A professional-use cypermethrin insecticide in four water-soluble 9.5 g packets for labeled pest-control work.
Professional structural pest control
Cyper WSP contains 40% cypermethrin and is labeled for licensed or state-registered applicators. It is offered here as four water-soluble packets of 9.5 grams each, 38 grams in total. The retail unit is the four-packet package. Its uses include structural pest work across homes and commercial accounts, subject to the specific site directions. It is a professional product even when the pest problem occurs in a residence.
What a water-soluble packet does
Each inner packet holds a measured amount of wettable powder concentrate. During the mixing process, its film dissolves in water and releases the powder into the spray mixture. The packet is therefore part of the preparation system, rather than a sachet that is cut open and sprinkled into a crack. Dry dust application is a different process. Keeping those formats distinct matters when choosing equipment and preparing for a service visit.
Mixing produces a suspension
The powder is dispersed in the water for spray application. The label describes placing the packets in the spray tank and allowing them to dissolve with agitation. Water-soluble packaging does not make the concentrate a finished spray, nor does it remove the need to distribute the powder through the carrier. The number of packets and finished volume depend on the concentration specified for the target pest and treatment.
Different structural tasks
An indoor crack-and-crevice application targets insect shelter points rather than spraying every accessible surface. Exterior treatments address listed locations around structures where pests occur or enter. The label includes ants and cockroaches, with additional directions for pests such as fleas and ticks. These tasks differ in where the spray belongs. A product with several pest names still needs an application plan suited to the actual account.
Contact and residual action
The manufacturer describes contact and residual control, meaning the treatment can affect listed pests present during application and those that later encounter treated surfaces. It also describes the formulation as odorless and non-staining. Those features can be useful around finished structures, but do not turn every indoor surface into an application site. The four-packet format gives the professional a countable supply for label-defined batches without measuring loose powder from a bulk container.
Directions for use
Mixing Procedures Each foil envelope of Cyper WSP contains water-soluble packets of Cyper wettable powder. The foil envelope must be opened for use. Because water-soluble packets readily dissolve in the presence of moisture, do not allow them to get wet before adding to the applicator tank. Wear dry gloves when handling the water-soluble packets. Handle with care because excessive handling may cause rupture of the water-soluble packet. Unused water-soluble packets should be stored in the original foil envelope, folded over to minimize exposure to moisture. Cyper WSP must be diluted with water for applications using hand-held or power- operated application equipment. For best results dilution should be achieved using the following steps. 1. Fill applicator tank 1/2 with water. 2. Add desired Cyper WSP packet(s). 3. Allow 1-2 minutes for dissolution of water-soluble packet(s). 4. Close application equipment and agitate, stir or shake applicator tank. 5. Finish filling applicator tank and agitate again before use to ensure satisfactory suspension. Note: • Shake or re-agitate application equipment before use if application is interrupted. • Mix only amount of application volume required for each use. • Do not store dilution in application equipment overnight.
