The Safety of OvoControl


We often get questions about the active ingredient in OvoControl, nicarbazin.

Although the chemical has a long history, its use as a contraceptive for pest birds is relatively new. Originally developed by Merck in 1955, nicarbazin has been used as an FDA registered anticoccidial for chickens for more than 60 years.

Coccidiosis is a very common and debilitating enteric disease which occurs during the first three weeks of a chicken’s life. Adding nicarbazin to the feed prevents the disease. A large portion of the chicken consumed both inside and outside the US is treated with the drug.

Interference with egg hatchability occured when nicarbazin was inadvertently administered to breeder chickens. The eggs from these chickens are supposed to hatch! Innolytics developed this unwanted “side-effect” in chickens into birth control for pigeons and other pest birds.

As both a food animal drug and pesticide, nicarbazin has been vetted by both FDA, EPA and a variety of other international regulatory agencies including EFSA in the EU and MAFF in Japan. The compound has been studied extensively and the environmental data package reflects the state of the art.

Nicarbazin is non-toxic and it is difficult to find much in the world of drugs or pesticides that is less toxic or more environmentally benign.

Innolytics continues to work on additional applications for this unique compound.

Automatic Feeder Assembly

Ovocontrol now has a how-to video for our automatic feeders! For OvoControl's contraceptive program to be effective, you should use an automatic feeder. This machine triggers once a day so the birds receive the necessary amount of bait. The new and improved automatic feeders are also easy to assemble and operate.

Here's a video on how to assemble an OvoControl Automatic Pigeon Feeder.

Birth Control For Birds: Will It Solve Your Pigeon Problem?

Is the avian population a problem in your area?

If it is, it’s a good bet pigeons are the culprit. In many places around the world, feral pigeons are considered pests. This  is why commercial property owners are hard-pressed to find a solution to their pigeon problem. Traditionally, people have resorted to exclusion techniques, trapping, or poisoning. These days, the answer has to be a humane and cost-effective option. In this regard, birth control is certainly an avenue that many communities and businesses find viable.

Birth control for birds — will it solve your pigeon problem?

People have been known to remove eggs and replace these with fake ones to prevent the mothers from laying more. This is a birth control option and not the most practical means for downsizing a huge pigeon population.

Another method of birth control used on pigeons to prevent their flock size from getting any bigger is egg oiling. This involves hunting down pigeon eggs and immersing them in paraffin or vegetable oil. The oil clogs up the pores and suffocates the fetus within. Understandably, there are people who disapprove of the practice and represents a very labor intensive option.

Humane pigeon control

Meanwhile, oral birth control is beginning to make its way around the globe as a practical and feasible method for solving the pigeon problem. It was developed to provide a humane option for controlling the population growth. It is mostly used on avian species, including feral pigeons and Canada geese.

When used on pigeons in their reproductive season, it effectively decreases the hatchability of their eggs. Like human contraceptives, it is fully reversible. Care has been taken, to prevent non-target species from being exposed to it. For instance, it comes in a kibble form that is very attractive to pigeons.

Of course, oral contraceptives will simply prevent the addition of new members to the population and it will take some time before their profound effect is felt. Studies done on this, however, show a 50 percent population decline, annually. In some cases, it is recommended that birth control be implemented in conjunction with exclusion techniques, such as the use of nets, spikes, and electrified strips.

So, if birth control for birds is a safe and long-term solution, then it is ideal for use in areas where a few birds can be tolerated. Some of the large-scale sites and facilities where it should be used are schools, power plants, refineries, airports, and urban areas.

Barcelona Puts Its Pigeons on the "Pill"

Nov 28, 2016 06:19 AM EST

The growing population of pigeons in many parts of the world is becoming a very nasty problem.

One of the tourist attractions in Barcelona and other parts of Europe is feeding pigeons in plazas and patios of historical landmarks. However, the birds have increasingly become a problem for the past decade as they tend to trash the city, turning it into a giant dump.

The birds have been reported to poo on not only historical landmarks and buildings but also on tourists. Local authorities have been continuously receiving complaints regarding this matter. The government believes that putting the birds on contraceptive pills may gradually solve their problems regarding waste.

According to a report from Express UK, early this year, there had been a proposal regarding the euthanization of the birds to significantly reduce their population by a huge percentage. However, the proposal received protests from various animal rights groups from all over the world. This leaves the government with a dilemma on how to reduce the bird's population.

Now, a new means of control has been put in place to replace the original plan of killing the birds. The birds will be fed contraceptive food to put contraceptive pills into the birds' system. It is expected that by mid of 2017, special feeding dispensers will be installed all over the city which contain contraceptive food.

The Barcelona government has considered expert advice to successfully perform the operation without harming the birds. Results will be analyzed after the first year to see how the new "feeding system" will affect the general health of the pigeons. It is also going to be checked whether or not such an operation will be fatal to pigeons. The operation is expected to cut down the pigeons' population by as much as 80 percent in the next five years.
