The electrically charged webs of the Galvantula do not solely trap prey, but also provide an extremely tensile surface which can also conduct electricity. Because of these useful properties, Galvantula thread has long been harvested throughout Unova, and now provides the structure for most construction, as it has since the dawn of the electrical era.
Most Unovan buildings today – and a growing number overseas – have only a small amount of brick or steel in their construction. What traditional materials they have serves two purposes; to provide cheap surfacing (for Galvantula thread is extremely expensive) and to insulate the people inside from electrical shocks. Galvantula silk doubles as wiring, for it conducts this pokemon's electricity; the ability to combine wiring and load-bearing is what makes this substance cost-effective over other materials. There is a modest downside to its use in that many of these buildings form quite natural habitats for the pokemon which created them in the first place. However, these Galvantula are largely tolerated, for they rarely attack humans and if anything add to the resilience of their structure – the only problem is the occasional arachnophobe's scream.
Humans who do not specialize in architecture often notice Galvantula webs in the forest or on pokemon farms, and mistake them for something soft and easy to break through. Although Galvantula have been trained to not eat humans, the electrification these hapless individuals suffer can be fatal if they are not retrieved from the web in time; it is all but impossible to break out on one's own. Some have questioned the safety of Galvantula silk in buildings for similar reasons, for structural damage can at times leave these webs exposed. But should any building become so damaged, falling steel or brick is a far more likely cause of death.
