You may wonder what happens when you kill a pregnant spider. First of all, it can be dangerous. Spiders are a natural pest control agent. But killing them will have other consequences as well. In addition to the obvious dangers, killing a spider will damage your house and contents. Luckily, only a small percent of spider bites result in necrotic lesions. In fact, if you kill a spider, you are destroying the natural habitat of the spiders and its young.

Egg sacs
You’ve probably seen spiders with their egg sacs inside of their body. The sacs are white or cream in color, and some of them have bumps or spikes. Black widow spiders have egg sacs that are about the size of a pencil eraser, and each one contains hundreds of eggs, which are randomly distributed throughout the spider’s web. Unlike other spiders, black widows have no way of identifying their own egg sacs.
Luckily, they aren’t aggressive. When killed, most spiders die after laying their egg sac. These spiders liquefy and their offspring crawl onto the mother. Once you kill the spider, however, the offspring are not likely to survive. So it’s a good idea to take your time when attempting to kill a pregnant spider. Don’t forget to look for signs of pregnancy.
Larger abdomen
Despite what you may have heard, one of the first signs that you’re dealing with a pregnant spider is an enlarged abdomen. The spider’s abdomen will be bloated, and the egg sac is very close by. This bloated abdomen indicates the spider has recently eaten a large meal. When you kill a spider, be sure to check the abdomen for an egg sac. Once you find an egg sac, you’re dealing with a pregnant female.
The egg sac will be laying eggs. This means that when you kill a pregnant spider, it will be laying eggs in its abdomen. If you accidentally kill the spider, it’s likely to break the egg sac and the spiderlings will be born too early. Thankfully, only ten percent of spider bites result in necrotic lesions. Those are still terrible injuries, and you can’t afford to hurt an insect if you kill a spider.
Cannibalistic behavior
Did you know that when you kill a pregnant spider, she will give birth to more than one child? A study has revealed that this behavior is a natural response for female spiders to increase their reproductive output. However, when you kill a female spider, you will be reducing the opportunity for future reproduction. Males usually use a cautious strategy to secure matings. For example, they will prefer to mat with feeding females or moulting females. In addition, sexually cannibalistic spiders often practice coercive mating.
While some people may view this behavior as a sign of a predatory male, it is important to note that male spiders often cannot defend themselves against females that attempt to eat them. Although this behavior is not a sign of weakness, it may be necessary to prevent further mating and reproduction. Many species of female spiders exhibit a cannibalistic behavior. While most species of female spiders will kill one another, male spiders are less likely to do so.
Chances of young spiders surviving without mother
The chances of a spiderling surviving without their mother depend on several factors. Mothers usually stay near their eggs, protecting them from predators. Similarly, eggs laid in a social spider colony have higher survival rates. In addition, the adult spiders in these colonies defend the eggs from predators. Thus, killing a pregnant spider can kill the entire colony, resulting in the loss of their eggs.
Although maternal care is essential for many species, prolonged parental care can lead a female spider to postpone or even forgo reproduction. Spiders like the Stegodyphus lineatus can have only one clutch of young in their lifetime. When the young are hatching, they require the assistance of their mother to emerge from the silk egg-case. The young are helpless when they emerge from the egg sac. The mother feeds the young with liquid food and then rewards her by supplying the empty exoskeleton.
