Why Control Mosquitoes? Besides mosquitoes and sand-flies being a national nuisance, especially in popular tourist areas, they are also a major health concern. Sand-flies and mosquitoes are carriers of some of the world's most severe diseases and account for more human suffering than any other single pest known to man. Mosquitoes and sand-flies are often chronic nuisance pests throughout the spring and summer, and their bites may also cause allergic reactions in many people.
VectoBac is Effective VectoBac is a B.t. insecticide that effectively controls mosquito and sand-fly larvae in a safe and environmentally friendly way. It offers a sensible and effective alternative to synthetic chemicals.
VectoBac was successfully used in Napier, Gisborne and more recently Northland to control the Australian Southern Saltmarsh mosquito that carries the Ross River virus. Because of its high level of efficacy and its environmental acceptability VectoBac is rapidly gaining popularity in mosquito control programmes around New Zealand ports, airports and regional parks.
What is a B.t.? B.t. (Bacillus thuringiensis) is a naturally occurring bacterium found in most environments throughout the world. It is harmless to humans, animals, birds and fish, but lethal to many pest and disease carrying insects.
The active ingredient in VectoBac is a strain of B.t. called Bacillus thuringiensis israelensis H-14 (B.t.i), which is found in soils and aquatic environments. Since its discovery in 1978 VectoBac has been used successfully to control mosquitoes and sandflies throughout the world.
How do B.t.’s Work? B.t. products contain spores and toxic crystals, which must be eaten by the insect to be effective. VectoBac is placed in water areas where mosquitoes breed, such as storm water and drainage systems, marine and coastal areas, amenity and effluent ponds. Once the B.t. is eaten by the larvae the bacteria damages the gut causing death. There has been no known development of resistance to VectoBac. VectoBac is Fast VectoBac has a rapid effect on mosquito and sandfly larvae killing them in four to 24 hours. VectoBac is Eco-Friendly Because VectoBac is a biological larvicide it is ideally suited for public and environmentally sensitive areas. During its ten years of commercial use there has been no reports of adverse effects on the environment. VectoBac has been used throughout the world in all types of breeding sites which include freshwater and salt marshes, sewage lagoons, swamps and bog areas, creeks, streams and rivers.
VectoBac is compatible with natural predators such as mosquito fish, flatworms and other beneficial insects and no toxic effects have been demonstrated in mammals, fish, birds and other wildlife.
VectoBac is biodegradable and leaves no residues. In water it has a half life of less than 7 days and is naturally degraded by aquatic micro-organisms and sunlight.
