Conquer Residual Insecticide, manufactured by Paragon, is an insecticide that contains the active ingredient Esfenvalerate, a powerful insect-killing chemical.

Conquer has a broad label and is versatile. It can be mixed with water or oil and safely applied as a space spray using a fogger.

Use it to control significant pests, including cockroaches, ants, fleas, ticks, stored-product pests, spiders, carpenter ants, and even deer ticks.

Tools Needed

You will need a hose-end sprayer, handheld pump sprayer, backpack sprayer, fogger, or spray rig. For small household jobs, we recommend a handheld 1-gallon pump sprayer or a 4-gallon backpack sprayer.

How to Use

Applying Conquer Indoors

  • Step 1: Determine how much Conquer Residual Insecticide you will need by measuring the square footage of the treatment area. You can do this by measuring the length and width of the treatment area in feet and then multiplying them together (length x width = square footage). The rate for Conquer Residual Insecticide is 1 to 2 fl. oz. in 1 gallon of water to treat 1,000 sq. ft. So, for example, if you have 3,000 sq. ft. to treat you will need to mix 3 to 6 oz. in 3 gallons of water to cover the entire area.
  • Step 2: Fill your sprayer halfway with the required amount of water and then add the appropriate amount of Conquer based on your calculations. Fill with the remaining half of the water, close the lid, and then agitate well to ensure the product is suspended.
  • Step 3: Apply the solution in cracks and crevices and directly to insect mounds as a perimeter barrier treatment around your home and spray in cracks and crevices.
  • Step 4: Repeat application as needed, but do not exceed more than one application every seven days in restaurants and similar food service establishments or more than one application every fourteen days in all types of food handling establishments.

Where to Use

Conquer can be used indoors and outdoors to control a wide range of pests. Use in and around homes as well as schools, warehouses, office buildings, apartment buildings, theatres, hotels, motels, kennels, food processing plants, food service establishments, truck trailers, railroad cars, and food manufacturing and warehousing establishments. Also, for use on lawns to Kill fleas and ticks. Focus your treatments around woodwork and floors, underneath sinks, areas behind pipes, and in all non-food contact places where these insects shelter.

When to Use

You should use this product when pest activity is high. For most areas of the country, this is between the spring and summer months. Apply the product quarterly for year-round control.

Keep pets and children out of the treated area until after the spray has dried.
