This time of the year we often get questions about the effects of OvoControl on migratory birds.
To begin, OvoControl represents a contraceptive and not a sterilant. The effects of a sterilising agent are permanent whereas a contraceptive temporary. Any undesired exposure is quickly reversible. There are several natural safeguards built into the system,
Unlike resident birds like pigeons, migratory birds migrate. If a migrating flock lands at a treatment site, they do not stay long. It takes 5-7 days to establish a contraceptive level of the active ingredient in the plasma. Therefore, a one-off dose of OvoControl has no effect. Furthermore, the excretion rate is rapid, and the contraceptive concentration in the plasma is depleted in 2 days. Bottom line, for contraception to occur, the bird must receive consistent and adequate dosing. Anything else has no effect.
OvoControl is available just once a day at the automatic feeder and is not applied ad. lib. Once the daily bait dose is consumed, there is no further opportunity to consume bait until the next day. Pigeons normally gobble up the bait at the feeder within a matter of minutes.
OvoControl does not represent a secondary risk to any raptor or scavenger.
Over the last decade, the number of reported non-target incidents has been limited to a handful. This typically occurs at facilities with competing food resources.
There is scientific support and documentation for all these claims, and we are happy to provide references.
OvoControl is a ready-to-use bait, dispensed on flat rooftops with an automatic wildlife feeder. This effective and humane technology is especially useful for managing birds in larger areas without having to resort to poisons or labor-intensive trapping programs.
