Pest control company's can be as different as the sunrise and sunset, they both look the same at the time but they are going different directions. A good company is always changing, trying different techniques, looking for ways to achieve better control over animals (insects, rodents and other small mammals) while doing it safer, being more environmentally conscious. On the other hand the not so good company is saying, if it's not broken why fix it, or if I can't get control with this pesticide I'll try another and spray more!
More for the money. If the company said they will spray your entire yard to get control of general pests, chances are they don't know where to find the pests to begin with and are using volumes of pesticides to balance their lack of pest control expertise.
If you have to give up safe pest control
practices to gain control than you are sidestepping the hole
issue, that is a "safe environment".
