Suspend SC Insecticide - Questions & Answers

You should use 1 ounce of Suspend SC for each gallon of water for general pest control outdoors.

Talstar P, Suspend SC and Demand CS have a shelf life of about 3-5 years from the date of purchase. They should be stored in a place where they are protected from over heating, freezing and direct sunlight to ensure the longest shelf life possible.

Yes, Suspend SC and all of our products are safe as long as you follow the instructions on the product label. When mixed with water, these products are only strong enough to kill small insects. You should keep all children and pets out of the room while you are treating. Use common sense when applying, you obviously do not want to spray on any toys or around pets food and water bowls. Wait 30 minutes for product to dry, then it is perfectly safe for children and pets to re-enter the room.

Most sprayer manufacturers warn against storing insecticides inside the sprayer. Storing liquids (even plain water) inside the sprayer can cause the rubber components to deteriorate quickly and make the sprayer inoperable. Only mix exactly what you can use and discard any left over solution and thoroughly rinse the sprayer after each use.

Suspend SC can applied to mattresses, especially tufts, folds, and edges until moist. You should also apply to the interior of the frame. Allow to dry before remaking bed.  Also, you would want to treat around the perimeter of the room, baseboards, feet of the bed, etc.  You may want to try one of our Bed Bug Kits which have a variety of products which are proven to treat bed bugs.

Tempo SC Ultra is formulated using the active ingredient beta-Cyfluthrin and Suspend SC is formulated using the active ingredient Deltamethrin. Both active ingredients are from the same class of insecticides known as synthetic pyrethroids and because of this both products are labeled for many of the same insects. Suspend SC does have a much broader product label and is allowed to be used in more places for more insects than the Tempo SC Ultra. Tempo SC Ultra on the other hand is known to have a bit of a faster knockdown and less chance of resistance because it has not been as widely used. Please take a moment to read over the Suspend SC product label and the Tempo SC Ultra product label to see which product would best fit your needs.

Suspend SC is not a contact kill. It does take some time to effect insects after they contact a treated surface.  They will die within a few hours up to 24 hours

Both the Suspend SC and the Talstar P contain synthetic pyrethroids for active ingredients and will provide very similar results. The only advantage to using Talstar P over Suspend SC is that it is known to be super gentle on most plants (do not use on edible vegetation) and is virtually odorless while Suspend Sc does have a slight odor. Both products can be used indoors and outdoors and both products are safe to use in houses with children and pets.

Suspend SC will kill mosquitoes. We recommend you spray your garage and also the bushes and trees around your home to control the mosquitoes.

Suspend Polyzone is the newer, better version of Suspend SC. Suspend Polyzone has a polymer added to its formulation that enable it to last 90 days outdoors and work better on porous surfaces. Suspend SC will only last about 30 days outdoors.

To treat for roaches we recommend spraying once every 21 days with suspend and also using a roach bait like Maxforce FC magnum. Apply the bait once a week. You want to bait high and spray low. Bait around counter tops, appliances, cabinets, bathrooms, etc. Please view our article on roach treatment.

Suspend SC is not the best choice for indoor flea control because you can not broadcast spray it over carpeted areas. We recommend using Ultracide for indoor fleas. Ultracide is a very effective flea control aerosol that provides immediate kill of adult fleas and prevents formation of new adults from eggs or larvae. Ultracide is a very safe and effective flea control product that is used widely by professional companies such as Terminix and Orkin in homes with children and pets all the time.  You should only apply Ultracide to carpeted areas and upholstered areas.  Do not apply on top of couches and chairs where people rest their arms, fleas do not breed in these areas. You would want to spray around the foot of the furniture, and underneath couch cushions.  You should have children and pets in another room while you are treating.  After treatment, allow 30 minutes to dry and then it is perfectly safe for children and pets to re-enter the room. Vacuum immediately before the treatment and every other day for the next 14 days. A second treatment may be needed after 14 days for heavy infestations.

Suspend SC is labeled for scorpion control. When using Suspend SC for scorpions, we do recommend using the highest concentration rate of 1.5 ounces per gallon of water.

Suspend SC is labeled for roaches, including German roaches, and should do a great job helping you eliminate the infestation. We recommend that in addition to a concentrated liquid insecticide like Suspend SC you also use a high quality roach bait gel such as Advion roach Bait Gel to help get the roaches that hide in places where you cannot spray (cabinets, counter tops, drawers) as well as an insect growth regulator such as Gentrol Point Source to help stop the breeding cycle of the roaches. You can purchase both of these products together in our Roach Control Kit #1.

Leftover product can be poured out right up against the foundation of your home or structure. You should clean the sprayer outside and dump the rinse water in the same place you poured out the excess product. Product and rinse water cannot be poured down the drain.

Suspend SC is one of the safest and most effective products we sell, which is why it is so popular.  You should always have children and pets vacate the room while you are applying the product.  Once the product is dry, which usually takes about 30-45 minutes, it is fine to allow children and pets back in the room.  These products are only strong enough to kill tiny insects.

Suspend SC can be mixed at 1.5 fl oz per gallon of water per 1,000 sq ft for a great residual solution on the exterior.

We would recommend washing your dishes if Suspend SC was sprayed in cabinets where they are stored. Your cabinets should be empty of dishes and food when this product is sprayed. 

Suspend SC and Suspend Polyzone are not considered a non repellent or a repellent. Deltamethrin, the active ingredient kill insects by direct contact of the areas that have been sprayed (wet or dry) or if they eat it (baits). It disrupts their normal nervous system function. 

The "SC" in Suspend SC is for suspended concentrate. Suspend Polyzone uses the same active ingredient but has a polymer coating around the active ingredient to better withstand weather elements, rain, sun, heat better. Suspend SC lasts for 30 days outdoors and Suspend Polyzone lasts 90 days outdoors. 

Suspend SC does not provide an instant knockdown. Suspend SC will kill wasps and other insects over a period of several hours after they contact treated areas. Suspend SC will leave a residual that will last up to 4 weeks outdoors and up to 12 weeks indoors. If you can directly treat a wasp nest you can expect the colony to be eliminated within several days. If you cannot directly treat the nest you will only be able to eliminate those wasps that are landing on the treated areas and you may not be able to gain 100% control. If you are indeed treating outdoors and within 2 feet of your home you may want to consider using Termidor SC. Termidor SC is a bit different than Suspend SC in that it can be transferred back to the wasps nest and through their normal social interactions they will spread the product through the nest. This product can take a week or two to eliminate the nest and it does not offer an instant knockdown. If you prefer an instant knockdown we do carry Wasp Freeze and Wasp X.
