For Control of Red Mite & Litter Beetle

Not suitable for direct application to animals.

Mostyn Duo offers quick and long lasting control against a wide range of flying and crawling insects. A highly specialised combination of microencapsulation and emulsion-in-water technology, the active ingredients offer dual control.

When sprayed, prallethrin (EW) delivers a fast knockdown and flushing effect, while the microencapsulated cyphenothrin gives long lasting residual control. As well as being ideal for use in a variety of environments.

Mostyn Duo can also be used against ants and wasps via targeted spraying application.

What is Microencapsulation?

Microencapsulation is the technique of protecting an ingredient inside a polymer membrane. It prevents the total immediate release of actives upon application and it allows prolonged efficacy over a period of time. It also reduces odour and significantly enhances operator safety.
