Black widow spiders are infamous for their shiny black bodies and red hourglass marking on the underside of their abdomens. Their name comes from the widespread misbelief that female black widow spiders eat the male black widow spiders immediately after mating, although this rarely occurs in actuality.

如何摆脱家里的黑寡妇
因此，您在家中发现了一只黑寡妇蜘蛛。不幸的是，在您家中找到其中一个有毒的蜘蛛可能意味着您附近还有更多。一只女性黑寡妇蜘蛛可以在短时间内产生数百个后代，从而导致您的房屋大量侵扰。
尝试以下步骤，以帮助摆脱家中的黑寡妇蜘蛛：
- Declutter your home.黑寡妇蜘蛛喜欢藏在房屋的混乱区域中，例如地下室，一堆盒子，混乱的壁橱，阁楼，车库，储藏区等。花时间通过摆脱您不再需要的东西并清理这些区域来仔细整理这些区域，以便没有可能吸引昆虫的食物来吸引黑人寡妇蜘蛛。确保在此过程中戴上手套，长袖和裤子，以防您在移动盒子时遇到任何蜘蛛。
- 检查房屋的外观是否有裂缝和缝隙。黑寡妇蜘蛛会发现different entry pointsinto your homes, such as open windows, holes in your door’s screen, and cracks in your home’s exterior. Do a thorough examination of your home for any gaps or holes that pests may be entering your home through. Then, replace any torn door or window screens and repair holes with a sealant or caulking product to prevent pests from entering.
- 彻底给您的房屋灰尘。If you notice spiders coming out of or hanging around electrical outlets or vent areas, use a duster to clean this area up. Then, replace the plate cover or vent cover to prevent spiders from using this to enter your home.
- Spray spiders with an aerosol spray.There are a variety of pest-killing aerosol sprays on the market that allow you to kill spiders and other pests with the spray directly. Keep a bottle of this on hand for any black widows you spot.
- 销毁蜘蛛网。网络构建蜘蛛，像黑寡妇一样，依靠他们的网捕获食物。如果您不断地用扫帚粉尘并摧毁他们的蜘蛛网，则可以防止蜘蛛抓住下一顿饭，这最终将把它们赶出藏身之处并离开家。
- Make a DIY天然蜘蛛驱虫剂。Like many pests, black widow spiders do not care for many essential oils, including peppermint, tea tree, eucalyptus, citronella, and lavender oil. To make a DIY repellent, add a couple of drops of one of these essential oils to a spray bottle filled with water and a few drops of dish soap, making the mixture stickier. Then apply this to common spider hiding places in your home, such as near baseboards, window sills, closets, garages, and more.
- 施用蜘蛛杀虫剂。购买杀虫剂治疗以杀死蜘蛛，并将其彻底应用于您家中的普通蜘蛛区域。始终确保密切按照您使用的任何农药的指示，并仔细检查一下，如果您在家中有任何宠物或孩子，则可以安全地使用它。
- 安装门扫。门清扫防止蜘蛛和其他害虫进入您的房屋，并且可以很好地帮助黑寡妇蜘蛛控制。
- 彻底清洁您的房屋。通过用真空吸尘器清洁房屋，摆脱房屋中的黑寡妇蜘蛛。真空吸尘器可以是吸收鸡蛋囊，蜘蛛，昆虫和食物碎屑的有效工具，这些工具可能吸引昆虫，即黑寡妇的食物来源。完成真空后，立即在外面清空真空吸尘器and take the trash off your property to prevent spiders from hatching on your property.
- Set out spider traps.蜘蛛陷阱通常是通过在粘性表面捕获黑寡妇来工作的胶水板。一旦被捕获，蜘蛛就无法释放自己，并且可以轻松地处置。
如何将黑寡妇拒之门外
蜘蛛可以是有益的害虫，因为它们吃了其他更具破坏性的害虫，例如蚊子，甲虫和蚂蚁。但是，如果您在院子里发现黑寡妇蜘蛛，我们建议立即采取行动，因为这些有毒的蜘蛛可能会决定最终在您的家中避难，这给您和您的亲人带来了危险。
Here are our top tips for keeping black widows out of your yard:
- Eliminate other pest problems immediately.Black widows are web-building spiders that need insects nearby for their webs to catch. If you don’t have an insect problem in your yard, your chances of having a huge black widow problem are reduced. So, make sure that you immediately take care of any other insect problems in your yard, such as ants, mosquitoes, roaches, or caterpillars, which are all the preferred food sources of black widow spiders.
- 清除碎屑和柴火。黑色蜘蛛以建立网站并藏在碎片和木柴中藏匿而臭名昭著。从您的财产中删除这些结构。如果您必须保留它们，请将它们移离房屋的周长，以防止蜘蛛轻松从柴火堆中移动到您的房屋。确保在此过程中始终戴上手套。
- Apply a concentrate around the perimeter of your home.购买并应用spider liquid residual concentratearound the foundation perimeter of your home. Take time to apply this carefully around your perimeter, including near window sills, door frames, vent openings, garages, deck areas, and more. This will make it difficult for spiders to breach your home.
- 定期维护院子。Black widow spiders, along with many other pests, are attracted to overgrown yards, ledges,高草和植被, which can provide them with easy access to your home. Make sure that you regularly mow your lawn and trim plants to keep this risk minimized.
- 更换灯泡。许多昆虫被灯泡吸引。如果您的灯光，尤其是在露台或甲板上，请确保仅在必要时才能打开它们。另外，考虑将灯泡更改为钠蒸气或黄色灯泡品种。这些灯泡对昆虫的吸引力较小，昆虫会阻止昆虫在您家附近聚集，从而减少了您家中和院子附近的黑寡妇蜘蛛的食物。
- Attract natural predators to your yard.Birds,such as wrens，喜欢吃黑寡妇蜘蛛。设置巢箱和水基础，以吸引鸟类进入您的院子，它们会在您的蜘蛛问题上吃掉。但是，请记住，这可能适得其反，并引起不同的野生动植物害虫问题。

如何识别黑寡妇
黑寡妇是独特的蜘蛛，其腹部上有所有黑体和红色或橙色的标记。女性黑寡妇蜘蛛具有“典型”的黑寡妇外观，我们的腹部具有全黑，闪亮的身体和独特的红色沙漏形状。雄性黑寡妇蜘蛛的比女性小。此外，雄性黑寡妇蜘蛛不会咬人，而且比女性的攻击性要少得多，因为它们没有强烈保护卵。雄性黑寡妇的腿也将成比例地占据一半的腿，而女性黑寡妇蜘蛛的外观则更为比例。
雄性和女性成年黑寡妇蜘蛛都有八只腿，八只眼睛，一个圆形的身体，范围从三到10毫米，尽管女性有时可能长到13毫米长。
黑寡妇鸡蛋囊是球形的，颜色为白色至灰色。它们通常在里面包含一到两百个奶油或黄色鸡蛋，最终将孵化成婴儿蜘蛛。大多数女性黑寡妇蜘蛛会立即产生许多卵囊，因此，如果您发现一个鸡蛋囊，您可能已经被大量感染或在蜘蛛侵扰的边缘处。如果您找到鸡蛋囊，请立即致电当地的害虫防治专业人员，因为它们会尽快孵化，使数百个黑寡妇蜘蛛自由漫游您的财产。年轻的黑寡妇蜘蛛是白色和橙色，但随着年龄的增长会变成黑色。像成人黑人寡妇蜘蛛一样，他们的身体上将有一个或两个红色的三角形，可能类似于沙漏形状。
Like most网络构建蜘蛛，黑色寡妇蜘蛛居住在其网上或附近，它们通常在门口，木柴堆，高大的草和地面上建造。这些位置使他们可以轻松地进入他们喜欢的食物来源，这些食物通常是昆虫，例如蚂蚁，蟑螂，蚱hoppers和果蝇。总体而言，黑寡妇蜘蛛是孤独的蜘蛛，将生活在凌乱，不规则的网络附近的黑暗，低活动区域。您可能会发现黑色寡妇蜘蛛的典型区域包括房屋的外观，地下室，壁橱，混乱的空间，黑角，车库，木桩等。
