I looked at the website but couldn't find the actual chemical involved.
That would make a difference to the hazard to you and the residual life of the chemical, and how fast it degrades etc.
The withholding period for chemicals sprayed on produce is the time between spraying and being permitted to harvest.
The re entry period is the time between spraying a chemical and workers returning to the site
As the Mosquito spray is technically not sprayed on produce, but used in a human environment it should have some of these values, an indication of the hazard.
That could give you some idea about when you could harvest from adjacent plants safely.
Also is there a 'mosquito season' in your area or is it 365 days a year ?
You could consider barrier plantings like sugar cane, bamboo, Sorghum along the boundary.
