Hiring Checklist for St. Catharines
Before hiring a pest control company in St. Catharines, verify every item on this list. These steps protect your investment and ensure you are working with a qualified professional.
Confirm the company holds a current MECP Operator Licence
Confirm the technician arriving at your home holds a valid Exterminator Licence for the work being done
Verify WSIB clearance and at least $2M general liability insurance
Get a written treatment plan that identifies the pest, the products used, and the safety re-entry time
Ask whether follow-up visits are included — bed bugs and cockroaches almost always need more than one treatment
Confirm the warranty: what happens if the pest returns within the guarantee window
Red Flags to Watch For
If a pest control company in St. Catharines displays any of these warning signs, consider looking elsewhere. Protecting yourself starts with recognizing these patterns.
Cannot produce a current Operator Licence or technician Exterminator Licence number
Quotes a one-visit guarantee on bed bugs, cockroaches, or rodents
Refuses to disclose which pesticide products will be used or their MECP class
Offers a price far below market — licensed treatment carries real product, training, and insurance costs
Pressures a multi-year prevention contract before they have identified the actual pest
No physical business address or only a generic call-centre phone number
Questions to Ask Before Hiring
Are you licensed by the Ministry of the Environment?
Good answer: Yes, our company holds an MECP Operator Licence and our technicians hold Exterminator Licences. I can show you both.
What products will you use, and what class are they?
Good answer: I will identify the products and their MECP class on the treatment plan, including label-required re-entry times.
Is a follow-up visit included?
Good answer: For bed bugs, cockroaches, and rodents I include at least one follow-up because these pests rarely resolve in a single treatment.
What is your warranty if the pest comes back?
Good answer: I cover return visits within a defined warranty window in writing. The terms depend on the pest and the access I have.
