No taboo subject: vermin in the house

In many a kitchen cabinet, behind baseboards, in the basement and under the mattresses teem, crawl and eat them: mites, cockroaches, rats and mice, beetles, moths, ants and bedbugs - they and many others are uninvited house guests, the best way as soon as possible, before they cause more damage. Because some of these pest spirits transmit diseases. But not always you have to use concentrated chemistry: There are a number of simple means and tricks that seem fast and almost always reliable.

Vermin in the apartment

Sometimes you see them, at night, very fleeting, and if you look closely they are gone again - because most shy the daylight: the speech is of cockroaches, also called cockroaches. Silverfish and bedbugs, rats and mice are also rarely seen.

Moths and beetles in food, on the other hand, occasionally fly out of the kitchen cupboard - but then they have already spread enormously and one can assume that several generations of the apartment in the joints, cracks, cabinets, carpets and clothing colonize. This is disgusting and unpleasant, but does not necessarily have something to do with poor hygiene. Many vacationers have brought unnoticed a cockroach from far away countries in their luggage, and not infrequently hide tiny beetle larvae in flour, cereals or nuts and begin their nuisance secretly and for a long time unnoticed.


As soon as it gets warmer outside, the flies and ants come in. Especially annoying is the housefly: The "Musca domestica" is 8 mm long, is dyed gray, decorate her chest four dark vertical stripes. The females lay 2, 000 eggs mainly in manure, feces, compost heaps and refuse sites, ie wherever organic substances decompose.

The fly loves human and animal excretions such as excrement or festering wounds. It is magically attracted to food and leaves pathogens there - it transmits the pathogens of typhus, cholera, dysentery and polio. Best of all, it is therefore necessary to close the windows with fly screens and to hang glue traps or glue ribbon catchers.


They are still the most innocent of the house guests: The way ant and turf ant are common in the northern latitudes. They have a brown body and prefer to build their nests in sandy and sunny spots in gardens or on roadsides, often under stones and slabs. The path ant likes to nest in gardens, under stones, tree bark, in the lawn or in wall columns. Both ant species live on sugary substances and meat. In homes and storerooms, they are attracted by fruits and honey as well as fresh meat.

The rapidly formed ant roads lead directly to the nests. In old buildings, ants can additionally attack wood. As a bait, the website of the exterminator recommends, you can set up a plate with a sweet liquid like honey water or raspberry water. A mixture of borax and powdered sugar is intended to destroy the ant brood.

Another remedy is baking soda: for a 4 m long track already half a packet is enough. It puffs up the animals, they burst. It is less brutal to drive away ants by putting lemon juice, lavender oil, lavender flowers, marjoram, cinnamon or tomato leaves on the ant trail.


Cockroaches (the "common cockroach") are the messengers from prehistoric times: over 300 million years ago they populated the earth, survived ice ages, earthquakes, droughts, and also many poisons can not harm them. In our latitudes, the tawny Blattella germanica occurs, it is about 13 mm in size, has wings, but does not fly. The females carry packages of 20 to 40 eggs for four weeks, which they throw off in all possible places. These egg packets are very resistant because of their chitin shell. The larvae hatch shortly after the egg is released. They mutton several times, after two to three months they multiply. Their abilities are amazing: they can climb walls and jump up to 10 cm.

There are about 3500 cockroach species. In the meantime, even the American cockroach "Periplaneta americanadie", which measures more than five centimeters and can fly well, is said to occur in southern Europe. The fact that they are simply eating everything, most of the food, of course - their favorite environment is kitchens, especially canteen kitchens - has saved them over millions of years. They eat organic material of all kinds such as tissue, leather and paper, but especially like moist, soft and rotten foods. Cockroaches can also survive around 40 days without food. But until you see them, a whole time passes and there are guaranteed to be several generations if you happen to see a cockroach.

Cockroaches, according to the doctors' newspaper, can transmit many bacteria, viruses and fungi. "Contact with them can lead to diarrhea, colon cancer, hepatitis A, anthrax, salmonella or tuberculosis and moulting can cause allergies, but in rural areas cockroaches are particularly feared because they can cause foot-and-mouth disease in stables."


There are many moths and beetles that are particularly fond of food, including the corn moth, the flour moth or the dried fruit moth. The caterpillars of the flour moth eat, tense and pollute flour products, baked goods and dried fruit. You usually only discover them when the web has formed - you can recognize many other types of moths.

An open vinegar bottle between foods is intended to drive away moths. It is also possible to use sticky traps with pheromones for combating dried fruit, storage and flour moths. These fragrances attract males over long distances to the females or just to the glue. It is important, especially in the flight time of the moths - May to September - to make sure that the windows are closed by fly gauze, as the males are lured by the traps only into the house.

Clothes moths do not like cedar oil, they also despise lavender, sage, thyme and camphor. A bag containing dried orange peel or dried clover should also help. They also do not like printing ink. A tip z. For example, for stored winter items: Wrap garments first in fine paper and then in newsprint. Dress already infested clothing in plastic and put it in the freezer for a day or two.


Often you will find the grain beetle in the house, the most widespread in Europe cereal pest. Like the rice beetle, it was also introduced and reproduces very quickly in heat. The brown, sometimes black corn beetle can not fly, but also crawls enormous damage. The photophobes prefer to nest in the middle of a cluster of crops. Warehouse grain is best attacked by him. Like the rice beetle, it multiplies by laying eggs in grains and pasta. The larvae eat grain grains completely from within.

Even smaller and completely flexible in feeding is the 3 mm small bread beetle, the farsighted often do not recognize - he eats in addition to baked goods and soup cubes, chocolate, pet food or dried fish. Also salt dough pastry and chile spice, paper or cardboard is not safe from them. All food that has been attacked by the pests must be disposed of immediately. Everything that was not in sealed containers should be examined. The cabinets and chambers are thoroughly cleaned, for example by suction, and blown hot - this is especially true for the cracks and crevices. The hot air kills the greedy larvae.

It is important not to store loose food in cupboards: tightly closed screw jars for muesli, rice and pasta have proven to be the best. Too much moisture and heat always attracts pests, so you should always look for damp places behind cabinets.

Drive away rats and mice

Everyone knows that rats and mice transmit diseases, the most common are salmonellosis and cholera. Mice destroy and contaminate food and feed in animal houses, nibbling through paper, boxes, loose plaster, textiles, plastic insulation, floors, doors, and cables, causing material damage.

Rats eat everything, but are very picky. Thanks to their highly developed sense of smell and taste, they react with suspicion to the unknown. Thus, they can associate discomfort and death of their conspecifics with a poison bait, they disdain the bait. Worldwide, around ten billion rats kill about a fifth of all food and feed every year due to feeding and contamination. Through their faeces and urine, they transmit the causative agents of salmonellosis, foot-and-mouth disease, swine fever, typhus, cholera and many other diseases to domestic animals, livestock and humans.

Prevention is the best protection: rats and mice usually come through cellar windows, drains and other entrances into the house; they must be locked with lattices and flaps, food and food or waste such as the bio bin should be well sealed. You must never dispose of food through the toilet, it attracts the rats through the channels and they come through the pipes into the house. Mice are sold with a turpentine soaked in turpentine and placed in the mouse holes.

The smell of chamomile, camphor or peppermint should drive away mice. Mice also do not like mixing dried, finely chopped oleander leaves with dry sand and spreading them deep into their holes. Mouse holes are sealed with a cork dipped in turpentine or cayenne pepper. Cayenne pepper on shelves distributes them as well.

Peanut butter is the most effective bait for rat and mouse traps. In addition, in the case of a large number of rats in the cellar, pest controllers recommend spraying the cellar rooms with yellow lime every spring and adding the lime color iron vitriol (iron (II) sulphate). And finally: A cat in the house is still the best protection!

Who helps with vermin in the house?

Competent contact persons for pest control are the local health authorities, the German Pest Control Association e. V. (DSV), the Association of Regional Pest Control e. V. or the Federal Institute for Consumer Health Protection and Veterinary Medicine. Incidentally, sensitive people or allergy sufferers should avoid direct contact with insect repellents, which are available as sprays or as an electric evaporator. This can manifest itself in skin irritation, tingling or coughing.

Mosquito nets over the bed to mosquito repellent are therefore suitable for flying insects in the bedroom for persons strongly affected by allergies. Bait boxes or sticky traps are usually harmless, but you should get in any case in the specialized trade advice.
