Wasps are among the most aggressive and potentially dangerous pest threats Calgary homeowners and businesses face during the warmer months of the year. Unlike bees, wasps can sting repeatedly without losing their stinger, and a disturbed nest can trigger a rapid and painful mass attack that poses a serious health risk, particularly to individuals with allergies to wasp venom, for whom a single sting can trigger a life-threatening anaphylactic reaction.
At Preventive Pest Control, our professional Calgary wasp control and nest removal services are designed to safely and effectively eliminate wasp nests and populations from your property with the speed and thoroughness the situation demands. Our experienced Calgary wasp exterminators locate all active nests on your property, including those hidden in wall cavities, roof spaces, and underground and apply targeted treatments that eliminate the colony completely. Contact Preventive Pest Control today to schedule your Calgary wasp control service and take back your Calgary outdoor spaces safely.
When you find a wasp nest on your property, attempting a do-it-yourself removal can be extremely dangerous. Wasps are territorial and will aggressively defend their nest, often swarming and stinging intruders multiple times. This is especially risky for anyone with an allergy to their venom.
Hiring a trained professional with the right protective gear and effective products is the safest and most reliable way to handle a wasp infestation and protect everyone on your property.
When a wasp nest is discovered on your Calgary property, the temptation to handle it independently with a store-bought spray can be difficult to resist. However, attempting DIY wasp nest removal is one of the most dangerous pest control decisions a Calgary homeowner can make. Disturbing a wasp nest without the proper equipment, protective gear, and treatment knowledge can trigger an immediate and aggressive defensive response from hundreds of wasps simultaneously, a situation that can result in serious injury and in some cases a life-threatening medical emergency for individuals with wasp venom allergies.
Professional wasp removal from Preventive Pest Control eliminates these risks entirely. Our experienced Calgary wasp exterminators are fully equipped with the protective gear, professional grade treatments, and specialized knowledge needed to safely neutralize and remove wasp nests of any size and location, including those hidden in wall cavities, roof spaces, underground burrows, and other hard to reach areas that make safe DIY removal virtually impossible. Protecting your family and property from the serious risks associated with wasp activity is always best left in professional hands.
Thorough Inspection and Species Identification: Our experienced Calgary technicians conduct a detailed property inspection to locate all active nests and accurately identify the specific stinging insect species present, whether paper wasps, yellow jackets, or hornets, ensuring the safest and most targeted treatment approach is applied.
Safe and Effective Treatment: Using professional grade products and specialized equipment, we treat the nest and surrounding area thoroughly, eliminating the entire colony quickly while minimizing the risk of agitation and aggressive wasp behavior throughout the process.

Prevention Recommendations: Following removal, our Calgary technicians provide personalized advice on making your property less appealing to returning wasps, including guidance on sealing entry points and eliminating the food sources and conditions that attract stinging insects to Calgary properties.
At Preventive Pest Control, our goal is to resolve your wasp problem completely and restore the safety and comfort of your Calgary home and outdoor spaces as quickly as possible.
Professional wasp control is one of the most important pest management investments Calgary homeowners and businesses can make during the warmer months of the year. Wasp colonies grow rapidly throughout the summer season, with a single nest capable of housing thousands of highly aggressive insects by late summer, making early professional intervention significantly safer and more straightforward than attempting to address a fully established colony later in the season.
Beyond the immediate physical danger of wasp stings, untreated wasp nests located within wall cavities, roof spaces, and structural voids can cause secondary damage to your Calgary property as colonies expand and chew through building materials to enlarge their nesting space. Wasps are also highly territorial and will aggressively defend their nest against any perceived threat, making routine outdoor activities such as gardening, mowing, and entertaining genuinely dangerous when an active nest is nearby.
Professional wasp control from Preventive Pest Control removes these risks completely, protecting your Calgary family, guests, and pets from the very real dangers that an unmanaged wasp population poses throughout the season.

Pest Control Services
The most effective time for extermination is in the early morning or late evening when wasps are less active and most of the colony is inside the nest. While we can treat nests at any time, evening applications ensure the entire population is targeted simultaneously for a faster knockdown.
DIY removal is generally discouraged, especially if the nest is large or located in a hard-to-reach area like an attic or wall void. Professional exterminators have the protective gear and specialized aerosols necessary to neutralize the colony safely without risking multiple painful stings or property damage.
Our professional-grade treatments typically take effect within 24 to 48 hours. You will notice an immediate decrease in activity, though it may take a short period for foraging wasps returning to the nest to come into contact with the treatment and be eliminated.
Wasps rarely reuse an old nest. However, if the environmental conditions—such as a protected eave or a specific wall cavity—are ideal, new queens may attempt to build nearby the following year. Our Quarterly Pest Package includes preventative barriers to discourage new nests from forming
Yes. We prioritize the safety of your household by using targeted application methods. We treat the nest directly and apply residual barriers in areas inaccessible to children and pets, ensuring the pests are gone while your loved ones remain protected.
