Pima College is a community college located in Tucson, AZ. With nearly 10,000 students, the main campus has a challenging mix of open areas and structures.
The Pigeon Problem
Pima’s main campus in the downtown area of Tucson consists of 11 large, low-rise buildings, expansive parking and tree canopies in a park-like setting. Pigeons were widespread on campus, although not concentrated in any particular location. The pest control operator estimated the original population at approximately 200 pigeons.
Following a site survey, the installer recommended an OvoControl population management program with three automatic feeding stations. The feeders were located on three different rooftop locations, targeting the larger flock concentrations on campus. The OvoControl program was augmented by quarterly trapping.
OvoControl reduced the population from 200 pigeons to just 5 birds over a period of 24 months. Pima college remains pigeon free.
Ideally located in downtown Minneapolis, Loring Way is situated adjacent to a city park and in the vicinity of larger hotels, office buildings, parking garages and the convention center. A seven story structure, the facility includes 182 separately-owned units, each with its own private balcony.
The Problem Pigeons
Beginning with a resident flock of approximately 80 birds, the condominium is not necessarily a large hub of pigeon activity. Birds commonly constructed nests on the outdoor balcony areas and on rooftop air conditioning equipment which became clogged with pigeon feathers, nesting debris and droppings.
Property management at the Loring Condominium had already experimented with various effigies (plastic owls) and other repelling techniques without success. Instead, the condominium installed an automatic feeder to contracept the pigeons. Despite the condominium’s position in a dense urban area, the feeder did not attract additional birds or flocks.
In the twelve months since the program was implemented, bird numbers have been reduced by approximately half, from 80 to 40 pigeons through attrition. The OvoControl program will continue to reduce the number of pigeons in the resident flock at the rate of 50%, annually.
Located in Laughlin, NV, Don Laughlin’s Riverside Resort Hotel and Casino is situated on the Colorado River. The expansive hotel includes 1,400 rooms in a high rise structure. In addition to a large casino and parking facilities, the hotel offers an RV park adjacent to the hotel.
For years, pigeons were attracted by the food, quality nesting sites and shade from the intense summer heat. While not a large population of birds, loafing and nesting areas were extensive and pigeon debris represented a perennial maintenance issue, especially in the RV Park.
The OvoControl Solution
Previous attempts at exclusion and reducing the population were unproductive. Instead, the hotel installed a single OvoControl feeder on top of an outdoor restroom facility in the RV Park. Triggered daily, in the early morning hours when the pigeons are most hungry, the automatic feeder delivers the precise amount of bait
required for the population.
Within one year, there were no longer any pigeons at the Laughlin hotel and RV Park. This kind of performance is not unusual in the desert climate where summertime weather conditions are severe.
Memorial-Hermann in Northwest Houston is a 1,200 bed medical center. First constructed in the 1970s, it has been upgraded extensively and now includes a mix of more than a dozen structures, both old and new.
The Pigeon Problem
The hospital campus encompasses more than four city blocks with structures ranging from one to five stories. As in many parts of Houston, there was a high concentration of pigeons with an estimated population approaching 2,000 birds. Loafing and nesting areas were extensive and pigeon debris represented an infectious risk.
Due to the vast numbers, live trapping was not effective since the remaining birds quickly backfilled the population. Instead the installer deployed a contraceptive program supplemented by a repelling strategy in critical areas (Eagle Eye).
In the first nine months bird pressure was reduced by approximately 75%, part due to OvoControl and part due to the repelling effect of Eagle Eye. In the most recent census, an estimated 500 birds remain attached to the property. The OvoControl program will continue to reduce the number of pigeons in the resident flocks at the rate of 50%, annually.
South Carolina has a highly developed chemical manufacturing industry. Chemical plants are typically characterized by large scope and extensive facilities and structures. “All Things Nature,” a pest control service provider based in Easley, SC developed a plan to manage pigeons at one of these facilities.
The plant is relatively isolated from other commercial or residential activity. Site management had tried and failed with other techniques to control the pigeons. There were an estimated 200 pigeons at the plant loafing and nesting on different structures at the time All Things Nature started their program.
Beginning in November 2011, All Things Nature implemented an contraceptive program augmented by aggressive trapping to quickly draw down adult bird numbers. A single feeder was installed on the flat rooftop of a utility building, dispensing bait at sunrise each morning.
Within six months there were just five pigeons remaining at the site. OvoControl P (reducing reproduction) in combination with aggressive trapping (increasing mortality) were successful in rapidly reducing the bird burden.
