Bed bugs – detect and combat them

Bed bugs are small, wingless insects that suck blood and feed on human blood. They are nocturnal and hide during the day in small crevices and cracks in mattresses, furniture and walls.

Basically, it should be emphasized that bed bugs have nothing to do with poor hygiene and can appear even in the cleanest households through no fault of your own.

Overall, it is crucial to act quickly to prevent bed bugs from spreading further and to seek professional help if the infestation situation is more severe.

How do I recognize a bed bug infestation?

Bed bugs are annoying little parasites that can nest in our beds and furniture. A bed bug infestation can quickly become a serious problem as they multiply quickly and leave unpleasant bites. It is therefore important to know how to recognize a bed bug infestation so that you can react quickly and take measures to get rid of these uninvited guests.

Traces of blood on the bed linen

Blood stains on bed linen can be caused by various reasons. The most common cause is an injury or open wound that transfers blood to the bed. This can happen while sleeping if a wound opens unnoticed or while changing if you accidentally hurt yourself.

The color of blood stains on bed linen varies depending on how fresh or old the blood is. Fresh blood is usually bright red, while older blood takes on a darker, reddish-brown color. However, the intensity of the color can also depend on the amount of blood. It may also resemble more black dots.

Traces of blood can often be found in different places on the bedding, depending on the position of the body while sleeping or bleeding. Traces of blood are often found on the pillow when you sleep with an open wound on your face. But there can also be traces of blood on other areas of the bed linen, such as the sheets or duvet covers.

To best remove traces of blood, it is recommended to act immediately. First, you should use cold water to flush out the blood, as warm water causes the blood clot to set. You can then use stain removers or laundry detergent with bleach to treat the blood stains. It is important to follow the instructions on the cleaning products and then rinse the bedding thoroughly.

Overall, it is important to remove traces of blood from bed linen quickly and effectively while taking appropriate precautions to prevent the spread of infection.

Sweet smell in the room

There are various ways to eliminate the sweet smell in the room. First, the cause of the smell should be determined. For example, if the smell is due to damp or dirty areas in the room, these should be cleaned and dried to prevent bacterial growth and associated odors.

If the sweet smell is due to bedbugs, it is important to destroy the bedbugs immediately to prevent another infestation. Bedbugs can multiply quickly and are difficult to eradicate, so appropriate measures should be taken.

Traces of feces in the typical places

Traces of feces in the typical places are a clear sign of a bed bug infestation. When looking for bed bugs, it is therefore important to pay close attention to these traces of feces. These tracks are usually black or dark brown and have a grainy consistency. They can appear in various places that are considered typical hiding places for bed bugs.

One of the most common places where traces of poop can be found is the mattress. Bed bugs prefer to live and nest in the seams and folds of the mattress. Here they leave traces of their droppings, which are often visible as small black spots. Traces of feces can also appear on other textiles, such as duvet covers, pillowcases and bed sheets.

Another place where traces of feces can be found are cracks and crevices in furniture, baseboards and masonry. Bed bugs like to hide in these narrow spaces and leave their droppings there. Traces of feces can also often be found on the floor or carpets near beds and sleeping places.

In addition, traces of feces can also appear in other places in the bedroom and apartment, such as on curtains, in drawers, behind pictures or in cable openings. If traces of feces are found in these typical areas, it is important to take quick action to combat bed bugs, as continued infestation can lead to health problems and an increasing infestation. No matter where the traces of feces are discovered, they should not be ignored but should be acted upon immediately to ensure rapid and effective bed bug control.

Bed bug eggs

Bed bug eggs are tiny oval structures laid by female bed bugs. They are about 1mm in length, making them barely visible to the naked eye. The color of the eggs varies between a pale white and a translucent ivory. These colors help the eggs camouflage better in the environments in which they are laid.

Bed bug eggs are usually placed by females in hard-to-reach places to protect them from predators or removal by humans. Popular storage locations are therefore small gaps or cracks in mattresses, bed frames, wallpaper, furniture and even behind pictures or electronic devices. The females lay around 1 to 5 eggs per day, which means that in the event of an infestation there can quickly be a large number of eggs.

It is important to identify and eliminate bed bug eggs to prevent reproduction and further infestation. To identify the eggs, a flashlight or magnifying glass can be used to inspect the potential infestation area. If tiny white or translucent eggs are discovered in the mentioned hiding places, this is a sign of an infestation.

Overall, bed bug eggs are small, almost invisible oval structures that are usually laid in hard-to-reach places to increase their chances of survival. Quickly identifying and removing these eggs is crucial to effectively controlling a bed bug population.

Symptoms in humans

Bed bug bites are often an unpleasant and annoying problem that can affect humans. There are certain symptoms that may indicate an infestation. The bites usually manifest as red, itchy spots on the skin.

Bed bug bites often appear as small, raised bumps or wheals that may be arranged in groups or rows. The bite sites are usually accompanied by severe itching and can become infected or even lead to skin infections if scratched. It is important to note that not every person reacts the same way to bed bug bites. Some people may develop an allergic reaction to the bites, causing severe swelling and itching.

Other signs of an infestation may include small, brown spots on sheets or mattresses caused by feces or blood stains. Sometimes bed bug molt remains are found near where they sleep. If several people in a room or bed are affected by the same symptoms, this can also be an indication of a bed bug infestation.

Overall, bed bug bites can cause various symptoms on the human body, ranging from red bumps and itching to allergic reactions. An anaphylactic reaction as an illness can also occur. If an infestation is suspected, it is advisable to seek professional help to combat the problem.

How can you fight the animals?

There are several methods to control bed bugs or prevent them from causing problems. It is certainly possible to combat it on your own. It is important to consider the needs and characteristics of bed bugs in order to take appropriate measures. By knowing natural defense mechanisms and understanding animal behavior, one can successfully minimize unwanted animal visits. However, if all else fails, there is no alternative to professional pest controllers. Complete elimination and detection of bed bugs is particularly important.

Physical control methods

One method is the use of diatomaceous earth. Diatomaceous earth is a natural powder made from fossilized diatoms. It is scattered around the bedbugs' sleeping areas and works through its fine particles, which penetrate the bugs' outer protective covering and thus dry them out. It is important that the diatomaceous earth is renewed regularly to ensure effective control.

Another method is the use of collection vessels. Special containers are placed under the edges of the bed or in other hiding places for the bugs. These jars are coated with a thin film of glue or barrier fluid that prevents the bugs from climbing out and causing further damage. Collection containers should be emptied and cleaned regularly to maintain control effectiveness.

A particularly effective physical control method is thermal control. Heat and vacuum cleaners can be used. Heat - and therefore a critical temperature - is generated, for example, by using steam cleaners or hot air devices. The heat kills the bugs and their eggs. A product that can be particularly highlighted is the Hyla EST. The Hyla EST is a multifunctional vacuum cleaner that can also be used for thermal disinfestation of beds. By combining heat and high suction power, the Hyla EST not only fights the bedbugs, but also thoroughly cleans the mattresses and frees them of allergens and other dirt particles.

In summary, both diatomaceous earth, collection containers, thermal control using heat at a critical temperature and vacuum cleaners are effective physical control methods for bedbug control. The Hyla EST is a particularly versatile and effective product. Textiles should also be washed in the washing machine at temperatures above 50 degrees, if possible.


Insecticides are commonly used to control bed bugs and offer both risks and benefits.

A possible benefit of using insecticides is their effectiveness at killing bed bugs. They can quickly and efficiently reduce the bedbug population and thus help eliminate the problem quickly. They can also help contain the infestation and prevent the parasites from spreading further.

However, there are also risks associated with using insecticides to combat bed bugs. A common risk is environmental pollution and possible harm to animals and plants. Insecticides can also be potentially toxic to humans, especially if used improperly or in large quantities. It is therefore important to follow the instructions carefully and take protective measures to minimize possible risks.

The most commonly used insecticides to control bed bugs are pyrethroids such as permethrin and cypermethrin. These insecticides have strong bed bug killing properties and are therefore often used in sprays, powders or aerosols. Application amounts vary depending on the formulation and manufacturer, so it is important to read the instructions on the product carefully and act accordingly.

Overall, insecticides for controlling bed bugs offer both benefits and risks. It is important to understand the potential dangers and ensure application is done properly to ensure effective and safe bedbug control.
