Oiling eggs is a potential management method for controlling nuisance or depredating populations of ring-billed gulls, Canada geese, and other bird species.

Efficacy data were collected for white mineral oil and corn oil to reduce the hatchability of ring-billed gull eggs. Egg failure was 99% in corn oil, 96% in white mineral oil, and 35% in control eggs. Most treated eggs that hatched were treated early in the incubation period, 1 to 8 days after clutch completion.
