How long does it take for the effect of OvoControl to wear off?
OvoControl must be consumed for several days to achieve blood levels that affect the hatchability of eggs that are forming. Nicarbazin is undetectable in the plasma of Canada geese, mallards, and chickens 4-6 days after consumption of the OvoControl bait has stopped. The levels of DNC in the blood are reduced by half within one day after bait consumption stops. When do you start and stop using OvoControl? Depending on the site, OvoControl baiting should begin 14 to 21 days before the onset of nesting or a minimum of 7 days prior to the laying of the first egg. For example, in Maryland, the first eggs are typically laid beginning March 1. In this case, acclimation would begin during the third week of February. The recommended program for OvoControl is an eight to ten week (56 – 70 days) treatment following acclimation. How does the goose breeding season compare to other waterfowl species? Canada geese typically nest earlier in the year than most other waterfowl species. OvoControl will
