This isn't about how clean your home is
A combined approach reflects the layout and extent of activity in a space, not anything about how it's kept.
What a combined program looks like
A combined program uses elements of both a thermal approach and a chemical approach across the treatment plan, for example, addressing one part of a space one way and another part differently, or using one method for the initial visit and another for follow-up. The specific mix is planned around your space, not applied as a default.
When it makes sense
This approach tends to come up when activity spans more than one area with different practical constraints, say, a bedroom well suited to a thermal approach alongside a connected space where a targeted chemical application makes more sense. Your specialist explains the reasoning for your specific plan.
Common questions
Does a combined program cost more?
Pricing is explained upfront based on the specific plan, whichever approach or combination is used.
Is combined treatment more effective?
It's simply the right fit for certain situations, not inherently stronger; just matched to a more complex layout.
Who decides if I need a combined approach?
Your specialist, based on the inspection findings and your space's layout.
