Houseflies: not just a nuisance

Houseflies are more than a nuisance to your poultry operation. They can be expensive — and dangerous. Houseflies can transmit more than 100 human and animal disease-causing organisms,1 including avian influenza2 and salmonellosis.3 What if you could help control the development of flies before they become a problem for your operation? Now you can — with Neporex.

Neporex: a novel mode of action

Neporex is an insect growth regulator (IGR) for the control of dipterous (fly) larvae. The active ingredient, cyromazine, is from the triazine group, which as a family of pesticides is one of the least toxic to wildlife.4 Neporex has a novel mode of action – it disrupts the molting process, which is essential for the fly life cycle. It interferes with the chitin metabolism of fly larvae at all 3 stages,5-7 stopping these larvae from developing, and preventing the proliferation of the fly population. Additionally, Neporex has no negative impact on beneficial insects when used according to the label.8

For best results, start Neporex early

Early treatment will result in better control – once high numbers of adult flies are seen, there also will be a large number of developing flies present in the manure as eggs, larvae and pupae. Early treatment will reduce the chance of the fly population increasing above tolerable levels and will decrease the number of applications required to bring the problem under control.
