Dry rot treatment Dry rot treatment Dry rot treatment refers to techniques used to eliminate dry rot fungus and alleviate the damage done by the fungus to human-built wooden structures. Dry rot ("Serpula lacrymans") is considered difficult to remove, requiring drastic action. Remedial timber treatment and damp proofing companies typically recommend stripping out of building fabric beyond the visible extent of the infestation and the use of fungicide. More holistic approaches attempt to eradicate dry rot by controlling the local environment to reduce timber moisture levels and increase ventilation in order to promote drying. The first priority when treating dry rot is to
Serpula tidal fashion. In the central circulatory system, the blood moves anteriorly from the tip of the abdomen to the front of the thorax through a sinus enveloping the alimentary canal, and posteriorly through a ventral blood vessel. The ventral vessel and the sinus communicate with each other by segmentally arranged ring vessels, and by a dorsal vessel, a transverse vessel, and a pair of circumesophageal vessels situated at the anterior end of the thorax. The dorsal vessel in some of the larger serpulids, like "Serpula", possesses a valve and a muscular sphincter, probably to prevent backflow of blood from the
