Some pesticides work effectively if the insect comes into contact with it. So you may have to wait for a week before you could do a deep clean to see desired results. Baits are used to attract the pests and ingest them so that they can be eliminated. They may look like a stain on your wall and if cleaned immediately the service will not be effective. Hence it is advisable to check with our technicians when to wipe and deep clean after service.
