If you know someone who has had the services of a pest control company, you should go ahead and ask him or her who they would recommend. Most people will be happy to tell you which one to contact and which one to avoid. In case you don't have any referral of a good service, you will have to pick a list of potential services from your local Yellow Pages directory. Or else you can search the internet for a local pest control service.

Once you have a list of local pest control services, make a few phone calls and get a service on the line. Ask them the following questions before hiring them.

How long have they been in business?

It is a good sign of how good a company is since the bad ones cannot survive long. But this is not the only factor to judge a company though. You must realize that every company has to start somewhere.

Are they licensed and insured?

Most pest control companies are required to have a license. But there are certainly many who operate without one. Make sure the company you are going to hire is licensed. If you are in doubt, ask for proof.

Do they have any references?

If a company is providing a good service to its clients, they will likely have a couple people who they can give out for a reference. Make sure you ask for the references and check them. You would be surprised how many companies give out names of unsatisfied clients. So check the references.

Hence, before you hire a pest control company, make sure they have a good time in business, licensed and have a few references that you can contact for their quality.
