The cup-and-card method, step by step
Identify it first, from a safe distance
Most house spiders are harmless and eat other pests. A short check against our spider identifier saves you from killing a beneficial spider.
Get a cup and a stiff card
A clear plastic cup lets you see the spider. A postcard or thin cutting board makes a slide for under the cup.
Place the cup over the spider
Approach slowly. Lower the cup straight down. If it scuttles, wait — most spiders freeze again within seconds.
Slide the card under the cup
Press gently against the floor and slide the card across until the spider is fully inside the cup. Keep the cup tilted slightly upward.
Release outside, away from the house
Walk at least a few meters from the wall. Tip the cup gently in a bush, garden bed, or wood pile. Most spiders won't come back inside if their food (other pests) is outdoors.
Not sure what type of spider it is? Check our spider identifier hub first — many spiders that look scary (wolf, cellar, jumping) are completely harmless and beneficial.
If you really can’t catch it
A vacuum cleaner with a long hose attachment is the next best option. The suction is enough to handle even large wolf spiders. Empty the canister outside immediately so the spider doesn’t crawl back out.
Stop spiders coming in
- Vacuum corners and behind furniture monthly.
- Seal gaps under doors and around windows.
- Replace bright white outdoor bulbs with yellow “bug” bulbs.
- Move firewood and leaf piles away from house walls.
