…uses that are built directly on the ground are often visited by the garden ant. The ants settle directly under the concrete floor, where they do penetrate through cracks, like foot panels, and pipe penetrations. They can also settle between the insulation material of the wooden and concrete floor, this will however, damage the wood floor. The first signs of ants inside the house are small piles of gravel or sand that appears at panels. Such piles…

(8) The pharaoh ant and the common black ant
…colony, allow the pharaoh ant to reach far in large facilities. The common black ant is not synanthrope anywhere because it depends on aphids. Normally it lives outdoors, but in cases where a colony is located below or adjacent to a heated house, the slightly higher temperature can cause the ants to become active earlier in the spring than it normally would. It forces the common black ant to find its food indoors until it gets warmer and aphids ap…
Jet ant
Latin: Lasius fuliginosus The jet ant or jet-black ant is in danish called “orange ant”. The danish name is not because of the color, because the jet ant is not orange. The danish name comes from the fruit orange. Because the ant has a sweet orange scent, which scent can be enhanced when squeezing the ant so it is believed that the scent comes from within the ant. This type of ant is widespread throughout Denmark, except West Jutland. Appearance…
The common black ant
Latin: Lasius niger. The common black ant Season for black common ant This is the species most frequently encountered indoors. An ant colony usually consists of a dozen thousand ants, and the colony is placed in the ground. In buildings, the ants establish colonies in cavity walls and under floors. Outside, they have a certain fondness for building colonies under tiles. They penetrate anywhere through cracks to seek food. The common black ants li…

The queen of the yellow shadow ant kills the queen of the black ants and exploits the workers of the black ants to found her own colony. Damage When the yellow ant settles down and builds nests in houses, it most often happens under the floor or in connection with other woodwork. Here they start digging material such as gravel and soil from the subsoil, which th…

Hercules ant
…not without reason that the Hercules ant has earned its name. The Hercules ant is the largest ant in Denmark. However, the ant, which also goes by its Latin name Camponotus herculeanus, is not very common in Denmark. It is only found in North Jutland and North Zealand, where it lives in the areas’ coniferous forests. Appearance Although the Hercules ant as described is the largest ant in Denmark, not all the species’ ants are the same size. The qu…
The pharaoh ant
…te households. All kinds of food may be eaten by this ant. Like the common black ant, the pharaoh ant also has appetite for jam, sugar and honey. Meat products, cheese, high-fat foods, dead insects, carrion and mouse droppings are also among the things that this ant eats. In hospitals, pharaoh ants crawl into sterile products and under the patients’ bandages. Furthermore they seek out waste, carrion and drains, so there is no doubt that the pharao…

…can lay their eggs. The eggs are placed in clusters on the leaves of the plants. The eggs of the common green lacewing are about a millimeter long, and they sit on the end of a thin stalk of about ½ centimeters. Aphids are the common green lacewing larvae’s favorite food, and the small larvae are even called aphid lions due to their large appetite for these. If the garden has been invaded by aphids for a year, one would therefore expect to find ma…
Pharaoh ant

But pharaoh ants are not just an annoying nuisance. They can also pose a risk of infection if they manage to enter a hospital, where they can find bandages, wounds, or sterile packaging. Prevention and pest control If the pharaoh ant intrudes into a priv…

Ants
…ants will usually settle in a cavity wall or under the floors. The common black ants are species which are highly dependent on aphids whose sugary excrement constitute an important part of their diet. They can take care of and protect aphid colonies against larvae of hover flies, ladybugs and other of the aphids’ enemies. In some cases, they may even build “stables”, small chambers for the protection of a colony of aphids which feed on roots. The…
Small black or garden ant
Latin: Lasius niger Black garden ant These are the ants most commonly seen on verandas and in the house. They live in the ground, frequently under rocks or flagstones, and they will often penetrate under the house itself, particularly if it has been built directly on the ground. Ants frequently build nests in the insulation layer and from there they penetrate up into the house itself through the cracks which inevitably appear in the cement. Garde…

Jet black ant
(Latin: Acanthomyops fuliginosus, lasius fuliginosus) Jet black ant These shiny, black ants normally live in trees, and they have a distinct smell of oranges. They can establish themselves in the dead parts of trees, in stumps and in wooden floor boards damaged by damp. They gnaw extensive tunnels and holes in the timber, and they fill them with a dark papery material which they make by mixing gnawed wood fragments with saliva and particles of ea…

…The larval tunnels lie between the bark and the wood (see p. 139). Small black ant exit-holes in timber Small black ant These ants form labyrinthine tunnel systems in soft, crumbling timber which has been attacked by fungus or possibly by wood-boring beetles. The surface of the timber takes on a typical rounded and polished appearance. When the colony is deserted the tunnels are completely empty ( see p. 145). There are other ants which also a…
Black fly bites
…g. 40. Newly-hatched black flies can form large swarms in May. Only female black flies need blood, and they bites outdoors at all times of the day. Most black flies prefer other host animals; however, they bite humans if more suitable hosts are not present. When a black fly is about to suck blood, it is not easy to chase away. However, it is easy to slap. Its mouth parts are short. It scrapes a small hole in the skin and drinks the blood from the…
Black rat
…placed by the brown rat. Black rats were responsible for spreading plague (Black Death) in Europe during the Middle Ages. In most parts of Europe black rats have been completely eliminated, but they continue to arrive in ships from overseas and are therefore still present in certain large ports. They are associated with man to an even greater extent than the brown rat, but being more warmth-loving they do not occur out in the open in central and n…
Common woodboring beetles

Damage There is no doubt that the common woodboring beetle leaves harmful traces that are highly visible. As the larvae get bigger, they will gnaw further into the wood and thus expand their boreholes. This results in small holes in the woodwork. In the case of a powerfu…

It was the black rat, or rather the fleas of the black rat, that caused the plague epidemics which under the name “the Black Death” depopulated much of Europe in the Middle Ages. In the Nordic countries, the black rat is undoubtedly completely gone, but it is occasionally imported by ships from overseas. The black rat lives in higher temperatures than the brown rat, so it does not appear in fields in northern Europe. The…

There are fifty different species of black flies in Denmark. They all need running water. Some species mate in streams, others in brooks and ditches….

Hercules ant on infested wood The ants gnaw their tunnels in the soft spring wood, and leave the summer wood alone, so that in a transverse section of the tree trunk the tunnels appear as numerous regular rings. In a longitudinal section the summer wood remains as a series of lamellae, pierced here and there by openings which connect the different tunnels. There have been cases wher…

The flower bugs can turn raspberry picking into a dubious pleasure. Flower bugs are especially encountered in the late summer. Flower bugs are useful animals, which help keep the aphids-population down, and it’s not reasonable to fight them with poison. People who are…

The damper it is the better, provided the timber is not soaking wet over a long period. Serious infestations by this beetle often occur, therefore, in kitchens, cellars, outhouses and stables which are sometimes rather damp. This species does not thrive if the air humidity is constantly fewer than 50 % so it will not survive in the dry…

They dry out to round spots which sometimes have a small ‘tail’ (see opposite page).

They normally produce several such…
