In New Zealand, fipronil was used in trials to control wasps (Vespula spp.), which are a threat to indigenous biodiversity.[5] It is now being used by the Department of Conservation to attempt local eradication of wasps,[10][11][12] and is being recommended for control of the invasive Argentine ant.[13] In Iran it's used in different forms including a gel formed roach bait named Bersuda[14] which is popular due to minimal footprint, granularity and stickiness that is claimed to spread the contamination by infected roach to other members of the nest.[15] It is reportedly used for Integrated Pest Management.[15][need quotation to verify]
