Features: Working, only 2 – 2.5 mm length, yellow-amber coloured, the pin of the back side of the body is dark-coloured, they are heat lovers and appear only in well-heated spaces. The sexed animals nests can be found for example in masonry, at large distances from the food point.
Damages: They crunch food with large quantities of albumin or sweet nutriments. In hospitals, there is a danger of proliferation of the pathogen germs. Also, they constitute a danger for large kitchens, bakeries, sweets factories, etc.

Fighting: Crunching lure doses for ants, jell for ants, sprays with a contact insecticide.
Features: Around 5-8 mm long, strongly flattened, foxy-brown colored. The larvae emerge from the egg, becoming adult insects after covering five stages. Their shape is similar to the adult insects, but the color is yellow-brown. After sucking blood, they get seriously thickened and get a dark red, up to black color. They hide in their caches during the day, such as cracks, mattresses, pipes, paintings, etc. The adult specimens can endure coolness and can live without food for weeks. Most often they invade bedrooms.
Damages: The sting of the mature insect and the larvae is usually performed in the dark. The blood is sucked in for 5 -10 minutes. The liquid secreted by the salivary gland during this time is toxic, and in most people generate rashes which can last and itch even after seven days. Thus inflammations of the skin on large surfaces, general health condition disorders and eyesight weakening result. In case of a strong attach, their unpleasant, sweet smell in the room creates a feeling of disorder.
Fighting: contact insecticide.

Features: 1.5 – 4 mm length, brown – up to foxy-brown colored, the dog fleas (with oblong head) and cat fleas (with short head) live close to storing facilities, lay up to 400 eggs mainly in the surroundings of the host animal, the larvae are threadlike, without legs, around 5 mm long. The life duration of a generation is 4-6 weeks, fleas can live in hunger for weeks.
Damages: The flea causes painful stings for humans, cats and dogs and sucks their blood. Often it stings several times consecutively and sucks until it is filled. The itchiness can last for days and it results in rashes and papule. Bearer of tapeworms.

Fighting: Contact insecticide
Features: Black-grey up to grey-yellow colored, flat crustacean, the adult species reach a length of around 15 mm. They can be found in laundries, cellars, behind shelves, in boxes, heaps of potatoes or in other materials stored in humid places.
Damages: They survive by eating vegetal supplies. Damages are not generally serious in the houses and cellars – only small feeding areas on potatoes, fruits and vegetables. They are however inconvenient and bothersome.
Fighting: contact insecticide
Features: it avoids light, has no wings, rapid insect with a length up to 12 mm. Silver-grey colored, they develop at room temperature during approximately one year and have a total life duration of two years. They are found in humid places and often in the canteen, bathroom, kitchen, laundry, closet, in new buildings where the material is not totally dry, etc.
Damages: their favorite dishes are substances containing large quantities of carbon hydrates and sugar, glue, sticking substances; they generate damages as a result of grazing starched textiles, synthetic fibers, leather items, book covers, etc.
Fighting: Lure doses for silverfish.
Features: This spider variety belongs to the curly spider class and does not make isolated horizontal or vertical webs. The wall spiders generally use a rippled thread to make their web, which is usually irregular and 5 mm long and stuck directly on the house wall. They live behind or above the web, in wall cracks. If the outside wall is a little bit ruined, the spider rapidly propagates in those places.
Damages: Their webs collect insects, food residues and a lot of dust and houses façades will shortly appear dirty.
Fighting: The façade is cleaned and then immediately.....is applied. ....(unfinished sentence in German)
Features: The top of their body has a dark up to black color and the underneath is grey, the body and the tail reach 9 cm length for each animal, they have a high multiplication capacity. They bear 4-8 offspring at one time, 4-6 times a year. They preferably live in dry rooms, but can easily adapt to various conditions.
Damages: They eat food, textiles, paper, leather, etc. and generate dirt through their excrements. They transmit diseases, such as trichinosis, paratyphoid fever, etc.

The caterpillars get out off the eggs after approximately 14 days. The duration of development up to the butterfly stage takes 3 months at room temperature. 3-4 generations a year in heated rooms and two generations in unheated ones.
Damages:. Most white-yellow colored clothing moths generate holes and callow places in woolen materials, fur, carpets, etc. Most often they attack the wool threads, textiles and furs that haven’t been worn for a long time.
