Pigeons are a common sight in cities around the world, and San Francisco is no exception. While some people enjoy feeding and watching urban pigeons, others find them to be noisy, messy and a nuisance. Pigeons build nests and leave droppings on buildings, sidewalks, public art and monuments, which can quickly become an unsightly and unsanitary problem. Getting rid of pigeons in San Francisco takes some work, but it can be done through a combination of humane deterrents and population control.
Why are there so many pigeons in San Francisco?
There are a few key reasons why pigeons thrive in urban areas like San Francisco:
- Abundant food sources – Pigeons are able to find plenty of food from handouts, litter, outdoor restaurant seating, and food waste.
- Ideal nesting sites – Pigeons nest on ledges, window sills, roof overhangs and holes in buildings, which provide shelter and protection.
- Limited predators – With fewer predators like falcons and hawks in cities, pigeon populations can grow unchecked.
- Urban heat island effect – Cities tend to be warmer than rural areas, creating a more favorable environment for pigeons year-round.
These factors allow pigeon flocks to thrive and multiply in urban environments. Pigeons are highly adaptable birds that have learned how to take advantage of city life. San Francisco’s dense neighborhoods provide everything pigeons need to prosper.
Problems caused by pigeons in San Francisco
While pigeons may seem harmless, a large pigeon population can cause a few different issues:
- Property damage – Pigeon droppings are acidic and can deteriorate paint, stonework and metal over time. Droppings also clog drains and air conditioning units.
- Noise – Cooing and fluttering sounds from flock activity, especially at dawn and dusk.
- Health concerns – Pigeon droppings and feathers contain allergens and fungus that can cause respiratory issues in some people. Droppings may also harbor disease organisms.
- Mess – Feathers, droppings and nesting materials collect on rooftops, windowsills, sidewalks and yards.
Accumulated pigeon droppings and feathers create unsanitary conditions in public spaces. Feces, seed casings and feathers can damage sensitive electrical equipment and machinery as well. Pigeon overpopulation needs to be controlled not just for aesthetic reasons, but for public health and safety.
Humane pigeon deterrents
Many methods exist for driving away unwanted pigeons from properties. Whenever possible, humane deterrents should be tried before considering other options:
Pigeon spiking
Installing plastic or stainless steel spikes on ledges, roofs, signs and statues prevents pigeons from landing and roosting in those spots. Spikes come in long strips or small rows. They are a passive and humane way to block pigeon access.
Netting
Netting placed over window sills, eaves, roofs and other structures keeps pigeons from nesting and perching. The netted areas can then be cleaned up and kept clean. Opt for a small mesh size of 5/8-inch or less so pigeons cannot get through.
Repellent gels
Clear, non-toxic gel repellents can be applied to ledges and surfaces. The sticky, slippery texture makes pigeons avoid treated areas. Reapply after rain or every 4-6 weeks as needed.
Ultrasonic repellers
These electronic devices emit high-frequency sound waves that deter pigeons but are inaudible to humans. Place them on affected buildings aimed at common pigeon roosting spots. Move them every few weeks so pigeons don’t become accustomed to the sounds.
Pigeon population control
When humane deterrents aren’t enough, additional steps may be needed to reduce San Francisco’s pigeon numbers. Here are some options approved for use:
Birth control
OvoControl is an EPA-registered pigeon birth control product that humanely reduces hatching of eggs. When fed to pigeons regularly, it lowers their reproductive capacity, leading to declining pigeon populations over time.
Live trapping
Pigeons can be live-captured in traps placed in problem areas, then relocated to areas at least 100 miles away so they cannot find their way back. Trapping must be done year-round to keep new pigeons from moving into the vacant territory.
Falconry
Trained hawks, falcons or owls can be brought in to patrol areas plagued by pigeons. Working with a pest management professional, these natural predators can scare away pigeons through their presence and predatory behaviors without actually killing pigeons.
San Francisco laws on pigeon control
Various city, state and federal laws protect pigeons and regulate control practices in San Francisco:
- Pigeon feeding is banned – Feeding pigeons is prohibited by city ordinance.
- Poisoning is banned – Using poisons against pigeons is unlawful.
- Shooting is prohibited – Hunting or shooting pigeons within city limits is illegal.
- Trapping regulations – Live pigeon trapping requires permits and humane protocols.
- Nest destruction – Removal of eggs or nests with eggs is restricted during breeding season.
It is critical to comply with all applicable laws pertaining to pigeon control methods, trapping, relocation, and harvesting of eggs or birds. Review regulations with any pest control companies under consideration.
Choosing a pigeon control company
A professional pest management company can survey your property, identify attractants and entry points, and implement solutions to clear out pigeons and keep them away humanely. When selecting a provider, look for the following:
- Licensed, experienced and insured
- Offers humane deterrent installations and bird exclusion
- Has expertise with city permit and legal requirements for pigeon control
- Provides customized solutions based on inspection findings
- Conducts follow-up checks and maintenance
Look for members of the National Pest Management Association who adhere to high ethical standards. Ask for references from recent pigeon jobs as well.
DIY pigeon control techniques
For minor pigeon problems, some deterrents can be self-installed:
- Block entry points with hardware cloth, boards, metal sheeting or other barriers.
- Install bird netting over small roosting areas.
- Place tactile or electric bird repellers on ledges and signs.
- Use a garden hose to spray roosting pigeons with water.
- Remove food attractants around the property.
However, more extensive issues will require professional equipment and expertise. DIY trapping and relocation should be avoided, as it usually just shifts the problem elsewhere.
Cost to get rid of pigeons in San Francisco
Since every property is different, pigeon control costs can vary. Here are some typical price ranges for San Francisco:

Inspection fee | $75 – $150 |
