If I notice some pest activity (e.g. rats, cockroaches, mosquitoes, insects), what should I do?

It is advisable to alert the people who are responsible for managing these pests to have them eliminated quickly and safely, without harming the environment. If you are responsible for this role and need professional help, we suggest that you contact a reliable pest management company immediately.

Do I have to leave my home when it’s being treated?

It depends on the treatment. If the pest control professionals need to enter your home, it is advisable to stay home to prevent possible misunderstanding (such as lost items) and monitor the work.

Do I need to treat my property monthly?

In most cases, pest control work is usually only needed once.

However, if the problem is complicated, you may need the professional to visit again to treat the issue.

Speak to a local pest control company

How can I prevent a pest problem?

It depends on what kind of pest infestation you are having.

In general, you must ensure:

  • Proper sanitation/housekeeping.
  • Correct defective engineering/architectural design to prevent pest entry and harbourage.
  • Treatment by licensed and NSRS certified pest management professionals.

You can check out our guide on termite control in our blog.

Is there a connection between pests and asthma in children?

Yes, bed bugs and cockroaches are known to trigger allergies and even lead to developing asthma in children. Their saliva, droppings and decomposing bodies contain allergens which trigger allergies and worsen asthma attacks.

What should I look out for in a competent and reliable pest control company?

We cover a checklist of traits a good pest control company has. As a guide, here are some pointers:

  1. Test the Company as to whether they are prepared to quote to you over the phone. If they are prepared to quote, they are doing it without many vital information that are necessary to do a proper job at the proper pricing. You should rule this Company out for obvious reasons.
  2. Check what type of chemicals the Company uses. If they answer that all their chemicals are approved and registered by NEA, they can be classified as safe. How they use it comes into play ie, do they follow the label instructions, do they have proper measuring utensils, do they use proper personal safety gear when handling chemicals etc.

Company background

The simplest guide is to find out how long the company has been in operation. Next, the number of staff in their company is a good indicator of the scale of work they do.

You can check how skilled are their field staff, such as asking the types of training they had gone through and number of years of experience.

Experienced Pest Knowledge

Having extensive pest knowledge is definitely a good guide to how competent the company is. Check the track record of the company, such as asking:

  • Type of work they’ve done before
  • Type of pests they have dealt with
  • Complexity of past projects they have handled previously

Technical Certifications

It is important to make sure the pest control service you have hired is carried out by our local National Environment Agency (NEA) certified pest management professionals whom have gone through the technical training program.

Ask for certifications and license if necessary.

Solving Root Source of Infestation

Besides providing the solution to control pests, professionals should be able to identify the root source of infestation such as an ant’s nest, mosquito breeding grounds, rat burrows and bed bugs nesting deep in furniture.

A pest control professional take into account both internal and external environment to determine the root source of infestation. They usually educate their customers key risk areas and actions to prevent future pest infestations.

Innovations & Technologies

A competent pest control company should offer better treatments and control methods to ensure that you get the best. Innovations with new technology and staying updated with the latest solutions should be seen highly encouraged in the business environment.

Post termite treatment monitoring

A committed specialist cares for the safety and wellbeing of their customers on a long-term basis. A credible pest control professional constantly communicates, educates and recommends useful tips and practices, not just the pest they are treating, but conducting overall home check for safety and assurance. Post termite treatment requires yearly inspection of the premises to ensure colony management is in order and there is no presence of unidentified pest activity.

How quickly can the pest control companies respond to job requests?

You can check out pest control professionals who operate 24/7. If schedule allows, pest control companies can usually be there within the hour, if not certainly in the same day.

Get quotes from pest control pros

Are there any alternatives if spraying is not allowed?

Should you face any problems to the current pest control method (such as small children & pets and spraying is not an option), you can talk to your pest control professional for alternative ways of killing the pests.

An example is using gel baits and bait stations for both cockroaches and ants, which will not be harmful to human and other animals.

Pest control safety and hazard precaution standards

When dealing with a pest control company, it is important to monitor the health and safety issue which may pose a threat to your family’s health, especially for the young and the elderly.

It is important that the pest control company is NEA approved and uses only NEA approved chemical to deal with the pests.

Check key information such as reduced risks status with the pest control professional to fully understand the process behind pest control.
