The safe Swak flying insect control aerosol (will also kill many crawling insects and particularly useful in animal housing).
MAINLY USED FOR CLUSTER FLY CONTROL IN ROOF VOIDS One can of Swak natural insecticide aerosol spray covers an area of up to 6,000 cubic feet (168 cubic metres)
Can only be used in the automatic aerosol dispensers for control of flies and other insects in roof voids (natural and safe pyrethrum ingredient insect killier that is extracted from the chrysathemum flower).
Swak insect killer/repellent provides highly effective fast-acting insect knock-down and repellency.
Each spray dispenses a small dose of Swak, creating an environment that quickly knocks-down and kills flying and crawling insects. The formulation and low dose dispensing means that it is effective in controlling insects while being reasonably safe to humans and other mammals that may be present.
We would not recommend having a unit in a bedroom unless it is turned off at night and do not use 24/7 in occupied rooms.
Wide spectrum insecticidal qualities - kills all types of flies, mosquitoes, gnats, moth, ants, wasps, fleas, spiders and other household pests.
Very low toxicity to mammals.
3,000 metered sprays per refill. On a 7.5 minute setting the can should last approx 15 days, 15 minute (30 days ) and 30min (60 days).

Use only with an automatic aerosol dispenser, available in related products...

Swak is often out of stock due to irregular supplies of natural pyrethrins. In view of this we now carry an alterntive product named Prevent Auto. This products are almost identical in terms of ingredients and spray can type. We have been supplying alternatives in place of Swak on and off for nearly two years without any customer issues. By carrying these products we are able to fully meet the demand of our customers using first class natural pyrethrin aerosols for automatic dispensers.

If you have any questions or want advice for your cluster fly infestation, please don't hesitate to call us. We're happy to help and aim to solve your problem as best we can. Phone number is at the top of the page.
