Pest control is described as the regulation or management of a species defined as a pest. As a resident, there are certain actions you can take to help with pest control and keeping our green spaces beautiful.
The City of Prince George has operated a Nuisance Mosquito Abatement program since 1986 to reduce mosquito annoyance for residents and visitors. The most immediate responsibility of the program is to control mosquito nuisances to a level tolerable for visitors, residents, and livestock, especially during the peak mosquito season in April, May, and June.

A list of known breeding sites has been compiled and is used for monitoring and implementing treatment activities. There are more than 350 identified treatment sites and the City continues to add to this list. Larvicide, an insecticide specifically targeted against the larval life stage of an insect, is commonly used against mosquitoes. The City treats breeding sites, both by ground and air, when larvae reach certain threshold levels.
The rate at which the snow melts can have an impact on mosquito levels, where faster melting of snow creates more pools, which can contain larvae. Residents can help by removing all standing water from their property.
The treatment of flood plains is regulated by the Department of Fisheries and Oceans. If the river level falls quickly, treatment occurs before the mosquitoes have time to develop into adult mosquitoes. If the river level falls slowly and disconnects slowly from other pools and channels, the mosquitoes will have time to fully develop into adults. Treatment is more effective after the pools and channels have disconnected from the main river channel.
Ants are an integral part of our ecosystem. They are responsible for cleaning the ground of all debris. Ants are exceptional housekeepers, turning litter and natural debris into valuable soil, rich in essential nutrients.
The City of Prince George has discovered treating an active ant hill with pesticides and/or natural controls forces the ants out of the active nest, and in turn, these ants rebuild up to 5 new nests in the same area. As a result, the City of Prince George no longer treats ant hills in greenbelts or public parks.
If your property borders on a greenbelt or natural area, do not dump your garden waste into this area. It is illegal and encourages nature's housekeepers to come to your property and your neighbour's property.
The City of Prince George is visited by tent caterpillars every year. Some years are worse than others, but while these caterpillars are unpleasant, they are a short-term nuisance in most locations.
Caterpillars complete their life cycle in seven to eight weeks. Around mid-June, they will crawl away from their natal tree and seek a protected place in plants, under leaves, or on structures to attach and spin their cocoons. Adult moths emerge from these cocoons about 7-10 days later. Tent caterpillars follow a boom-bust population cycle and the cycle varies, depending on weather and other factors.
Tent caterpillars eat the leaves of the branches of the trees they inhabit, but once they vacate the tree, the branches will usually grow new leaves. This does not affect the overall health of a healthy tree.
Spraying pesticides to kill tent caterpillars on residential City-owned boulevard trees is not permitted. If you are unsure if a tree is City property, you can call 250-561-7600 to check, ask questions, or report a problem.
