Hercules ant

…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.

This is one of the ant species in which a single mated queen can found a completely n…

Bryobia praetiosa

…ust breed parthogenetically. These mites cause absolutely no damage in the house and they very quickly die in the dry climate. They are completely dependent upon the presence of plants on which they can feed. Normally they are only seen in houses where the lawn goes right up to the walls, so the most rational method of control is to create a break between lawn and wall. This can easily be done by having a strip of gravel or stone chips ½ – 1 m wid…

Common furniture beetle

…beetles, which only live a couple of weeks, can fly and are often confused with small flies. Shortly after emergence they mate and the female starts to lay eggs.

Animals that attack textiles
