What does God say about killing spiders?

What God says about killing spiders is not explicitly stated as direct commandment about spiders in major religious texts like Bible, Quran, or other scriptures, but general principles about treatment of creatures can be inferred. In Bible, there is no verse that says thou shalt not kill spiders or thou shalt kill spiders, spiders are mentioned only a few times symbolically, for example Proverbs 30:28 praises spider's diligence saying spider taketh hold with her hands and is in kings' palaces, and Job 8:14 uses spider's web as metaphor for fragility of false hope, and overall biblical view emphasizes God as creator of all creatures and humans as stewards of creation in Genesis, suggesting respect and responsible care rather than wanton killing, but also allows killing of pests for safety and hygiene. In Islam, spiders are respected because of story where spider web protected Prophet Muhammad in cave during Hijra from enemies, so many Muslims avoid killing spiders unnecessarily and view them with respect. In Buddhism and Jainism, principle of ahimsa or non-harming discourages killing any living creature including spiders. So God does not say killing spiders is forbidden or required, but general religious principles suggest respect for creation, avoiding unnecessary killing, and humane relocation of harmless house spiders is preferable, while killing may be justified for safety if dealing with venomous species like black widow or brown recluse that pose danger, with intent and necessity being important considerations.
