Frequently Asked Questions

What types of pest control methods do you use?

At Donovan’s Pest Control, we use an approach called integrated pest management, or IPM. IPM includes monitoring to determine population size and action thresholds in order to determine the pest’s life cycle and behavior patterns in order to determine the best solution for removal, which may include non-chemical methods. When choosing Donovan’s Pest Control, we consider the clients thresholds for pest activity and which options will provide the best results. Some of the many possible options include host-specific pesticides, crack and crevice baits, plant oils, mechanical methods, biological methods, etc.

How long do I have to leave the premises?
This is determined by the products and methods that are used to solve your problem. We will advise according to the methods discussed.

Are there pest control methods that are safe for children and pets?
If you have children and / or pets and you are concerned about using traditional chemical sprays, you may want to consider alternative controls and removal methods. Please note that these pest control solutions tend to take more time to create an impact. Discuss your possible options with us today!

Do the chemicals you use have a bad odor?
Some have odors, and some do not. Furthermore, some folks have sensitive noses and others don’t. We can use a low-odor or no-odor product on your property, if that is your preference.

How do I choose a pest control company, and how can I be sure they will do a good job?
Here are some helpful hints to keep in mind as you look for the right company and the right pest control methods to resolve your pest problem. First, ask yourself if the company you’re thinking of using is certified by Americans Rating Corporation, and awarded the Diamond Certification. Please review our Diamond Certification.

  • Ask friends, neighbors, or coworkers for recommendations.
  • Don’t depend solely on advertising or a sales pitch to judge a company’s record. Ask for references.
  • Ask about guarantees for the specific type of work.
  • Take time to understand the company’s recommendations for control, and any potential health concerns with the treatment options. Discuss any questions you may have.

Pesticide is a word that raises red flags in our mind, and rightfully so. With decades of overuse and blind misuse, who can trust anyone on this issue? This is why we would like to explain our thoughts about the use of pesticides.

Throughout our lives, we have heard fact and fiction about pesticides and the use of pesticides, and because of the information that we have absorbed over our lifetime, we will act upon pest issues depending upon how we perceive insects, rodents, fungus, and other living organisms and chemicals in our environment. If one uses chemicals, then they should be used carefully and wisely.

There are many chemicals available to consumers of pest control. One can purchase pesticides at your local grocery store. Or one might hire a professional to apply pesticides for them. Are the chemicals safe? And how do we actually obtain the faith that the information that we are currently using to determine the safety margin is real?

First, we must understand that today, our technology has allowed us to measure tiny molecules in our environments. For example, we now can measure parts per billion and parts per trillion and so on. This type of technology has allowed the scientists to know much more about the chemicals that are found in our environment. Furthermore, regulations have forced manufacturers to perform risk assessment analysis on the chemicals that we use within the State of California. Simply put, manufacturers have been spending millions to provide the required data. This data is reviewed under contemporary legislated regulations. Because of this effort over the past forty years we have seen many chemicals removed from public use and also from the use of professionals licensed to perform pest control.

Risk Assessment Analysis has forced those that make chemicals to rethink their approach to making chemicals. Moreover, it has forced the professionals to follow strict guidelines on the use, placement, mixture strengths, area of coverage and types of pests that can be targeted and other rules when applying those chemicals within our environments. Further, some formulations of chemicals are designed so that non-targeted living organisms are not affected by the pesticide. This alone has helped us provide better methods of control for other living non-targeted organisms and for the consumer of pest control. Ask your professional about these alternatives. But don’t let us mislead anyone.

Every product that kills a living organism is toxic. If it kills, it cannot be non-toxic. It kills, but does that mean it is hazardous to humans and domestic pets? Yes, don’t fool yourself. Using chemicals should be left up to the professionals, and this is why we recommend using our company.

Toxicity and hazard are common issues; however, they are two different issues. Whenever one uses a chemical, having a professional that is trained in pest biology and pest behavior is most important. Moreover, having a professional that understands active ingredients and properties can be very beneficial to one’s environment. Remember, pest management is meant to protect your health and environment from disease and economic loss. It shouldn’t be creating a hazard for you and your family.
