The term glomerulonephritis (GN) covers a group of conditions in which there is injury in the glomerulus, the filtering unit of the kidney. This can occur either as a primary glomerular disease, or secondary to drugs, infections or tumours (see Secondary Glomerular Disease, pp 464â466 of this issue).
As insects are spiders' main prey, it is likely that they would impose strong selectional forces on the foraging behavior of spiders. Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them.
The best way to get rid of spiders if you have many is to get the voracious bug and insect eater-the ladybug beetle. These small creatures eat close to 50 bugs a day. I have several of these small beetles in my house.
