Otterburn Park, the capital of the Montérégie region located on the South Shore, is a city in full commercial expansion. It was in a clothing store in the downtown sector, near the L’Annonciation district, that our team was mandated to solve a persistent spider problem. The owner of the business had noticed for several weeks the regular appearance of paintings in the displays, the corners of the window and the storage room at the back of the store. Beyond the unsightly appearance, the visible presence of spiders harmed the image of the establishment and elicited negative comments from customers.
Initial diagnosis and species involved
Our team technicians in Otterburn Park conducted a full inspection of the business outside of business hours. Analysis of webs and captured individuals identified common house spiders and cellar spiders, two species common in commercial buildings built on slabs or with crawl spaces. The storeroom, dimly lit and cluttered with cardboard boxes, offered ideal conditions: darkness, tranquility, the presence of small insects attracted by the night lights filtered through the front windows.
We also found several failures in the joints of the delivery door at the back, as well as gaps under the wall shelves that provided safe havens for arachnids. The presence of small beetles and psocopters in the stored boxes fed the local food chain.
Professional treatment in a commercial environment
For a trade that is open to the public, the choice of methods and products is particularly important. Our commercial spider extermination protocol includes a nighttime response to prevent disruption to operations and ensure the safety of employees and customers. We systematically vacuumed all the accessible canvases, followed by an application of insecticide gel in strips along the skirting boards, behind the fixed displays and in the corners of the storeroom.
The exterior perimeter of the building has been treated externally against insect sprays on the base of the walls, window frames and door seals. Non-toxic sticky traps have been installed in the storage area and under the low shelves to ensure continuous monitoring. The owner was informed of the precautions to be taken for the 24 hours following the treatment and of good storage practices to avoid reintroduction.
Sealing and sustainable prevention
Following the treatment, our technicians sealed the main entry routes identified: the sill seal of the delivery door, the spaces around the air conditioning ducts and cracks around the windows of the storeroom. Particular care has been taken with the areas where the electrical cables are routed through the walls. This caulking work is essential to prevent the treatment from having to be repeated at short intervals.
The owner also received a prevention guide recommending that unnecessary cardboard boxes be emptied and recycled regularly, that food should not be left accessible in the storage room, and that incoming goods should be inspected before storage. These simple measures significantly reduce food sources for spiders. For advice tailored to your type of establishment, Nova Extermination offers personalized consultations.

Results Achieved and Planned Follow-up
The business was able to reopen the next morning in a sanitized environment. The owner noted an almost total absence of new canvases during the follow-up inspection carried out three weeks after the intervention. The sticky traps found during this visit confirmed a very low residual activity. Our team recommends a quarterly monitoring program to maintain this state and intervene quickly in the event of a recurrence. For owners of commercial establishments on the South Shore who want to maintain a pest-free environment year-round, a customized pest prevention plan is the most profitable long-term investment, ensuring the reputation and well-groomed image of this Otterburn Park retail business.
