for extended periods.

As a low-odor, non-repellent insecticide for termite or ant control, pests such as subterranean termites, carpenter ants, and others will unknowingly come into contact with it and spread it to other colony members through contact or food sharing, resulting in total colony elimination.

Termidor SC termiticide insecticide also controls other common pests, such as cockroaches, spiders, carpenter ants, ticks, and more, within 90 days. When used as an in-ground barrier treatment, it will protect your home or business for up to 10 years from future termite infestations.

As a flexible product with a broad label, it can be used for pre and post-construction termite applications and exterior perimeter pest control treatment, including termite trenching, sub-slab injections, structural void applications, and exterior surface spraying without damaging water-safe surfaces

Tools Needed

To apply Termidor SC as a termite treatment, you will need a handheld pump sprayer, a backpack sprayer, or a spray rig for large-volume applications. You will also need a pickaxe or shovel to dig the trench and a bucket with at least a 5-gallon capacity to mix and apply the product. 

Do not use this product in a spray tank with borate contaminants.

How to Apply Termidor SC

• Step 1: Determine how much Termidor SC to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment areas' length and width in feet, then multiply them together (length X width = square feet). For termite trenching, measure the perimeter of the structure in feet. Termidor SC can be mixed between 0.4 fluid ounces per gallon of water and 1.6 fluid ounces per gallon of water, depending on the desired dilution ratio. We recommend using 0.8 fluid ounces per gallon of water for a 0.06% dilution for most applications. For general exterior surface spraying, a one-gallon dilution will treat about 1,000 square feet. For termite trenching, you will need 4 gallons of dilution to treat 10 linear feet.
• Step 2: For exterior surface applications with a one-gallon sprayer, fill your sprayer about a quarter of the way full. Then, add 0.8 fluid ounces of Termidor SC to the tank. Fill the sprayer the rest of the way with water to the one-gallon mark, and then shake the sprayer to agitate and create a thorough mix. Mix 0.8 fluid ounces per gallon of water in a bucket up to 4 gallons for termite trenching applications. It is easier to use a 5-gallon bucket so that it will not be filled to the brim and will help prevent spilling. To create a 4-gallon solution, you will need 3.2 fl. oz. (0.8 fl. oz. per gallon of water).
• Step 3: For use as an outdoor termite control, apply Termidor SC as a low-pressure, coarse spray. Spray up to an 18-inch wide band around common insect entry points, such as around doors, windows, and vents, where plumbing penetrates the walls, and wires enter the structure, and any other openings. Also, treat the perimeter of the house or structure by spraying where the ground meets the foundation, spraying one foot up the structure and one foot out. Dig a trench around the structure’s perimeter 6 inches wide and 6 inches deep for termite trenching applications. Hang on to the displaced soil, which will be used to backfill the trench after application. Because you will be applying 4 gallons of solution per 10 linear feet, creating a dam with the soil every 10 feet of the trench is helpful to section off each 10-foot stretch. Pour your finished termite control mix into each 10-foot stretch. Then, backfill by replacing the displaced soil. Be sure to pack the soil down for adequate distribution.

Where to Use

Termidor SC can treat pre- and post-construction of commercial, industrial, institutional, and residential structures and utility enclosures. It can be used on exterior surfaces, voids, above-ground termite infestations, exterior crawl spaces, perimeter trenches, under concrete slabs, and interior wall voids.

This pest control product may also be used for crawl spaces, basements, concrete slabs on the ground or in basements (including monolithic/floating/supported concrete slabs), hollow block foundations/voids, structures with French drains and sump pumps, structures with wells or cisterns, plenum construction, and garages (attached garage floors should be treated in structures).

Termidor SC cannot be used indoors unless limited to vulnerable areas such as around plumbing/utility lines penetrating floors, shower pan drains, bath traps, or along expansion joints or settlement cracks.

However, if known termite activity exists (as described at the beginning of the Post-construction Exterior Perimeter/Localized Interior (EP/LI) Structural Termite Treatments section of the Termidor SC Label) in areas on the interior of the structure's living spaces (i.e., occupied areas of the structure) or non-living spaces (e.g., crawl spaces, plenums), a localized interior treatment must be made at the site of the termite activity and at least 2 feet in two or more directions radiating from the site.

Do not contaminate wells or cisterns.

This ant control product cannot be applied to air conditioning units, air intake vents, playground equipment, pet quarters, and boat houses, including piers or pilings.

When to Use

Use Termidor SC to treat and prevent termites, carpenter ants and other listed pests. Apply on calm days when rain is not in the immediate forecast. Do not treat water-saturated or frozen soil.

Termidor can only be applied two times per calendar year at a 0.06% dilution for general ant or pest control.

Safety Information

Termidor SC is safe to use around pets and children when applied according to the product label instructions. Always wear the appropriate personal protective equipment (PPE) when mixing and applying this product.

Do not allow residents, children, or pets to contact treated areas or reoccupy treated areas until the spray has dried.

Do not treat within a distance of one foot out from edible plants.

Special Considerations

For best results, remove or prune away bushes, shrubbery, and tree branches touching the structure. Vegetation touching the structure may be a route of entry for pests, which may allow pests to inhabit the structure without coming in contact with Termidor SC Termiticide insecticide.

Termidor SC has been granted FIFRA Section 18 Quarantine Exemption to control tawny crazy ants in some Texas, Louisiana, and Mississippi counties. It can now be applied 3 feet up and 10 feet out from structural foundations and up to 10 feet around utility wires.
