Invasive Pigs

Invasive pigs (Sus scrofa) can be Eurasian boars, domestic pigs, and hybrids that escaped, have been released, or were born in the wild. Also known as feral swine, feral hogs, wild hogs, wild pigs, and wild boar.

DID YOU KNOW?

African swine fever (ASF) is a contagious viral disease that only affects pigs. ASF poses a serious risk to Canada’s swine industry and economy if introduced. ASF is currently NOT in Canada. Let’s keep it that way by staying vigilant, practicing biosecurity, and reporting any symptoms immediately to your veterinarian.

*For more information on pigs and ASF check the B.C. Small Lot Pork Producer Management & Production Manual

WHERE ARE THEY NOW?



If one of your pigs escapes, follow these steps:

* If human safety is at risk, call 1-877-952-RAPP (7277) or 911 for emergencies

PIGS ARE NOCTURNAL

Even if you do not see pigs they could still be around your property! One of the best tools for Early Detection and Rapid Response (EDRR) of invasive pigs is setting up camera monitoring networks.

NOTE: Anything edible or compostable can be an attractant, including manure. Pigs are a major invasive pig attractant, because of the associated feed and for mating. Invasive pigs can tear down or jump over fences to breed. Secure your pigs properly!

Report Invasives

After reporting an invasive pig sighting, authorities assess the report, investigate the area, and implement measures like trapping or removal if needed. They may also raise public awareness and use the data to track and manage invasive pig populations, helping to prevent further spread and damage.

 

 

 

 

Invasive pigs are extremely smart and hunting can cause them to disperse and move into new areas, potentially expanding their territory. Besides avoiding areas with hunting activity, they also become more nocturnal or hide in inaccessible terrain putting pressure on other native species.

Effective control typically requires a combination of strategies, such as reporting, trapping, targeted removal, habitat management, and public education, alongside strict biosecurity measures to prevent further spread.

Invasive pigs in B.C. originated from escaped or intentionally released domestic pigs and imported wild boar, which then resulted in hybrids. These adaptable animals spread quickly, damaging ecosystems, threatening native species, and impacting agriculture. Efforts are ongoing across Canada to monitor and control their population.

Invasive pigs prefer habitats close to fresh water and can be found in forests, agricultural areas, shrublands and marshy swamplands. While B.C. does not yet have established populations of invasive pigs, their presence poses ecological and agricultural risks. Monitoring and reporting sightings are crucial to prevent their establishment and mitigate potential impacts. If you spot an invasive pig in B.C., it’s important to report them.

Report your sightings through our website or through mobile apps such as Report Invasives or iNaturalist. When reporting include as much information as possible including, location, physical characteristics, population size, and pictures (if able to take from a safe distance).

*For emergencies please dial 911 or 1-877-952-RAPP (7277).

Invasive pigs can harm humans and pets through aggressive attacks, especially when threatened or protecting their young. They also spread diseases like ASF, or contaminate water sources which can affect both humans and pets. Additionally, their environmental damage can create indirect hazards. To stay safe, avoid approaching them, keep pets leashed, and report sightings.
