CONDITIONS OF SALE: The directions for use of this product were determined through research to be appropriate for the correct use of this product. This product has been tested under different environmental conditions similar to those that are ordinary and customary where the product is to be used. Insufficient control of pests or plant injury may result from the occurrence of extraordinary or unusual conditions, or from failure to follow label directions. In addition, failure to follow label directions may cause injury to animals, man and damage to the environment. Bayer offers, and the buyer accepts and uses, this product subject to the conditions that extraordinary or unusual environmental conditions, or failure to follow label directions are beyond the control of Bayer and are, therefore, the responsibility of the buyer.

Do not formulate this product into other end-use products.


Use Credo® SC Insecticide as a general surface, spot, or crack and crevice treatment to floors, walls and support beams of poultry facilities.

Do not apply when birds are present. Cover or remove exposed feed and water from the area to be treated. Allow treated surfaces to dry before restocking/reintroducing birds into the facility.

MIXING AND APPLICATION RATES: Determine the area (number of square feet) to be treated. Refer to Mixing Table below for amount of Credo® SC Insecticide to be used. Mix the required amount of Credo® SC Insecticide with the appropriate amount of water and apply as a spray. Fill the sprayer tank with 1/2 of the water desired for the treatment. Begin agitating the water and add the required amount of product to the tank. Continue mixing and add the remaining water. Maintain sufficient agitation during product application to ensure a uniform spray.

Prepare a fresh spray mixture before each treatment.

MIXING TABLE for Credo® SC Insecticide

Pests to Control

Credo® SC Insecticide Per 1,000 ft 2

Gallons of Water Per 1,000 ft 2

Darkling Beetles
Hide Beetles

3 fl oz*
(90 mL*)

1/2-2 gallons

*Equivalent to 45 grams of imidacloprid a.i./1,000 ft2

CONVERSION KEY: 128 fl oz = 1 gal, 16 fl oz = 1 pint, 8 pints = 1 gal, 1 fl oz = 29.5 mL

WHEN TO APPLY: Apply between flocks, following de-caking/sanitation procedures.


Band Application: When darkling beetles are concentrated in certain areas, such as under feed or water lines, or along the perimeter walls, it may not be necessary to treat the entire poultry house. In these situations, certain portions of the house, or “bands,” may be treated. For example, apply diluted Credo® SC Insecticide to: a 3-foot wide band of litter under all of the feed and/or water lines in the house; a 3-foot wide band of litter adjacent to the side and end walls; and the lower section of the walls, including 1 foot up onto wood surfaces above the foundation. Be sure to measure the actual area (square feet) to be treated in order to determine the amount of Credo® SC Insecticide needed for the application.

Whole House Application: When darkling beetle infestation is severe, the entire house may need to be treated. Apply diluted Credo® SC Insecticide as a broadcast spray to the litter covering the entire floor area, especially to litter under feed and water lines, as well as to the lower sections of walls, including 1 foot up onto wood surfaces above the concrete foundation.

FOR BEST RESULTS: In houses with support beams, treat the litter surface around each support post, and 1 foot up each post. Also apply diluted spray to cracks and crevices around wall insulation, where beetles have been seen or can find harborage.

Resistance Management

Darkling beetles, like all insects, have the ability to develop resistance to insecticides. When a single chemical class is used continuously, this increases the likelihood that resistance to that chemical class will develop. Credo® SC Insecticide contains imidacloprid, which belongs to the class of chloronicotinyl insecticides. Credo® SC Insecticide should be used in an insecticide rotation program with other classes of insecticides including pyrethroids (such as Tempo® and Tempo® SC Ultra products), organophosphates and spinosyns, to prevent resistance and preserve the product’s effectiveness for darkling beetle control.

● Read and follow ALL label directions when using Credo® SC Insecticide or any other insecticide.

● Do not use Credo® SC Insecticide or any other insecticide product at lower than the recommended label rate. This exposes the insects to a sub-lethal dose and increases the development of resistance.

● Use Integrated Pest Management (IPM) strategies in addition to insecticide treatments to manage darkling beetle populations.

Contact your local Bayer Animal Health representative or your local Cooperative Extension Service for advice concerning the use of Credo® SC Insecticide and appropriate resistance management strategies.

NOTE: When pest exclusion at possible entry points is desired, supplement Credo® SC Insecticide treatments with targeted applications of pyrethroid insecticides (such as Tempo® SC Ultra or Tempo® 20 WP) to the building perimeter, foundation, doors and windows, utility entry points, and other places where pests may enter the structure. Read and follow all label directions for use of these other products.

Storage And Disposal
