Cypermethrin Is Demon, Cynoff, Cyper

Cypermethrin insecticide is the active ingredient in
Cyper WP, Demon WP, Demon EC, Cynoff EC, Cynoff WP and Cypermethrin EC 4 ounce.
All Cypermethrin wettable powder insecticides (WP)  listed are the same strength; container sizes and brand names are the only differences.   The three emulsifiable concentrates (EC) are also the same strengths and only vary in sizes offered and brand names.
Of all the Cypermethrin insecticide concentrates, Cyper WP and Demon WP 4 Pack are the most popular with do-it-yourselfers.  Use 2 scoops of Cyper WP or 2 packs of Demon WP packets for clean outs.
 "Clean-out strength" is a term used by pest professionals when mixing a solution strong enough to give an impressive initial knock-down of stubborn bugs.
German Cockroaches, carpenter bees and spiders are good examples of tough bugs.
Unless you merely want a longer residual, the regular strength (1 pack per gallon of water) is more than enough to control most ants, large roaches and provide protection against the average household pest.

One pound containers of Cyper WP, Demon WP or Cynoff WP are more economical for professionals or those responsible for controlling pests in or around larger structures, rental properties, apartments, warehouses, etc.

Liquid versions or emulsifiable concentrates (EC designation) do not normally give a super long residual (compared to WP formulations) but are still adequate for spraying monthly or every other month for general household pest control.
Use either 1/2 ounce or 1 ounce per gallon of water when mixing Cypermethrin liquid concentrates.
These liquid products provide a cheaper per gallon option.
Many apartment complexes (or other rental properties) prefer to treat on a monthly basis, simply for a better reason to see the inside of their properties.
Liquid Cypermethrin concentrates are also great for use as a drench for ant mounds, fireant mounds.

Cypermethrin is used as a crack and crevice and/or spot treatment for residual and contact control of ants, carpenter ants, cockroaches, crickets, spiders, ladybugs and other insects.  This is the most popular insecticide concentrate used in household pest control.   Available in pre-measured water soluble packets, 1 pound bulk and liquid concentrates.  CB-Air Devil is a low odor, crack and crevice aerosol which contains Cypermethrin.   CB-Air Devil cannot be shipped to NY, NJ, CT, VT, HI, AK.
Demon and Cynoff cannot be shipped to NY, NJ, CT, VT, AK
