Frequently Asked Questions
What makes us different from traditional pest control?
Most pest control focuses on spraying first. We focus on sealing the structure first, which stops pests from entering and makes extermination effective and final.
Why is sealing more important than spraying?
Spraying does not close the entry points pests use. Without sealing, pests simply return through the same openings.
Is this service only for condos and apartments?
No. While we specialize in condos and apartments, our sealing process is equally effective for homes, basements, and rental properties.
Does this work for mice and rats?
Yes. Structural sealing is one of the most effective ways to prevent rodents from entering a building.
Will pests come back after the service?
Once entry points are properly sealed, pests cannot return through the same areas, making repeat infestations unlikely.
Do you still exterminate pests?
Yes. After sealing is complete, we eliminate any pests already inside using targeted, professional methods.
How long does the process take?
Most properties can be inspected, sealed, and treated within a single visit, depending on the size and condition of the space.
Is this a one time service or ongoing treatment?
In most cases, this is a one time service because the structure is secured against re entry.
Stop dealing with repeat infestations. Speak directly with a technician and fix the problem the right way.
