Spiders & arachnids: types, identification & control
Most spiders in a home are harmless hunters that followed their food indoors, but brown recluse and black widow bites need medical attention. Markings, leg posture, web shape and where the spider was found separate the dangerous species from the lookalikes. Scorpions are arachnids too and are handled with strict exclusion rather than spraying.
