Premise 2 Insecticide by Bayer, are among our top picks for long-lasting, effective termite control. Premise 2 is generally used for treating localized areas of known subterranean termite activity, but it is also effective in controlling drywood and dampwood termites, borers and other wood-infesting insects in and around basements, attics, crawl spaces, voids, and damaged wood piles.
Premise 2 is an excellent for trenching and soil drenching, foaming, or for treating wood. Premise 2 works differently from other termiticide products that are designed to simply repel or keep termites away from the treated soil area without killing them. Premise 2 is a non-repellent termiticide, meaning that termites do not detect that Premise 2 is present. Premise 2 creates an undetectable treated zone around the home, where termites unknowingly eat treated cellulose or tunnel into treated soil. The exposed termites then remain unaffected for a few days, before sudden death occurs.
In the meantime, the exposed termites are able to spread the Premise 2 chemical to unexposed termites by physical contact when they feed or groom the other termites, resulting in a domino death effect which wipes out more of the colony. Imidacloprid, the active ingredient in Premise 2, is the most widely used insecticide in the world with a proven track record of success - less than one percent retreat rate.

Subterranean termites, drywood termites, wood-infesting beetles, ants
Subterranean termites, carpenter ants, drywood termites, dampwood termites, wood-infesting beetles or borers (such as powder post beetles, anobiid or deathwatch beetles, false powder post beetles, old house borers, wharf borers, ambrosia or bark beetles); carpenter bees; ants; aerial nests in tree hollows or non-structural wooden construction
Premise 2 Termiticide is an excellent product for trenching and soil drenching, foaming, or for treating wood. Premise 2 is one of the most trusted insecticides for pre- and post-construction subterranean termite treatments, but it can also be used for most other wood-destroying pests. Use Premise 2 to treat localized infestations of drywood termites, carpenter ants, carpenter bees, wood-infesting beetles, and even aerial termite nests on structures or in trees or non-structural wood. Premise 2 Insecticide comes in a liquid formulation convenient for smaller jobs, spot treatments, or foam dilutions. Premise 2 can also be used as a perimeter spray for many types of ants and to protect firewood or other wood products store in contact with soil from carpenter and termites.
Indoor applications are limited to void treatments for active infestations of listed pests. For small void treatments, consider the convenient formulation of ready-to-use Premise Foam.
The purpose of chemical soil treatment for termite control is to establish a continuous chemical treated zone (horizontal and/or vertical as needed) between the wood and other cellulose material in the structure and the termite colonies in the soil. Use a 0.05% to 0.1% dilution based on local recommendations. Where severe or persistent infestations occur, a 0.1% dilution may be used.
For post-construction subterranean termite treatments, apply 4 gallons of a 0.1% solution per 10 lineal feet in a 6 in. x 6 in. trench around the perimeter of the structure to be treated. In areas where concrete is adjacent to the foundation, such as garages, driveways, etc., use a ½” in. x 18” hammer drill bit to drill holes 10”-12” apart and apply finished dilution termiticide at the same rate of 4 gallons per 10 lineal feet. See our article How to Do a Termite Treatment for more information.
For pre-construction concrete slab-on-ground or basements, apply an overall treatment to the entire surface of soil or other substrate to be covered by the slab including areas to be under carports, porches, basement floor and entrance platforms. Apply at the rate of 1 gallon of solution to accurately and uniformly cover 10 square feet. If fill under slab is gravel or other coarse aggregate, apply at the rate of 1.5 gallons or sufficient volume of solution to accurate and uniformly cover 10 sq. ft. In addition, apply 4 gallons of solution per 10 lineal feet to provide a uniform treated zone in soil at critical areas such as along the inside of foundation walls, and around plumbing, bath traps, utility services, and other features that will penetrate the slab.
In situations where necessary, conventional application methods can be supplemented through use of foam generating equipment, or similar devices, to provide a continuous treated zone. Foam application may be made alone or in combination with conventional application methods, provided that the labeled amount of active ingredient per unit area is used. See Mixing Table for Premise 2 Insecticide Foam on p. 32 of product label for more details.
Each 8 oz. bottle of concentrate yields 15 to 30 gallons of finished solution.
Standard Application Dilution Rates / Mixing Ratios:
8 ml (0.27 fl. oz.)/ gal. of water – 0.05% - lower infestations
16 mL (0.54 fl. oz.)/gal. of water – 0.10% - most termite applications, severe infestations of wood-infesting pests
For use in the following areas:
Pre- and post-construction termite treatments in residential, commercial, and industrial buildings; termites in trees, utility poles, fencing and decking materials, landscape timbers and similar non-structural wood-to-soil contacts; structural voids, crawl spaces, hollow block foundations
Indoor application is limited to spot treatment of active termite infestations in high risk areas such as plumbing and utility penetrations, along settlement cracks and expansion joints, and dirt-filled porches, and void treatments using injection of sprays, mists or foams into above ground structural voids, termite carton nests, and other infested locations.
For properties with wells or cisterns inside foundations: Do not apply within 5 feet of any well or cistern. Treat soil between 5 and 10 feet from the well or cistern by the backfill method only.
For control of ants in houses and other structures: Apply a 0.05 to 0.1% solution as a general surface, spot, crack and crevice or wall void application. Apply to surfaces on buildings, porches, patios and other structures, around doors and windows, eaves and attic vents, utility entry points, soffit areas and other exterior openings where these pests enter the structure or where they crawl or hide. Spray into cracks and crevices. Treat soil, turf, or ground cover adjacent to the structure where ants are trailing or may find food or harborage. Apply to flower, shrub, or ornamental plant beds adjacent to the structure where ants may find food or forage. Maximum application is once per month to maintain control.
Premise 2 Termiticide Features
Non-repellent treatment, undetectable “Treated Zone” around structures
The original Imidacloprid termiticide
Use for other wood-infesting pests such as carpenter ants, carpenter bees, and wood-infesting beetles
May be converted to a foam for void or hollow block treatments
Shake well before using.
Keep children and pets out of treatment area until treatment has dried.
Do not use against native or imported fire ants, pharaoh, or harvester ants.
Before beginning a treatment, determine the location of underground utility lines, the main water line shut-off valve, and if there is radiant heat or sub-slab air ducts.
In heavy clay soils, rod holes should be spaced 3-4 inches apart. In lighter and sandy soils, rod holes can be spaced 6-8 inches apart.
Where the soil is heavy, PREMISE 75 can be applied by reducing hole spacing, or by increasing the concentrations of Premise 75 two-fold in half the volume.
Houses that have large settlement voids or sand fill should be treated by long rodding underneath the slab.
Technicians should determine if air ducts in slabs are a perimeter system or a radial system before drilling and treating. Perimeter systems that run along the foundation can complicate treatment.
Ducts made of cardboard, or that have rusted out, should be sealed, and a recommendation should be made to the homeowner to install an alternate system.
Foaming void areas is an effective way to obtain complete coverage.
Do not treat soil beneath structures that contain cisterns or wells. Consult state and local specifications for recommended distances of wells from the treated area.
A borascope is a useful tool for determining what is located beneath a slab or behind a foundation wall.
I spoke to to few pest control people and they all say that they prefer this product for subterranean termites and drywood termites then other products, I save myself some money buying this and doing it myself.
It's likely that people become deeply concerned when they find out they have subterranean termites and don't know what to do. We felt this way. However, we researched and found this to be a wonderful and EASY treatment for subterranean termites! We've used Chinese chemicals before, and they are worthless. Bayer is a product we chose to try because we respect their quality control. Turns out to be a great choice! We mixed the heaviest strength as indicated and used a small hand sprayer around the perimeter of the house. They were EVERYWHERE and had done extensive damage. Three days later, not a termite in sight! Could not be happier!
great product. glad I was still able to buy it. kills the hell out of termites and seems to last forever. last area was treated 20 years ago and still no sign of termites. thanks again. hope I have the same results again on a new infestation.
Well I purchased the product with the intention that i will get rid of termites which I haven't used yet, but I sprayed some on an Ant colony that were really a pest, and it really worked. I was amazed with the results. I recommend this product 100%. i will expect the same result with the termites.
Will Premise penetrate wood and protect against termites?
I have been told by a pest control company that Premise will penetrate untreated wood, up to 1/8th of an inch, enhancing its exposure to termite infestations within post, beam, or stud. Can you corroborate this? Or is this an inaccurate claim?
I do not believe that is accurate. Premise Termiticide is a soil treatment meant to be placed into the ground. It will last for 5 - 7 years when placed correctly into the soil. Although you could spray wood with Premise and it may penetrate slightly into the wood and kill termites if they were present, Premise will not last long term on wood because it is not meant to. There is a product made for wood treatment that will pentrate through the entire piece of wood and remain in the wood and protect it forever, and it is called Bora-Care. It is very popular and widely used by pest control professionals. If the company you speak of was going to go through the trouble of spraying the wood anyways then they should use Bora-Care.
How do I mix Premise 2 and apply it for a termite trench treatment?
i have 1 gallon sprayer would like to apply to trench around my foundation what is the mixing ratio and is poison in liquid or powder form? does the trench need to be flooded? maybe using a 5 gallon bucket.
Please take a few moments to read our article How to do a Termite Treatment. This article will tell you in detail exactly how to do a liquid termite treatment and it will describe any and all equipment you will need. For typical termite barrier treatments you will use 8ml of Premise 2 per gallon of water and you will use 4 gallons of this solution for every 10 linear feet of trench.
Can I combine Permise 2 with ProFoam to create multi-year lasting treatment inside a hollow block wall?
Example: as a longer lasting alternative to immeadiate kill foams like Premise 2 Foam.
Potenitally even as an alternative tretment to trenching and drilling where the entire perimeter can be accessed via the block wall
Premise 2 is meant for treatment in the soil and is made to bond to soil. It will not last on wood for a long period of time. Maybe 2 to 3 months. You should foam with Bora-Care which is a wood treatment product. Bora-Care will last in the wood forever.
What is the difference between Premise and Dominion 2L?
I want to know why this product uses the same active ingredient.
Premise and Dominion 2L contain the same active ingredient. They are made by different manufacturers but the both are non-repellent liquid termiticides. They last approximately 7 years in the soil. Either would be a great choice for trenching for termites.
