Saint-Laurent: one borough, many types of buildings
Industrial and commercial zone — exterminator Saint-Laurent
In warehouses, loading docks and commercial basements, humidity attracts pill bugs, silverfish, and earwigs ; a perimeter spray and better moisture control keep them away.
Residential Buildings and Warehouses — Pests Saint-Laurent
In the duplexes and triplexes on the borough’s older streets, mice get in through worn mortar, weep holes and pipe openings. We seal these gaps during the treatment.
