Bed bugs, fur beetles, cockroaches, silverfish, red flour beetles
Those are pests that must not be tolerated. If you find them in your apartment, immediately report a fault in section "Online Janitor" at www.koas.fi. Pest control professionals will chart out the situation and take care of the exterminationprocedure.
Below is a description of the most common household pests in Central Finland. The specialist interviewed is exterminator Jari Kansanaho from Pohjolan Desinfiointi Oy.
Bloodsucker bed bug
Bed bugs are about the size of an apple seed, broad, flattened, brown and ill-smelling. They can survive for months without feeding. Hungry bed bugs are lighter in colour. Bed bugs hide behind wallpapers, under floor battens and in the cracks and crevices of bed side furniture. They spread in places where many people overnight, such as hotels. Since travelling is today easier and very common, they have become a nuisance particularly in Southern Finland. Bed bugs and their larvae suck blood from people and pets. Bites do not always leave any symptoms. Sometimes the site of the bite is itchy, reddish and develops local swelling. Bed bugs do not spread diseases in Finland. Bed bugs are brought to urban apartments from travels abroad. In Finland, bed bugs are found in places where bats live: an overnighter can transport bed bugs from boarding houses located in sparsely populated areas. Also, when buying furniture from recycling centres and flea markets, one may get inhabitants into the bargain! Bed bugs cannot fly. Bed bugs die in a few hours at temperatures below -15°C. In winter, when you come back home from a travel, take your luggage to the balcony. All development stages of bed bugs also die at a high temperature. Pests will die if you keep your luggage in the sauna at 60°C for a few hours. It is also recommended to "disinfect" empty removal boxes at a freezing temperature or in a hot sauna. Bed bugs do not stick in clothes.
Clothes-eater fur beetle
Fur beetles are about half a centimetre long dark brown insects with a yellowish sawtooth figure on the back. Fur beetles are poor flyers. The larvae have a tuft of hair at the rear part of the body. The larvae of these beetles make tiny holes in natural-fibre clothes and carpets. Dirty textiles are its favourite. The larvae hide in intermediate floor structures, under battens and carpets and in cupboards. They spread via the ventilation channels to other apartments in the horizontal and vertical directions. Their presence can also be discovered based on empty larval shells.
Squirming like a worm, the silverfish is about 1 cm in length, covered by light scales and likes to eat cardboard. It lives in damp areas and is common on the lowest floors. It travels from one apartment to another via pipe leadthrough openings. Fast-moving silverfish live in dark and slip to the drain when you switch on the light in the bathroom. The silverfish does not use food for nutrition. In addition to cardboard, this insect also eats fluffy skin tissue in the sinks and shower drains. The silverfish is not hazardous for health; however, like many other pests, it will enjoy its stay the better, the more there is dirt and junk in the household. Silverfish are common in damp areasand rooms with a floor drain, such as a laundry room, but they are not an indicator of water damage to the house.
Red flour beetles lay their eggs in flour
Red flour beetles are 3 mm long, dark-brown, flattened crawling insects. Red flour beetles can fly and they are carried to households inside flour, flake and peanut bags and packages. Usually, they get into food already in flour mills or storages. Red flour beetles lay their eggs in flour bags. They do not spread diseases but, when present in great numbers, will spoil food. They can be found at home inside the back walls and crevices of kitchen cupboards.Spreading of food pests can be best prevented by discarding old flour. If pests appear inside the cabinet, recently bought flour can be used after keeping it in the freezer for a week, as the eggs will be destroyed at a low temperature. Their spreading can also be prevented by storing flour in metal jars.
Cockroaches measure from one to three centimetres. There are thousands of different species, which have survived to the present day from ancient times. The cockroach has a large carapace, long antennae and wings on its back. During the day, cockroaches rest in the cracks and crevices of floors and walls and, when the night falls, march to the kitchen to look for food. Thanks to its flattened body, it can hide almost anywhere; it moves like a lightning, climbs on the wall and can even jump. It does not come to the bed. Cockroaches may be brought home from hotels when travelling abroad. At the old times, when the hygienic level was lower than today, a domestic cockroach species, croton bug shiner (8–13 mm), lived in the Finnish households. Cockroaches increase in population at a very rapid rate. Females produce between 30 and 40 larvae at a time. The species has 2 to 3 generations in a year. Cockroaches spoil food with their faeces and spread diseases, for example, salmonella.
