Cypermethrin Liquid Concentrates
Liquid concentrates and wettable powder concentrates each have certain properties that make them useful tools in pest management. There are specific situations that require the use of Cypermethrin in a liquid concentrated form, instead of wettable powders.
Wettable powder concentrates are popular with pest control service companies for three major reasons: long residual, better initial knockdown of pests and more bug killing power left on sprayed surfaces. (On a porous surface, one third of EC products are not absorbed; 100% of wettable powder solution usually not absorbed.)
Some of a wettable powder's good properties can actually work against the
pest control technician. The main concern (when using Cypermethrin in wettable
powder formulations) is the visible residue left behind after the bug spray
Wettable powder residue can be removed simply by cleaning the sprayed area with a damp rag. To avoid problems with this residue, use an emulsifiable concentrate formulation. You can still have the benefits of Cypermethrin without the headache of a dissatisfied customer. An emulsifiable concentrate (usually designated by "EC" in the pesticide insecticide name) usually dries to an invisible finish.
In today's society, knowing that an insecticide has been sprayed in a
certain room or area can often cause undue panic, complaints, etc. There
are many who believe that all pesticides are evil and that there is no safe way
to control or kill bugs, spiders or other pests when using a pesticide in any
form. Spraying with a wettable powder solution indoors often results in an
unhappy customer because they see the dried product on dark surfaces.
There are other choices other than using products that leave a visible
residue. Liquid concentrates (emulsifiable concentrates, microencapsulated
concentrates, suspension concentrates) leave very little or no visible

Summary of Cypermethrin Liquid Concentrates
When spraying indoors where dark baseboards or flooring are present, use Demon
Max or Cynoff EC instead of Demon
WP or Cynoff WP. This will give you the bug killing power of Cypermethrin
without leaving an unsightly visible residue.
