At A Glance
What is CYMEX?
Cymex is a great solution for bed bugs. Cymex is a borate-based liquid spray that kills bed bugs on contact. Cymex also controls and
prevents fleas, dust mites, carpet beetles and household fungus.
CYMEX at a Glance:

- Provides residual protection for fleas and dust mites
- No known resistance
- "Green" product -- low toxicity & highly effective
- For use in areas such as apartments, hotels, motels, offices, homes, hospitals, restaurants, schools,supermarkets, trains and warehouses
- Available in quart spray containers
How Does CYMEX Work?
The active ingredient in Cymex is a borate salt. Borate salts work by taking advantage of a unique feature in the biology of dust mites, fleas and other insects. Cymex leaves a residual on the pests' food sources. They die after ingesting borate-laced dried blood (flea larvae) or borate-laced dead skin particles/scales/dander (mite larvae/nymphs). The mode of borate action is the same as for termites or ants after ingesting a borate-treated food source.
Interestingly, this mode of action does not affect the insect’s central nervous system, so insects cannot develop resistance to Cymex. This makes Cymex the perfect choice for tough-to-control and insecticide-resistant infestations.
Cymex does work differently on bed bugs than it does on fleas and dust mites. Cymex kills bed bugs on contact. It enters through the spiracles and possibly even the bed bugs' intersegmental membranes. Bed bugs cannot ingest or absorb Cymex once dry, so there is no residual effect.
Over the years, many pesticides have been voluntarily removed from the market or phased out by the EPA due to toxicity concerns. Borate-based Cymex is one product you can count on to do the job today and be here tomorrow.
The Science Behind CYMEX
Cymex is a low-toxicity insecticide that has a low environmental impact.
The active ingredient is the natural borate salt disodium octaborate tetrahydrate (DOT). DOT is a natural form of elemental boron, which is essential for the healthy growth of plants and believed important in human calcium metabolism. Because animals and humans simply take what they need from their diet and rapidly excrete any excess via the kidneys, DOT has a low acute toxicity and is about half as toxic as sodium chloride or table salt (in a laboratory setting), but it’s very effective against insects and fungi that do not have the same excretion mechanisms. DOT maximizes the solubility, the rate of dissolution and the boric oxide content to give a borate active ingredient far superior to traditional boric acid or borax.
At the levels used in Cymex applications, it prevents pest infestation by inhibiting pest metabolism on a cellular basis. The tetrahydroxyborate anion forms a chelate complex with the cis-adjacent hydroxyl groups in the ribose sugar of nicotinamide adenine dinucleotide (NAD), with the cationic nitrogen of the nicotinamide moiety providing electrostatic stabilization of the chelate. In this configuration, NAD and NADP cannot be used by the dehydrogenase enzymes of glycolysis, the pentose phosphate pathway or the tricarboxylic acid pathway, and so the cellular energy generating mechanisms, including adenosine triphosphate production, are shut down.
