Infestation by pests within your own four walls is always inconvenient. In most cases, homeowners instinctively follow the urge to eliminate this infestation immediately. There are many reasons for this. Be it for fear or disgust to prevent the spread of pests or for hygiene concerns.

And the latter are justified: Insects and pest rodents bring bacteria and pathogens with them, which makes pest control a necessity.

DIY Pest Control?

The Internet, the richest knowledge library in the world, is not stingy with tips, tricks and tutorials that encourage homeowners to do their own “quick and easy pest control”. But despite all their zeal, there are risks that are often not even considered or misjudged:

  1. Is the use of certain chemicals harmful to my health?
  2. Or that of my relatives/roommates?
  3. What influence do pesticides or biocides have on the environment?
  4. Are they harmful to my pets?
  5. And what if children come into contact with toxins?

Pest control is not as easy as it seems at first glance.

A professional pest controller, or pest controller, as the vernacular usually calls the trained experts, is of course associated with costs, which motivates some homeowners to carry out the pest control themselves.

But we, as pest experts, often learn in customer contact about medium or severe consequential damage, which on the one hand has been caused by improper pest control measures and which, which is much more regrettable, could have been avoided by a professional!

Companies such as Rentokil are subject to strict statutory regulations and, through highly specialised training programmes for their employees, ensure that there is no damage to health or the environment.

Health Risks

Effective pest control, which not only eliminates pests but also prevents new pests from settling here immediately, almost always requires the use of chemicals. However, the effects and consequences that these chemicals can have are often underestimated.

An example – you discover an actively inhabited wasp nest on your terrace. The nearest DIY store is not far away and it may be obvious to want to become master of the situation yourself with wasp spray. Rarely, however, is one questioned:

  1. Which active substances are actually contained in the chemicals?
  2. Can children or allergy sufferers come into contact with them?
  3. Does the fog cloud or aerosol cloud that develops when the chemicals are used move to a busy neighboring property?
  4. Can you get close enough to the active wasp nest so that the chemicals can act at all?

Wasps that feel threatened swarm out and attack anything they think is a threat in the vicinity of the nest. An unsuccessful attempt at control means not only a health risk for you, but also for relatives or neighbours. Careful and cautious use is recommended, especially with pesticides.

Environmental Risks

Did you know that bees or bumble bees are protected according to the Federal Species Protection Ordinance (BArtSchV)? Honey bees are regarded as beneficial insects. They react sensitively to interventions in their habitat and environment. Professional pest controllers are specially trained to relocate bee nests in the event of danger, without damaging them if your nesting site is a danger.

DIY insect killers, on the other hand, are potentially capable of contaminating soil and air if not used properly. Improper spraying of bee nests with pesticides, to stick to our example, can cause the chemical toxins to enter your home or come into contact with vegetables in the garden or water supplies.

Economic Risks

Despite all advice and tricks we recommend from experience: only a professional pest control removes the pest infestation long term, efficiently and cost-effectively.

What Does This Mean for You?

Weigh up the risk: The costs you incur for your own use of pesticides and additives can often exceed the costs for a professional and highly effective professional treatment. Not to mention the follow-up costs of unsuccessful control methods.

Companies in particular are required to call on the professional help of a pest expert in the interests of their employees and customers, but also of their goods or their good reputation. The self-use of pesticides is not least subject to certain requirements of the Ordinance on Hazardous Substances (GefStoffV, Annex I, No. . 3). Therefore, do not take any risks and contact a trained pest expert directly. He knows potential risk areas in the commercial environment, as well as suitable measures to eliminate pest infestation and prevent it with active measures.


Always weigh the risks of pest infestation against the method of treatment. In case of doubt, it is worthwhile to consult a professional pest controller for health, ecological and often not least economic reasons.

This is how professional pest controllers help you:

  1. You know the shelters and hiding places of pests.
  2. They effectively eliminate infestation
  3. If possible, they prevent a renewed infestation by active measures
  4. You work professionally in the interests of people and the environment.
