Comments & ID Thoughts

Have killed and trapped many over 3 day period. About 10. Don’t know where they are coming from or what they are and I’m concerned. Do they bite? What happens if they do? Worried about my daughter.
What can I do to prevent them? Where do they hide?
They don’t seem to move too fast for a spider.

Hi, welcome to Spider ID. 🙂 This is a Woodlouse Hunter, Dysdera crocata.

You can reduce the number of spiders you find in your home by sealing cracks around floors, doors, windows, foundation etc., vacuuming everywhere and emptying the canister outside. I usually find these under rocks, they prey on pillbugs/rollie pollies/woodlice.

Insecticides are only a temporary fix if the openings that spiders are getting in through aren’t sealed off. These usually keep to themselves and are generally not anything to worry over but if you’re seeing a lot of them out and about you can reduce the chance of being bit by keeping clean laundry off the floor and putting it away, prevent bed sheets from coming into contact with the floor. If you think you know where they’re coming in at but can’t seal the area sticky traps are an alternative (looks like you already have some).

Are they poisonous? It has killed 2 spiders that we also captured temporarily.
