Suspend Polyzone

Bayer’s Suspend Polyzone contains the signature Bayer polymer-infused formulation which delivers exceptional year-round performance and delivers proven residual control for up to 90 days outdoors. This special polymer layer enables superb protection of the active ingredient from weather, irrigation and mechanical abrasion making it a perfect instrument to help control bugs in the winter time.


Suspend Polyzone Special Features

  • Special polymer technology makes sure that the active ingredient stays where it’s applied after drying and protects it from weather, irrigation and mechanical interference

  • Remains efficacious for up to 90 days on aggressive substrates, including high alkaline surfaces such as cement

  • Polymer layer ensures more active ingredient remains available over a longer period of time

  • Longer residual means you maintain control with fewer applications

  • Better, more uniform distribution of active ingredient particles than possible with conventional SC formulations

  • Provides option to increase the interval between perimeter pest management services

  • Proven reduction in callback frequency

The Science Behind Suspend Polyzone

Suspend Polyzone works with deltamethrin crystals using a suspension based formula but with an added polymer coating. This polymer coating protects the crystals from both weathering and irrigation, which reduces the residue wash-off and ensures the active ingredient will be available to the targeted pest. It also allows active ingredient to partially embed themselves on to even the most porous of services like wood and high alkaline surfaces, like cement.


As the polymer coat erodes, it slowly exposes the deltamethrin crystals, providing a controlled release over time. This controlled release allows the active ingredients to be available to pests for a full 90 days and in a much more uniform distribution than was ever possible with SE formulation which can disperse unevenly from the applicator and can also be absorbed into the applied surface.


For winter maintenance Suspend PolyZone’s label allows for variable label rates as low as 0.01%, a low-impact and economical option. PMP field trials demonstrate that at the same rate (0.01%), PolyZone reduced call-backs compared to bifenthrin by 37% (BES trials: OE10NARBY8 & OE11NARBY1).


PolyZone is labeled to control over 40 problem pests (ants, bed bugs, spiders, ticks etc.) and can also be applied to soil, turf and ground covers adjacent to structures. The flexible labeling also allows for indoor applications that are occasionally necessary in the winter months. Suspend PolyZone’s scientific formulation contributes in reducing pesticide run-off into non-target sites, an environmentally responsible approach to perimeter pest management that customers are sure to appreciate.

Application Instructions


To apply suspend polyzone, you will need:


  1. Begin by filling approximately half of the container with water then apply the appropriate amount of Suspend Polyzone based on your container size. This information can be found on the products label.    

  2. Shake your container well then open it once more to fill the rest of the container with water. Be sure to carefully pour water into your container to avoid spills.

  3. Close your container tightly and give it one last shake to ensure even distribution.

  4. Apply Suspend Polyzone outdoors on all door frames, window frames, areas where utilities (cables, pipes, wires) enter into the structure, a band of soil 6 to 10 feet adjacent to the structure, also to a height of 2 to 3 feet on the foundation where pests may be active or may find entrance.

Is this product safe for pets?
Vickey W on Sep 22, 2018
BEST ANSWER: Yes! Let it dry first! Suspend is a lower toxicity chemical that is micro encapsulated which is a good thing.
Is this product a repellent or a non repellent?
Harvey on Nov 3, 2016
BEST ANSWER: Suspend SC Polyzone would not be considered a non repellent insecticide, but works great on controlling and preventing insects on pourous surfaces, such as concrete, stucco. Best to think about products such as Phantom, or Taurus for control of ants specifically.
Can Suspend Polyzone be used in a mistaway system?
Daniel N on Jun 8, 2018
BEST ANSWER: It would not have been tested to see if it would damage the system. Suspend Polyzone is used in a fogger to control mosquitoes.

But you will get the same results with Stryker 5-25.
