  • Question
    I am planning on storing my luggage in the basement in plastic bags. Would white bags be better than black bags to discourage black widow spiders?
    Community Answer
    Unfortunately, the color itself will not discourage black widow spiders. White bags, however, will make it easier for you to spot them.
  • Question
    How do I safely remove black widow egg sacs?
    Community Answer
    Whatever you do, do not crush it. Hundreds of baby black widows will emerge and roam free, and you will have a much bigger problem on your hands. Instead, get some gloves and try applying a safe pesticide onto the egg sac. Drop it into a container or an airtight bag and throw it out once you're done.
  • Question
    Can I get rid of them without killing?
    Community Answer
    You might have to kill, because the babies from prior will stay where their mom set them up.
  • Question
    Spiders are avoiding our sticky traps. They used to crawl right in. We are using the same brand as the last two years; sometimes we alternate brands. Are the spiders becoming trap smart?
    Community Answer
    Have you thought of covering all the areas? For example, instead of just covering the window frame, cover the whole window sill. Also, check your traps for effectiveness, the spiders may have just freed themselves.
  • Question
    If I find one black widow spider, is it safe to assume there are more in the house?
    Community Answer
    You should always assume there are more if you find one. Check your home thoroughly, including all the dark corners and crevices, and keep a lookout for disorderly webs (as that is a good indication they are still around). There are things you can do to prevent them from coming back in the guide above.
  • Question
    How long do I have if I get bitten by one?
    Community Answer
    It depends on whether or not you have a reaction to the venom, but most people recover within a 24-hour period with treatment. If you are bit, seek medical attention immediately and you shouldn't have anything to worry about.
  • Question
    What do I do if an egg sac hatched near my front door and there are baby spiders everywhere?
    Community Answer
    Call an exterminator. It may not seem nice, but it definitely is the best option. If the spiders get older, they can be dangerous enough to hurt you and anyone else in your home.
  • Question
    How soon do black widow spider eggs hatch after they are laid?
    Community Answer
    They hatch in roughly 15 to 30 days, but it is better to exterminate them immediately.
  • Question
    How painful is the bite?
    Community Answer
    It varies. If one is expecting to be bitten, the bite can feel like anything from a momentary scratch to a pinprick. If not expected, the bite will, more than likely, go unnoticed. In any case, the spider can determine whether to inject venom or deliver a "dry bite," as well as how much venom to inject.
  • Question
    Would spray that I use for a hornet's nest work on black widow webs?
    Monty Hansen
    Community Answer
    Yes! I use this all the time, especially the foaming ones, to kill black widows. Wasp spray goes 20 - 30', so you can kill them from a long (safe) distance. Also, the foamy spray sticks to the egg sacs. Don't just spray the web, though; come back at night and kill the spider, otherwise you will just cause it to move to another (perhaps more dangerous) area.
  • Question
    Could a daddy longlegs kill a black widow?

    No, it could not. A black widow's venom is too powerful against a daddy longlegs.
  • Question
    Is it dangerous for cats to try and hunt black widows?
    Community Answer

  • Question
    How can I tell if a black widow spider is male or female?
    Community Answer
    Male black widows do not have the notorious red hourglass, and they also have red spots on their tops.
  • Question
    How do I get rid of false black widows?
    Community Answer
    False black widows are basically harmless, so you can just capture them and take them outside.
  • Question
    Can you die if the bite is left untreated?
    Tina Sorensen
    Community Answer
    Spider bites can cause a huge headache, but the black widow and brown recluse are rarely deadly. They only become critical if left untreated. There is no antivenom for the recluse, but there is one for the widow. The only time venomous spiders can cause critical health issues are for very young children, the elderly or someone with numerous health problems.
  • Question
    What should I do if my clothing is bitten?
    Community Answer
    You don't really need to do anything beyond wash the clothes.
  • Question
    How painful is a .22 round in comparison to the poison of the Black Widow?
    Community Answer
    The .22 round is more painful by pretty much any measure. It causes significantly more tissue and muscle damage.
  • Question
    What should I do if a black widow bites my face and no one can help me?
    Community Answer
    You have plenty of time to get yourself to the hospital.
  • Question
    How many back widow spider sightings qualifies as an infestation?
    Community Answer
    Normally if you see more than 3 within a 30-50 foot radius. You know you have an infestation at that point. Once a mother has its kids, then it’s safe to say it's started.
