Question By: In New Zealand, spiders don't follow a strict seasonal schedule, but their activity tends to peak during the warmer months of spring and summer, roughly from September to February. This period aligns with their breeding season, when many species become more mobile, either searching for mates or establishing new webs to catch prey. The rising temperatures and longer days also boost insect populations—spiders' primary food source—making it an ideal time for them to thrive. You're more likely to spot them scurrying across floors, spinning webs in corners, or lurking in gardens during these months.
That said, spiders don't vanish in autumn or winter (March to August). Some species, like the common house spider, remain active indoors year-round, especially in cozy, heated homes where food is still available. Others, such as the katipō, a rare native spider found on coastal dunes, may retreat or become less noticeable in cooler weather, conserving energy until conditions improve. White-tailed spiders, often blamed for bites, also don't clock out seasonally—they're just as likely to hide in your laundry pile in July as in January.
Weather plays a role too. Wet, humid spells—common in New Zealand's temperate climate—can drive spiders indoors seeking dry shelter, regardless of the month. Late summer into early autumn (February to April) might see a final flurry of activity as some species prepare for cooler times ahead. For those keen to avoid eight-legged encounters, spring and summer are the key seasons to stay vigilant—shake out shoes, clear webs, and keep clutter in check. While spiders never truly take a holiday in New Zealand, their presence feels more pronounced when the sun's out and the air's warm, making those months the unofficial high season for arachnid activity.
