Suspend SC Insecticide Review
What Bugs Does Suspend SC Really Work Against
Suspend SC used to be my favorite pesticide. I recommended it to my friends. It works fantastic for fruit flies, spiders, roaches, ants, and termites. The one bug that it may not work as well against is bed bugs.
If your problem is bed bugs, then where you live makes a difference. Bedbugs develop pesticide resistance. That makes this pesticide less effective in areas where it was previously used in superabundance. 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.
If you don't live on the East Coast, Suspend SC is worthy of inclusion in your 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 cannot be seen by humans. Suspend SC is around $45 per pint. Since you mix the product with water, each gallon of insecticide spray you make will cost from $3 to $4.
If your problem is any other bug but bed bugs, no matter where you live, then this is a pesticide to consider. 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.
My Experience With Ordering and Shipping
I bought Suspend SC while researching for a community outreach program.
Market: Amazon for around $40 USD.
Vendor: PestMall (Independent seller on Amazon)
- Suspend SC insecticide comes in one-pint and one-gallon bottles. Most residential users will not need a one-gallon bottle.
- Shipping: The product arrived in only 2 days with standard shipping. I had no problems with my purchase, but if I had I could have contacted either Amazon or PestMall.
- Package Upon Arrival: 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.
- 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.
Instructions On The Suspend SC Label
- To open the front label, peel it from the corner. It unfolds into lengthy instructions. Be careful how you peel as 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 types of 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 you use depends on your specific circumstances and is clearly charted on the label.
- Not following the instructions could lead to overuse, or not using enough. The Suspend SC Label, the one on the back of the bottle, contains safety warnings and storage instructions.
- 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 spraying and the size of the infestation. The instructions indicate which amount is right for you.
What Else You Need To Buy When Using Suspend SC Insecticide
Getting Prepared To Use Concentrated Pesticides
What you need with Suspend SC:
From my experience, one pint will make about 12-16 gallons of bed bug killer, which is usually more than sufficient.
To apply Suspend SC you need a 1-gallon sprayer, which is not included. Spray gallon tanks are inexpensive. The directions do not mention this, but 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 release valve on this sprayer is better than its competitor's.
The spray bottle will have a handle which is used as a pump. This creates suction that pushes the insecticide into the tubing. At the end of the tube, 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.
Mixing Suspend SC
There are two lids at the top of the bottle. The one on the right is for pouring out the concentrate, and the one on the left is for measuring the suspension. To fill the measuring cup on the left side, you simply need to squeeze the bottle.
I like that this product has its own built-in measuring system. 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 concentrate to spill over the edges. Wear gloves to protect your skin in case of spillage.
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 up to the .75 mark, pouring it in the one-gallon sprayer, and doing it all again. (.75 + .75 = 1.5.)
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 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 know if your bed bugs are the resistant strain? You can read review after review don't, but it is almost imposible to know which bug is resistent to which product. Unless you have an exterminator who will send samples of your dead bed bugs to a lab, you just don't know. I wonder what DNA analyses would cost!
- 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 you kill all of the bed bugs, the less spray you need to use. You want to use the least amount insecticide as possible to prevent future bug generations from becoming resistant. This is why you need an integrated bed bug plan.
- If you fail to kill them all off, 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 one spraying every three months. If you find you need more, then use something organic. When the time period specified on the label 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 article "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, but keep in mind that Delta Dust is flammable.
- I HIGHLY recommend you purchase Damascus earth (diatomaceous earth) (DE). After you spray, sprinkle some DE under mattresses and couch cushions and behind beds, dressers, and other furniture. They key is to place the DE anywhere you did not spray.
- You also need bed bug-proof mattress covers. Once you finish spraying, seal all mattresses uptight.
- The bed bug extermination checklist can help maximize the efficiency of your bed bug removal plan. There is also a price chart to help understand the cost.
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 get 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).
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 three 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-cluttering, 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, you should seal up any cracks and crevices where a bed bug nest could be hidden. This can be a little time consuming but is worth it. To learn more read the article 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.
