Are Woodlouse Spiders Poisonous to Dogs?

Are Woodlouse Spiders Dangerous?

Woodlouse spiders are not dangerous to dogs or humans, despite their somewhat fearsome appearance. Their primary prey is woodlice, hence their name. When threatened, they might bite, and while the bite can be painful due to their large fangs, it’s not medically significant.

Woodlouse spider bites on dogs might cause temporary discomfort and localized swelling but generally do not lead to serious health issues.

Are Woodlouse Spiders Venomous?

Woodlouse spiders are venomous, but their venom is specifically designed to incapacitate their preferred prey, the woodlouse. It does not pose a significant threat to mammals, including dogs and humans.

If you have a dog bitten by a woodlouse spider, you might notice a localized reaction such as redness or swelling, but severe reactions are unlikely.

Training the “Leave It” Command

One way to protect your dog from potential spider bites is to train them to respond to the “leave it” command. Here’s a basic guide on how to do so:

  1. Start with a treat in both hands. Close your fist around one treat and present it to your dog while saying “leave it.”
  2. Wait until your dog stops trying to get the treat in your closed hand and moves away. Immediately reward this action by giving them the treat from your other hand.
  3. Repeat this process until your dog consistently moves away from your closed fist on command.
  4. Gradually increase the difficulty by using more enticing treats, introducing distractions, or practicing in different environments.

These steps will get your dog to stay away from woodlouse spiders, but it’s important to remember that the underlying behavioral issues (prey drive, curiosity, overexcitement, etc.) that were causing all of this to begin with will still be present. And until you address those, any positive changes you see are only going to be temporary.

“Well, how do I make these changes last?”

How to Get Rid of Woodlouse Spiders

To get rid of woodlouse spiders from your house or property, you can implement a combination of habitat modification, mechanical removal, and professional pest control. These spiders are harmless to dogs and people, but their presence may still be unsettling.

Woodlouse spiders, recognized by their reddish-brown color and robust body structure, prey primarily on woodlice. They are not harmful to dogs or humans, but if their presence is bothersome, here are some strategies to get rid of them:

  1. Modify their Habitat: Woodlouse spiders thrive in damp, cluttered environments. Keeping your home and yard clean and dry can deter these spiders. Ensure there’s no standing water or damp woodpiles around your home, as these are attractive breeding grounds.
  2. Mechanical Removal: If the spiders are not numerous, you can remove them mechanically. This involves capturing the spiders and releasing them away from your home. Always wear gloves when doing this to avoid potential bites, even though their venom isn’t harmful to humans or pets.
  3. Professional Pest Control: If the infestation is severe, consider reaching out to a professional pest control company. They can implement more aggressive strategies to manage and eliminate the spider population.

Remember, woodlouse spiders pose no significant threat to your dog or other household members. However, by keeping your home and yard clean, dry, and clutter-free, you can create an environment that’s less inviting to these spiders, ensuring you and your pets can enjoy your space without worry.
