For most pest infestations such as fleas or rodents, it is simple enough to treat the problem yourself. However, if the infestation is large, or for infestations such as bed bugs and termites, it is best to call in the services of a pest control company. But, what do pest control companies do exactly, and what should you expect from a good pest control service?

What Do Pest Control Companies Do?

A pest control company will exterminate a whole host of creepy pests in your home. They will deal with rodents, beetles, termites, wasps, mosquitoes, roaches, bed bugs, termites, and fleas. A pest control company will work with you to assess the level and type of infestation and then set out a plan to eradicate the pests from your home.

An exterminator will check for sources of the pests such as garbage or sewers. A good exterminator should liaise with you and your family about the costs, procedures, and preventions as well as the health risks associated with that particular infestation.

What Should I Expect From A Pest Control Company?

There are lots of things you should expect from a good pest control company. Here is an overview of how pest control companies operate.

Licensed and Insured

Before you obtain the services of any pest management company, you should check that they have the correct licenses and insurance. Because pest control companies use poisons, pesticides, and chemical fumigants, they are required by law to have the correct certification. Ask them this question and check out their website for more details. It is also well worth checking out online reviews and make sure they have good customer service and effective treatments.



When you first contact a reputable company that offers good pest control service to tackle a pest problem like termite control, you should expect to be asked questions about your particular suspected infestation. You should expect them to ask you questions such as:

  • What type of pest do you believe the infestation to be?
  • Where have you seen the pests?

You should be offered a free consultation where a technician comes to your home. This is the time when you can point out to the exterminator which areas inside or outside of your home you think are affected.

This is the time when you can point out to the exterminator which areas inside or outside of your home you think are affected.

The pest control technician at this stage should carry out a full inspection of the interior and exterior of your home. They will be looking for pests and signs of pests such as nests and feces. They will also check for sources and contributing factors as to why you have an infestation.

At this point, the technician should discuss with you and prepare a quote and report outlining a treatment plan. If you have any questions or queries about the treatment, now is the time to ask away.

Prior to Service
A good pest control company will advise you of the steps you should take prior to them attending. Depending on the suspected infestation, this will vary. They may ask you to carry out certain steps which could be cleaning and removing certain household items. You should also be advised about pets, including birds, reptiles, and fish, as well as small animals, cats and dogs that may need to be removed from the home as they could be affected by the chemicals that will be used.


You should arrange a time for the company to arrive and expect them to be on time. If, for any reason, the exterminator is delayed you should expect a good company to inform you of any delay and, if need be, reschedule the appointment to suit you.


The professional that arrives should have a clean and neat appearance and the equipment they bring should also be well maintained.


The technician that arrives at your home should carry identification with them with the company details and a photograph. In order for a person to become an exterminator, because of the nature of the job being they are required to enter peoples’ home, they are required to have background checks. This includes a criminal background check as well as drug tests.

All pest control technicians go through training in order for them to be able to evaluate and deal with infestations effectively.


The pest control technician will carry out the treatment as prescribed in the plan laid out and discussed with you. At this time, you may need to leave your home so ensure that if you are required to do so you have made the appropriate arrangements.

Post Treatment


After the exterminator has carried out the treatment in your home, once again you should expect to have a discussion with the professional. They should cover all details, such as what they have done, the areas that have been treated, what they found, and what precautions you need to take over the following hours or days.

They should inform you when it is safe for you to return and when it is safe for children and pets to return to the home. They may outline further steps that you need to take yourself such as building work that may need to be carried out or when you next need to vacuum.

Once again, take this opportunity to speak to your pest control technician about any concerns or questions you have. It might be that, in some cases, such as carpet moths, a single treatment may or may not work completely and they may re-schedule a time for a follow-up treatment.
