How to Use Suspend SC Insecticide Concentrate by Bayer

 

Using Suspend SC Insecticide Concentrate is straightforward if you follow the correct steps, stay safe, and make accurate measurements. Here is a clear, in-depth guide for using Suspend SC in and around homes, carefully explained for those unfamiliar with pest control products.

 

Prepare Your Area Before Application

 

• Remove pets, children, and food from the area to be treated. Cover fish tanks or aquariums tightly.
• Ensure open windows and good ventilation if applying indoors.
• Check for people or pets outside if you will treat exteriors.
• Wear gloves and long-sleeved clothing to protect your skin from accidental splashes.

 

Gather What You Need

 

• Suspend SC Insecticide Concentrate
• Clean sprayer (hand pump or backpack style)
• Water
• Measuring tool (often 0.25–1.5 oz will be used per gallon; check label for your pest and location)
• Protective gloves and clothing
• Clean water source and mild soap (to clean equipment after use)

 

Mix the Solution

 

• Shake the Suspend SC bottle well so the ingredients are evenly mixed. Concentrates need agitation—don’t skip this step.
• Fill your sprayer with half the required amount of water.
• Add the precise amount of Suspend SC according to label instructions. For most insects indoors: 0.25–0.75 oz per gallon of water. For tougher pests or exterior use, you may use up to 1.5 oz per gallon. Read your product’s label carefully.
• Add the rest of the water up to the 1-gallon mark (or as much as needed).
• Close the sprayer tightly and shake or pump the tank to mix the product thoroughly.

 

Apply to Target Areas Correctly

 

• Spray baseboards, cracks, crevices, underneath sinks, around windows and doors, and other places you’ve seen pests or where they may enter.
• For exterior use, treat the foundation, exterior walls (up to 2–3 feet), around entry points, and places where pests may hide (garages, sheds).
• Use a steady, low-pressure spray. Avoid soaking surfaces—just a light coating is needed; over-application will not increase effectiveness but may cause issues.
• Do not apply to food prep surfaces, dishes, cooking utensils, or directly onto animals or plants you wish to keep (avoid flowers and beneficial plants).

 

Let Treated Surfaces Dry

 

• Allow all treated areas to dry before anyone—especially children or pets—returns to the area. This usually takes an hour or two.
• Once dry, Suspend SC leaves an invisible residue that continues working against pests for weeks.

 

Store and Clean Up Safely

 

• Clean your sprayer with mild soap and plenty of water until no visible residue remains.
• Rinse gloves and any protective gear used. Wash your hands thoroughly, even if you wore gloves.
• Store remaining Suspend SC tightly closed, upright, and out of reach of children and pets, in its original container.
• Dispose of rinse water and residues according to local hazardous waste guidelines—never pour down household drains or into the street.

 

Tips for Better Results and Safety

 

• Read the product label in full before starting. This is for your safety and effective use.
• Do not apply more often than the label permits—usually every 21–30 days if needed.
• Do not apply Suspend SC to areas where water can carry it into drains, sewers, or bodies of water—it’s for stationary surfaces.
• Do not use in rooms where infants, pregnant people, or people with respiratory issues may be exposed soon after use (wait for surfaces to dry and air out fully).

 

 

What Is Suspend SC Insecticide Concentrate by Bayer?

 

Suspend SC Insecticide Concentrate is a professional-grade liquid insecticide made by Bayer, intended to control a wide range of household and commercial pests. It is a suspension concentrate, which means it consists of small solid particles of the active ingredient mixed evenly in water, creating a liquid solution that can be sprayed. The main ingredient is Deltamethrin, a synthetic version of a natural insect-fighting compound called pyrethrin, which comes from chrysanthemum flowers. Specifically, Suspend SC is designed to be highly effective against crawling and flying insects, while being safe enough for use in and around homes, businesses, food-handling facilities, and other structures when instructions are followed.

 

Active Ingredient and How It Works

 

The active ingredient in Suspend SC is Deltamethrin. Deltamethrin is a type of chemical called a "pyrethroid." Pyrethroids work by attacking the nervous systems of insects. Once insects come into contact with surfaces treated with Suspend SC, or ingest it, they become paralyzed and die shortly afterwards. This action is specific to insects and, when used as directed, poses a very low risk to humans and pets.

 

What Makes Suspend SC Special?

 

• Long-Lasting Residual Effect: Unlike many other sprays, Suspend SC leaves a microscopic layer on surfaces that continues working for weeks or even months. Insects that crawl across these treated surfaces pick up the substance on their bodies, even if the spray has dried.
• Broad Range of Control: It targets a wide list of pests including ants, cockroaches, spiders, fleas, ticks, bed bugs, mosquitoes, wasps, flies, and more. This makes it versatile for residential, commercial, or industrial use.
• Low Odor and Staining: Suspend SC is nearly odorless and, because it is water-based rather than oil-based, it usually does not stain surfaces or leave behind visible residue. It dries clear.
• Professional Strength, Household Safe: Many pest control companies use Suspend SC because of its effectiveness and safety profile. Homeowners can purchase and use it as well, provided they carefully follow label instructions.

 

Physical Form and How It’s Sold

 

Suspend SC is sold in concentrated liquid form, meaning it must be diluted with water before use. It comes in bottles of various sizes (commonly 16 oz, 1 pint, or larger containers), with measuring tools or instructions on how much to mix for different purposes. After dilution, the mixture is typically sprayed onto surfaces where pests are a problem or where they may enter.

 

Where Suspend SC Is Used

 

Suspend SC is commonly used in:

• Homes (indoors and outdoors)
• Offices and businesses
• Warehouses and factories
• Restaurants, grocery stores, food processing areas
• Hotels and hospitals
• Schools and daycares (with due caution)

It’s applied to surfaces like baseboards, corners, cracks, entry points, and exterior perimeters—anywhere insects are likely to crawl or hide.

 

Safety Considerations

 

Suspend SC is considered low in toxicity when used according to directions. It is designed not to harm humans or pets after it has dried, and it breaks down over time in the environment. However, it is important to avoid direct contact before it dries, and not to apply it directly where food is prepared or on pets. The product should always be kept out of reach of children and animals before it has dried.

 

Summary

 

Suspend SC Insecticide Concentrate by Bayer is a specialist-grade, water-based insect-killing liquid used by professionals and homeowners. Its main strength is killing and repelling a wide variety of pests, using the active ingredient Deltamethrin, which attacks the nervous system of insects. Its long-lasting, low-odor, and non-staining properties make it a preferred and reliable choice for ongoing pest control in homes and businesses.
