What Eats Spiders In Houses?

Here’s Why You Should Never Kill A Spider

Even though spiders are creepy crawlers that you probably despise, killing them could actually do your house more harm than good. Here’s why.

Besides having long legs and a creepy demeanor, most people are scared of spiders for one specific reason: Their bite. If you’re not sure the type of spider, there’s always a chance that the spider could be venomous. However, it has been proven that only about 10 percent of spider bites lead to necrotic skin lesions. These types of bites actually don’t come from the innocent brown spiders that make a home within your home. In fact, it’s actually quite difficult for a spider like that to bite you.

So if that’s the case, why in the world are we so drawn to killing spiders? If anything, spiders can actually help our homes instead of harming them. Since spiders are naturally predators, they capture pests within your home.

If you’re not one to welcome spiders into your house, learn how to keep them out without killing them in this video:

Now these household pests aren’t just flies, which can be a common misconception. Spiders even prey after disease-carrying insects. They go for those nasty indoor pests such as cockroaches, mosquitos, earwigs, and even clothing moths. The more you keep daddy long-legs around, the less mosquitos you’ll have floating around your home.

Typical household spider species will include cellar spiders (pholcidae, also known as “daddy long-legs”), cobweb spiders (parasteatoda tepidariorioum) and brown reclues (loxosceles reclusa). These spiders will create webs where their food source is coming from. So if you see a spider on its web, it’s even more of an inclination to leave that spider alone. They set up camp based on where the bugs are, so they will be getting rid of those bugs for you!

Don’t kill the spider

Obviously, it isn’t pleasant letting spiders roam around your home. If you cannot stand having a spider in the home, don’t squish it to bits. Instead, capture it with a jar and release it outside. It will find somewhere else to go and will continue preying on the bugs you also despise.

Spiders aren’t the only household creatures you want to keep around. Ever see those crazy looking house centipedes? They also have a huge impact to your home! Here’s why you should never kill a house centipede.

9 Natural Predators That Control Spiders

Pest control isn’t always conducted by people and it doesn’t need to include chemicals. Sometimes nature has its own system of control. For example, the nine critters listed below all prey on spiders. That’s good news for the millions of people around the world who are afraid of spiders. That fear—known as arachnophobia—is so common, that it is considered to be one of the top 10 phobias around the world.

As with most phobias, it doesn’t really help most sufferers to know that nearly all spiders are harmless, or that they themselves are predators for any number of nuisance insects, from buzzing house flies to aphids and beetles that feast on your garden plants. If you have a fear of spiders, it is hard to change your feeling about these eight-legged creatures. So pest control readers who are not only squeamish but positively fearful about even the smallest of spiders will be pleased to know that nature has its own way of handling them.

Spider Predators

In no particular order, the top spider predators include:

  • Lizards. Geckos and chameleons are common lizards of the southern U.S. that feed on spiders as well as other small insects. A study by scientists from the University of California showed that lizards are so voracious when it comes to spiders that they can eradicate them in controlled environments. When scientists introduced lizards to several of the Bahama Islands to attempt to control orb spiders, an invasive, non-native species, within five years the spiders were eradicated on all islands where the lizards were present.
  • Fish. Trout, archers, and mosquito fish (despite their name) are among those that feed on spiders. Of course, the spider must be or live in or around the water for the fish to have access, but there are several species, such as the water spider, that do just that.
  • Birds. It comes as no surprise that birds are a significant threat to spiders of virtually all kinds (except perhaps the extremely large spiders, such as tarantulas). In fact, some of the most common birds of the U.S., such as robins and wrens, routinely make meals out of spiders. But small birds that prey on spiders also have to be careful that they don’t get caught in the sticky webs—although the spiders rarely eat birds they snare. A garden that is full of song birds rarely has problems with spiders, and even domestic birds kept indoors have been known to feed on spiders if they are given free flight opportunities.
  • Tarantula hawks. This is actually a wasp, not a bird, but the tarantula hawk does hunt down tarantulas in their burrows. The wasp «knocks» on the spider’s web to attract attention, then, when the tarantula appears, it paralyzes the spider with a sting and drags the tarantula to its own burrow to feed to its young.
  • Spider wasps. The larger family of insects to which the tarantula wasp belongs are the spider wasps. The females of each species sting and paralyze the spiders for feeding to their young, but each has a different way of getting the spider to its nest. Some carry the spider, some drag it, some pull it across the water, and others fly with it. But regardless of the method of transport, the end result is the same: fewer spiders for you to deal with.
  • Monkeys. Though it may not be the most practical of matters to keep a monkey in your home to keep spider populations down, there are a number of species of monkeys that do enjoy a bite or two of spider at meal time.
  • Centipedes. Although they are often considered even more repulsive than the spiders themselves, this many-legged arthropod can actually be a control against spiders in your home, Centipedes are carnivorous and use their claws to paralyze spiders and other small creatures.
  • Scorpions. Although they rarely attack humans except in self-defense, scorpions generally create as much—or more—fear for humans than do spiders. But if you are arachnophobic, you may still prefer the slight threat of an accidental scorpion sting to the panic-inducing sight of a spider.
  • Other spiders. Some spiders feed on their own kind—preying on and eating other spiders. This can actually be beneficial to humans because it is often the non-threatening spiders that feed on those that can be dangerous to humans. For example, the innocuous daddy long leg spider feeds on both the hobo spider and black widow spider.

Information Is the Antidote to Fear

Most phobias are by definition irrational, but if you’re the type willing to fight against your fear, you might want to spend some time learning to identify spiders that are truly dangerous and work at tolerating, or even welcoming, those spiders that provide helpful services, such as eating garden pests and houseflies. In the U.S., the small handful of spiders that have problematic bites include:

  • Widow spiders. The black widow (northern, southern, and western varieties) are the most well-known of these famous poisonous species, but there are also brown widow and red widow spiders you should be aware of. All the widow spiders are dark brown or shiny black with red hour-glass shaped markings on the abdomen of the female spider (only females have a dangerous bite). Although this is the most poisonous of North American spiders, its danger is vastly overrated. There are only about 12 bites each year that are rated as serious, and it has been more than 100 years since any human died of a widow spider bite. The vast majority of bites are «dry,» in which no venom is injected. When threatened, the spider usually plays dead or flees. Most bites that occur are accidental, such as when the spider is pinched between skin and clothing.
  • Recluse spiders. The second-most famous venomous spider in the U.S. is the recluse. The brown recluse is the species most people know about, but there are at least 12 others recluse spiders, several of which are also found in North America. These small spiders can often be identified by a violin-shaped marking on the back, although many other spiders have similar markings. Recluse spiders prefer warmer climates and are found from the southern Midwest to Georgia in the east and Colorado in the West. There is some concern that global climate change is now extending the range of this spider. The recluse, as the name suggests, is a shy spider that often cohabits in human dwellings with no problems ever reported. It feeds on small prey and prefers scavenging to active hunting. When bites to humans occur, it is usually because a spider has become trapped in clothing, such as when workers are performing maintenance operations in attics or crawl spaces. Most bites may go unnoticed, but very rarely they can cause open-sore bacterial infections that may take weeks to heal and may leave a scar. Deaths from recluse bites are almost unknown.
  • Hobo spiders (also known as the aggressive house spider or funnel web spider). The hobo spider is generally considered non-toxic by most experts, but it can be aggressive and bite when its egg sacs are threatened. Except in this situation, the spider rarely bites. Reports of toxicity are now attributed to bacterial infections that sometimes occur if the bite site is not properly cared for—a problem that can occur with any insect bite.
  • Yellow sac spiders. The yellow sac, too, is a non-venomous spider, but one whose bite can sometimes result in an open sore that may become infected. It is a small pale-colored spider with a yellow or beige abdomen.

Out of thousands of spider species, this small handful of spiders are the only ones that offer any danger, and even here, the reputation far exceeds the actual danger. Before taking efforts to kill any spider you see, you might want to learn a bit about what creature you have spotted and what benefits it might be performing in your house or garden.


What Attracts Spiders to Your House

The things that attract spiders are too many. We are frequently being asked if spiders are attracted to light or dark but the list of things that may cause spider infestation is very long.

So, what is so tempting that attracts spiders namely to your house? Spiders are like any other creature, they need food and shelter. Many species have adapted to the environment indoors. One thing that draws spiders in your home is a plentiful supply of food. The eight­-legged predators feast upon insects, either by catching them in nets, hunting or ambushing them. That being said, spiders are excellent pest controllers themselves and often used in biological pest control when it comes to crops and gardens. So an effective way to keep spiders at bay is to cut their food supply. In other words, you better lay waste upon any insects that dare to roam your household. Or if your aim is to attract spiders, invite some flies in and they’ll soon join the party.

  1. Spiders are arachnids, not insects;
  2. Wherever insects are abundant – spiders are too;
  3. There are as many as 200.000 different spider species in total. In Europe there are more than 4500 different spider species.
  4. The majority of spiders are poisonous, but most of them can’t pierce human skin;
  5. All spiders can produce silk;

What Attracts Spiders in the House?

Spiders are mainly attracted to the insects in your home, which are their primary food source. But what other factors make them crawl into your house or flat and become your “roommates”?

  • Insects a.k.a Food – their food choices make them nature’s best domestic pest controllers, as they feed on insects. Anything from drain flies through crickets and mosquitoes to fruit flies, cockroaches, earwigs or clothes moths is part of their menu; See what are the most common insects spiders feed on to see what to keep away from your home.
  • Warmth is very attractive to spiders – during cold months spiders seek shelter;
  • Water – some spiders don’t even require water. But if there are any which do, they’d prefer to drink water from sink taps or bathtubs. Yet, just to be on the safe side avoid leaving any sources;
  • Privacy – for this reason you won’t see them in highly visible spots. Where do spiders hide in rooms? They prefer corners, crevices, dark and less used spaces;
  • Second hand furniture – not that it attracts spiders per say, it’s just highly possible to bring a spider egg sac with it;
  • Spider Glue Traps – If you wish to lure the small impostors yourself, try spider traps. They contain pheromones that attract spiders. Once they get their eight legs on the “perfumed” surface it gets them stuck in the trap and eventually die. If your aim is to keep them alive you should be careful on how you use these;
  • Mating drums – Spiders attract one of their own when mating. In fact, spiders have sound rituals which they do, this means even more spiders will be attracted inside your home when the arachnids mate.
  • Domestic waste draws spiders’ natural pray inside your home. To minimize the chance of being infested by the arthropods, simply take care of the household rubbish.
  • Cannibalism among spiders also occurs. Spider species such as the daddy long legs spider would eat not just insects but 8-legged creatures too, so leaving spiders at home as a natural form of pest control, doesn’t mean fewer spiders.
  • Fruits also attract spiders. It’s highly possible to spot a spider crawling out of a banana or grape and the worst thing is that usually venomous spiders hide inside fruits. Always take a close look at what you put in the shopping bag.

In conclusion, what mainly attracts spiders to your bedroom is insects they feed off. Your home provides many different hiding spots for spiders. Despite recent reports, it’s very rare for spiders in the UK to be dangerous to humans. On the whole, they’re more of a benefit as they eat other insects that do pose a threat to human health. But if you really don’t like them, it is fairly easy to reduce their numbers in your home – either follow our simple tips or give us a call and we’ll take care of the problem for you.

The Favourite Hangout Spots of Spiders

It’s a common myth that spiders migrate inside your home once it gets chilly. Household spiders are adjusted to living indoors and tend to prefer dark, narrow spaces with less to none human activity, as they are very sensitive to movement. They lead quiet lives and love their privacy. Spiders don’t necessarily love a damp environment, it’s just the ideal setting for an abundance of insects, hence spider food. Some of them prefer damp conditions while others linger to dry environments.

But where do spiders live in your house exactly:

  • basements;
  • cellars and attics;
  • closets;
  • corners of the ceiling;
  • behind larger household appliances and indoor furniture;
  • in bathrooms;
  • in the garage;
  • inside vehicles;
  • in food, mostly fruits;
  • swimming pools;

You will be surprised to learn that ordinary insecticides aren’t all that effective against spiders.So what on Earth kills spiders? If you have to use a chemical to kill spiders, choose one especially formulated for the job. Panther Pest Control can help you find safe chemical solutions to this type of problem if needed.

Are Spiders Attracted to Human or Pet Food?

No, not at all. Spiders can’t digest human or pet food, so it wouldn’t even cross their minds to try. They prefer domestic pests like cockroaches, earwigs or clothes moths and other.

What Attracts Spiders To Humans?

The might not even know you exist until you become a threat to them. Spiders are not attracted to humans per say, rather they might be attracted to the warmth we emit. Or as in most cases, they just accidentally end up on us coming from the ceiling or anywhere above head height where they’ve spun their webs. How does that happen? A curious spider-related fact is they don’t put all their energy into producing brand new silk every time. They recycle their silk by eating it. So, no, they didn’t want to attack you or take a walk along your body. You just interrupted their recycling process and their silk got “glued” on you when you were passing by.

How to Spider-Proof Your Home?

There are a few things you can do in order to spider-proof your home and prevent the eight-legged rascals from invading your home and get all cosy in the ceiling corners of every room.

  1. Frequent dusting;
  2. Vacuum cleaning holes and crevices;
  3. Removing webs from corners, ceilings and other likely places;
  4. Clean second-hand furniture prior to bringing it into your house;
  5. Sealing tiny crevices and holes- This will close the entrances to your home and, so the little pests won’t be able to get in the house;

Regular cleaning will do much to keep their numbers down. Cleaning and removing their webs will also get rid of their eggs. If you live in a modern home, it may be perfectly practical to seal every tiny crevice and hole. In an older home, this may be more difficult, if not impossible. If you buy second-hand furniture and there happens to be a spider egg sac in it before you know where you are you’ve increased the spider population of your home by several hundred. This is a very strong argument in favour of making sure that if you do buy second-hand furniture, you have to clean it or get it professionally cleaned meticulously. If at all possible, do this before you bring the item into the house. If none of these tips works for you and you still struggle with a spider infestation in your home, don’t hesitate to contact us for efficient spider pest control.
