Bed Bug Control: How to Control Bed Bugs

Bed bugs are one of the most difficult pests to control. In recent studies, scientists observed that the pests produce enzymes that neutralize pesticides. Furthermore, scientists discovered the pests acquired mutation in their nerve cells, which dulled the neurotic effect of pesticides.

The insects develop resistance to pesticides by natural selection, a non-random course of action where biological traits become shared in a population as a function of differential reproduction of their bearers. Insects that survive the pesticide are the most resistant, passing on genetic traits to their offspring.

A number of factors contribute to pest resistance one of which is the pests exposure to natural toxins for a long period of time. Another reason is that pests produce large numbers of offspring increasing the probability of random mutations. This allows the number of resistant mutants to rapidly build up. Because the insects are difficult to kill you have to use a range of techniques and treatments.

Bed bug control refers to techniques used to deter, eradicate and reduce a bed bug infestation. Five control techniques sustain knowledge building (inspection, detection, observation, post treatment evaluation and follow-up procedures) and two elimination techniques (application of treatments and prevention control measures) reduce, deter and eliminate bed bugs.

the time of action begins with acquiring knowledge about the pests. A good understanding of the bed bugs habits, biology and behaviour is the foundation of a good control programme.

People without knowledge attempt to control them and fail. The structured approach (knowledge building, prevention control and application of treatments) is the basis of effective control.

acquire knowledge

Knowledge building transcends the pests biology, behaviour and habits. It takes account of cause and effect. In other words, successful control depends on finding the answers to 6 questions:

1. Why do bed bugs go into the home? They need shelter and food.

2. When did they go into the home? The extent of the infestation determines the time the pests came into the home. An established infestation implies they have been around for a while. Low infestation implies they were recently introduced into the home.

3. What can I do to eliminate them? It is important that you study the bed bugs biology, behaviour and habits and understand and implement appropriate techniques to reduce, deter, and eradicate the pests.

4. How do bed bugs go into the home? The pests can go into the home in 3 ways:

Person – someone physically takes them home in luggage or other personal belongings.

Thing – they go into the home via used furniture, equipment, clothing or any other used item.

Forced invasion – they go into the home from a neighbouring apartment, especially in a multi-unit complicate.

5. What do bed bugs look like? You must research about the pest or ask a pest control specialized to clarify the target pest.

6. Where can I get help in case of a difficult pest? Hire a pest management specialized to eliminate the pest.


Inspection is about locating harborages. Two types of inspections, visual and canine, are used in bed bug control. Canine inspection involves the use of a trained dog to locate the harborages.

Canine inspection is quick and it is 95% guarantee the dog will be successful. Since it is only 95% guarantee, visual inspection is nevertheless necessary to locate the harborages missed by canine inspection.

Visual inspection is a physical search for harborages. It is monotonous and time-consuming, but it is the only technique that facilitates locating and treating all the harborages. Although the dog locates the harborage someone has to clean and treat it. consequently, visual inspection complements canine inspection.


Detection in bed bug control refers to finding evidence that indicates an infestation. In other words, bed bug inspection facilitates detection.

What to look for

1. Adult bed bugs & nymphs

2. Eggs, egg shells

3. Cast off skins

4. Blood stains, excrement

5. An unpleasant odour described as sickly sweet raspberries or mouldy shoes scent

6. Bite marks on the body


Bed bug monitoring tools ease the observation of the pests activity. By observing the pests activity you can determine the source and extent of an infestation.

This information enables you to select and apply a range of treatments to eliminate an infestation. Treatment depends on the structure and location of the harborage site.

Post treatment evaluation

Evaluation and follow-up procedures are secondary information gathering techniques. After each treatment it is best to estimate the effectiveness of the treatment.

The aim at the evaluation stage is to determine:

1. If you achieved the objective

2. If the strategies attained their desired effects

3. If the pests were appropriately managed

4. If control methods were satisfactory

5. If the programme needs any improvement

Follow-up procedures

Bed bug control is not easy, especially in an established infestation hence the need for later follow-up inspections, observation and treatments until the pests are completely deleted.

Bed bugs are difficult pests to control. The information gathering techniques outlined above are designed to build knowledge about the pest. The knowledge you build enables you to eliminate an infestation using prevention controls, chemical and non-chemical treatments.
