My Experience

Suspend SC used to be one of the best pesticides. I used it for years and bragged about it to all of my friends. It works fantastic for fruit flies, spiders, roaches, ants, and termites. But, what about bed bugs?

At this point, even before I begin to elucidate the benefits of Suspend SC, let it be known that bed bugs develop pesticide resistance. It is less effective in areas where previously used in superabundance.

If your problem is any bug but bed bugs, then this is a pesticide to consider. If your problem is bed bugs, then where you live makes a difference. If you are from areas along the east coast, this may not be the right product for you.

An alternative for people along the east coast: Talstar Pro Review for Bed Bugs. Remember, I am not a professional exterminator. Only use this advice area where it is legal to do so. My review includes knowledge that I learned when buying and using the product.

I find Suspend SC worthy of inclusion in any bed bug extermination plan. This spray offers 3 months of continuous coverage with an invisible layer of killing power. This layer is not oily, and can not be seem by humans. Continue reading to learn how to use Suspend SC for bed bug infestations, and to see pictures of the step-by-step process.

Wen exterminating bed bugs, an investment must be made. Hopefully, through my reviews and other articles, you can devise a bed bug removal plan that will not cost you thousands and thousands. I did some calculations and, depending on your infestation, Suspend SC comes out to be around $3 -$4.00 a gallon.

Suspend SC Label and Packaging

When working with the community outreach project I purchased Suspend SC Insecticide from Amazon for around $40 USD. I opted for standard shipping, seeing as it is cheaper.

The seller was PestMall, which is an independent seller who sells through Amazon.

I was glad I did not upgrade my shipping, even though there was urgency to this purchase. The product arrived in 2 days with standard shipping, so there was no need to pay more. I had no problems with my purchase, but if I had I could have contacted either Amazon or Pest mall.

The product was mailed very discreetly. It came in a white, flat rate envelope lined with bubble wrap. Even though I selected the standard shipping, it was sent through the United States Postal Service as priority mail. I am not sure if this is available outside the U.S.

I did not need to sign for the package; it was left in my post box. Some states/countries might have different laws about shipping pesticides, so your experience may vary. Upon opening the envelope, there was a packing slip, receipt and a one pint bottle of Suspend SC in a sealed plastic bag, as can be seen in the picture to the right.

The Suspend SC label clearly states the name of the product, the word “Insecticide” and various cautions. Upon opening the sealed bag, I inspected the product, which was sealed properly.

To open the front label, peel it from the corner. It unfolds in to lengthy instructions. Be careful how you peel this off, it is prone to ripping if not done correctly.

I know you might want to jump right in and start mass murdering bed bugs, but you MUST stop and READ this insert before you begin! This insecticide is used for hundreds of different insects, such as bed bugs, termites, roaches, and other creepy crawlies.

Suspend SC is a concentrate, which means you will measure out certain portion and mix it in a one gallon insecticide spray bottle. The amount of concentrate use depends on your specific circumstances and is clearly charted on the label.

Not following the instructions could lead to overuse of the insecticide, or not using enough. The Suspend SC Label, the one on the back of the bottle, contains safety warnings and storage instructions. Be sure to read these, too. Once you have read the entire label, you will know how much you need to use for a bed bug infestation.

For bed bug infestations, you will use between .75-1.5 fl oz of Suspend SC per gallon (as stated on page 5 and 6 of the label). The amount you will use depends on the square footage that needs sprayed and the size of the infestation. The instructions indicate which amount is right for you.

Mixing Suspend SC

Suspend SC insecticide comes in one pint and one-gallon bottles. Most residential users will not need a one-gallon bottle.

From my experience, one pint will make about 12-16 gallons of bed bug killer, which is usually more than sufficient for bed bug infestations. To kill bed bugs with Suspend SC, you will need a 1-gallon sprayer, which is not included.

Spray gallon tanks are inexpensive. As a general rule of thumb, you should have a dedicated spray bottle for each type of pesticide. Label the bottle appropriately so there is no confusion.

I buy Chapin sprayers because they are made well and tend to last a long time. Both the Chapin Surespray and Chapin 2000 are excellent for spraying for bed bugs, as well as other pesky critters.

The spray bottle will have a handle which is used as a pump. This creates suction that will drive the insecticide in to the hose. At the end of the hose, there is a sprayer with a squeeze handle. When you squeeze the handle the insecticide comes out.

The nozzle on the sprayer can be adjusted for the flow that you require. On the side of the bottle there is a yellow pressure knob, (usually yellow). When you are finished using the sprayer, it might not open due to built up pressure. You will then need to turn the knob to vent the air and release the pressure.

When you vent the sprayer be very cautious! Making sure that it is held away from the face. When the air is vented, sometimes small particles of the insecticide are vented, too.

When finished make sure to close the valve, otherwise, it will not create suction for the next spray.

As you can see in the picture, there are two lids at the top of the Suspend SC Insecticide. One is for pouring out the concentrate, the one on the right. The other one is for measuring.

When I used this, I did not understand how to use the container. I used a pill bottle to pour the insecticide in the measuring side. This was wrong!

Later on, I noticed the channel on the left of the Suspend SC bottle, and fully read the instructions, which I am always telling my readers to do (bad me)! To fill the measuring cup on the left side you simply need to squeeze the bottle.

To fill the measuring cup on the left of the bottle remove the left cap, the one with the measuring cup. Keep the lid on the right on tight. As you squeeze, the concentrate will run up the channel and fill the measuring cup on the left.

If you do this the opposite way, with the lid on the right off and the one on the measuring cup on, then it will try to come out of the open lid. As long as you do this correctly, it only takes a gentle squeeze to fill the measuring cup.

If you squeeze too hard, or too quickly, you risk causing the Suspend SC concentrate to spill over the edges. If this happens was your hands quickly and carefully clean any spilled concentrate with a warm washcloth.

The measuring cup has two markers, one at .25 fl oz and one at .75 fl oz. In our situation, we usually need to use 1.5 fl oz, as directed on the Suspend SC label. This means squeezing the bottle, filling the measuring cup, pouring it in the one gallon sprayer, and doing it all again.

After this, you will add water to the one-gallon sprayer. The bottle will have a fill line. It is important to measure the water and Suspend SC carefully to assure you mix the solution correctly. Once you fill the gallon sprayer, you will pump the handle until enough pressure is created to use the spray handle.

How Well Does Suspend SC Insecticide Work

The active ingredient in Suspend SC insecticide is Deltamethrin. According to the University of Illinois Extensions “Illinois Pest Review”, bed bugs have the remarkable tendency to adapt. Some strains are killed easily with Deltramethrin where others are not.

So how do you tell if your bed bugs are the resistant strain? You can’t, and neither can a professional exterminator. Unless you have an exterminator who will send samples of your dead bed bugs to a lab, you just won’t know. I wonder what a DNA analyses of a bed bug costs!

You might be asking, even if Deltramethrin works, won’t my strain become resistant? In short, yes. This is why you must prioritize your bed bug infestation. Spraying alone will not kill them.

You need to take other steps, as well. The quicker to kill all of the bed bugs, the less spray you need to use. You want to use as little insecticides as possible to prevent future bug generations from growing resistant. This is why you need an integrated bed bug plan.

If you fail to kill all of the bed bugs, you may get into trouble. The major point here is: don’t put it off. If you don’t spend money and time attacking right now, you will spend 50 times the money and time later. If you do use Deltramethrin and it works, great. If not, you need a product with a different active ingredient.

To prevent resistance, you might use Suspend SC, with Deltramethrin for six months, and then switch to something else. I suggest doing upkeep (in-between sprays) with an organic product, such as BedBugBully. Switching between Deltramethrin and an organic insecticide can help prevent the bed bugs from growing resistant, while keeping your family safe.

I would not suggest switching back and forth between certain insecticides quickly, unless the label says you can do so (most don't). You do not want to create a lethal, or dangerous, combination, or overdose someone on insecticide, which looks like heat stroke with the runs.

Suspend SC allows for 1 spraying every three months. If you find you need more, then use something organic. When the time period specified on the label of the bed bug spray is up, then you can switch to try a new product.

Trust me, I once sprayed one product and three weeks later another product. The result was fumes which caused skin burns under my eyes. I find that Suspend SC is fairly safe as long as you follow the instructions.

There have been no problems with this spray and pets in my experience, although I would not recommend spraying Suspend SC on pet beds. In the Hub "Bed Bugs and Cats", there are special instructions on how to treat cat beds, and the same method will work for dogs.

You may use different types of products. Such as using Suspend SC Spray and Delta Dust, keep in mind that Delta Dust is flammable.

I HIGHLY recommend you purchase Demascus Earth (Diatomaceous Earth). After you spray sprinkle it under mattresses, couch cushions and behind beds, dressers and other furniture. They key is to place the diatomaceous earth any place you did not spray.

You also need bed bug proof mattress covers. Once you finish spraying, seal all mattresses up tight.

Additional Information and My Thoughts about Suspend SC

Some people say you have to spray Suspend SC on a bed bug directly to kill it. In some cases, you can spray it directly, and it will still gut up walk away, but it will not likely live to bite another day. I have experimented with bed bugs I put in jars and learned that they will eventually die (don't call PETA).

The same is true of the film Suspend SC leaves. In my experience, most strains, especially in the U.S. and Canada, are not Deltramethrin resistant... yet. It works, but it can take a few hours or days, giving the bugs enough time to get out of sight before they die.

Between the first and second spray, you should wait two weeks, after that you should spray every 3 months. This second spray is to make sure there is a fresh coat out for any newly hatched eggs. Keep in mind, if you do not do more than spray, this will all be a waste of time.

I have witnessed bed bugs avoiding areas that have been sprayed with Suspend SC. So, you want to use this spray in tandem with a thorough cleaning, de-clutering, and covering mattresses and pillows with zippered covers.

I have also seen some tenants repaint furniture, and we have repainted and sealed walls. We have found repainting a bed frame can help seal the frame, preventing any young bed bugs from leaving small pores and cracks.

After you spray Suspend SC you should seal up any cracks and crevices a bed bug nest could be hidden in. This can be a little time consuming, but is worth it. To learn more read the hub "Caulking and Sealing for Bed Bugs."

Suspend SC is an excellent bug bed spray, given that the strain you have is not resistant. The only way you will know if they are resistant is by trying this spray and the other methods mentioned. The added benefit of this spray is that it kills anything, and everything else. Plus, it can be used indoors, on mattresses and furniture, and outdoors. I would highly recommend this product to anyone.

      Thanks Maralexa. I am so glad you brought up Diatomaceous Earth! I plan to hub about that when I begin natural products. Back before bed bugs, our favorite way to keep roaches out of our properties was Diatomaceous Earth.

      For bed bugs it has its uses. For example, some of the houses my boss owns are really old. When doing one bed bug battle we discovered they were under the floor. In this situation Diatomaceous Earth was perfect.

      I have seen others use Delta Dust, and it works, but it is flammable which could create a safety hazard. Diatomaceous Earth is a lot safer.

      Bed Bugs are the worst! the very worst of bugs! thanks for this very detailed information. Have you ever tried Diatomaceous Earth? It is supposed to work in its pure organic state (not mixed with chemicals). I have even used hairspray to kill the visible ones. Oh how I hate bed bugs!

      Voted up, useful and interesting.
