Bedbug Checklist



Bedbug Control and Management


Online shop for bedbug control




About 5-8 mm long, flattened oval, reddish-brown. Nymphs develop out of an egg into an adult in 5 stages. They are similar to the adults in form but more yellowish brown in color. After feeding by hematophagy (bloodsucking), the insects are noticeably thickened and colored from dark red to black. During the day, they hide in places such as cracks and crevices in floors, mattresses, behind electrical cables and tubing and pictures; adult insects tolerate cold and survive for weeks without feeding. Predominantly bedrooms are affected.




Bedbugs travel, sometimes from remote hiding places, to feed on sleeping humans or other warm-blooded animals (pets). The adult insects and nymphs prefer to feed in the dark. They suck blood for about 5-10 minutes. The saliva the bedbug injects is toxic and in most people causes a welt or a wheal, often accompanied by very intense itching, which can appear up to 7 days after being bitten. It can also lead to extensive inflammation of the skin, a feeling of discomfort, and impair the ability to see. In cases of high infestation, their sickeningly sweet smell in the room can be an annoyance.



Checklist / hints for bedbug control and management


Do not take articles out of the infested rooms after a bedbug infestation has been established >> danger of spreading!!!


Wash all articles of clothing that may have bugs about 30 minutes at 60°C, or use a laundry dryer about 30 minutes at 40°-45°C.


Bugs infesting sensitive articles can be thoroughly killed in a freezer for 10 hours at -17°C.


We do not treat articles of clothing (e.g. virgin wool, silk, sensitive fabrics) and electronic equipment (e.g. TV, radio, alarm clocks and so on). They can be stored in plastic bags (bedbugs die of hunger within 6 months).


Electronic equipment can be fumigated with insect-strips in plastic bags for several weeks. Due to the high gas pressure emanating from the strips, the insecticide gases permeate deeply into the equipment.


Clear the complete infested area in order to reach all hiding places and crevices. Consider disassembling the bed frame if possible and remove the mattress (think about buying a new mattress in case you have an older one).


Now thoroughly vacuum the bed frame and mattress (especially the seams).


Do not forget the cracks and crevices along the baseboards and all possible hiding places close to the bed and floor. Immediately after vacuuming, remove the vacuum cleaner dust bag, seal it in a plastic bag, and remove it from your apartment/home. You can also use a steam cleaner. The advantage here is that the steam also kills bedbug eggs.


Take apart electrical sockets or outlets (after turning off the electricity).


Remove pictures and wall-decorations from the walls and check them for small, dark reddish spots (bedbug excrement).


Prior to beginning, move wardrobes and beds away from the walls in order to easily reach all areas.


After the pest control expert has finished, remember his advice to thoroughly clean and air the area.


Just to be safe, move the bed away from the wall and wrap the bed legs with double-sided adhesive tape.




Here are a few tips on how to detect bedbug infestation before staying in a hotel.


If everyone were to follow these instructions, much would be done to hinder the spread of bedbugs.


>          The first thing to do is to check various internet sites for test reports.

>          When entering the hotel room, hang your clothes on a rod far away from the bed in order to limit contact as much as possible.

>          Clothes can also be stored in sealable plastic bags; they are usually available free of charge in hotels (as laundry bags)

>          Luggage should also be placed as far away as possible from the bed.

>          To be particularly safe, wear disposable gloves to avoid unnecessary contact with the bedbugs, which are more often than not gorged with the blood of previous hotel guests.

>          Check our website or other pest control websites to see how bedbugs appear at different stages of development.

>          Also keep an eye out for traces of excrements spots, eggs, or discarded outer-shells the bedbugs leave behind everywhere.

>          The place to start is with the mattress.

>          Remove the sheets and check for bedbugs and excrement by running a finger along the upper and lower seams.

>          Bedbug excrement consists mainly of coagulated blood; the spots are dark red to black, usually circular, with a diameter of 1mm.


These spots appear darker, almost black, on clothes and on wood. On smooth, non-porous surfaces, the spots tend to be a dark red. They can be dissolved and easily wiped away with a little bit of water. The spots are often directly along the seam of the mattress. With bed frames, they are on the slatted frame and in gaps and joints.


>          Note that these insects are often able to get into gaps regardless of how tightly the wood is screwed together.

            After treatment, sleep again in your bed! That way you avoid spreading them and can determine how successful the treatment was.


Be sure to inform your pest control expert as to whether you have already used insecticides and to what extent (risk of adverse interaction). It is possible to clear up a bedbug infestation with just one treatment if properly prepared for. With less preparation and a high initial infestation, a second and third treatment might be necessary after 10-20 days. If there are no bites after about 2-3 months, you can rest assured that none of them are left.

Bear in mind that the commercial products available on the open market for spraying rooms are not alone sufficient for an effective control.



Preferred hiding places of bedbugs:


-           in alarm clocks

-           behind baseboards

-           around door and window frames

-           around window ledges and frames

-           behind telephone jacks, electric wall plates, fuse boxes

-           around electric tubing and cables

-           along seams and folds of the mattress and the sheets

-           in the bed frames and headboards

-           in hollow legs of the furniture and upholstery

-           on bedside tables and nightstands and in the drawers

-           on curtains and curtain rods


If you find no indications of infestation, it is a good sign for a start.


If, on the following day, you find you were bitten and it itches terribly, then have the room checked for bedbugs.


Often, it is not the fault of the hotels and hostels that they have bedbugs. If an infestation is confirmed, you will see what kind of hotel you have landed in by how professionally the persons in charge react.



If it s already too late and you are on your way home with bedbugs in your luggage, then you must do the following:


-           go directly into the bathroom with your all your luggage

-           put the suitcase(s) into the bathtub and take off your clothes

-           get fresh clothes out of your flat und put them on

-           then get 120 liter-trash bags and put the clothes in them

-           also put the suitcase(s) into a trash bag and place it  (them) in your cellar

-           wash everything at 60°C about 30 min, if possible, or use a laundry dryer at 40°-45°C for about 30 min

-           infested sensitive articles can be thoroughly rid of bedbugs by placing in a freezer for 10 hours at -17°C

-           We do not treat articles of clothing (e.g. virgin wool, silk, sensitive fabrics) and electronic equipment (e.g. TV, radio, alarm clock and so on). They can be stored in plastic bags (bedbugs die of hunger within 6 months)

-           Electronic equipment can also be fumigated with insect-strips in plastic bags for several weeks. Due to the high gas pressure emanating from the strips, the insecticide gases permeate deeply into the equipment.
