As the old wives tale has it, these are the most dangerous spider with their venom being the most lethal, but their mouths and fangs are too small to bite a human. They are almost transparent, which helps them hide in plain sight. Females are slightly larger than males, growing to 8mm in body length.
Key Differences between Brown Recluse vs House Spider
Of those rare bites the vast majority of bites can be effectively treated with RICE (rest, ice, compression, and elevation) without any dire consequences. Unlike most spider species, brown recluse spiders only have six eyes. They have three pairs of eyes, which differs from most spiders who have eight eyes arranged in two rows of four. A brown recluse spider has a darker patch that is wider near the eyes and narrows like a violin as it moves towards the spider's abdomen.

In many cases, the spider has crawled into a clothing item or a shoe and bites when you put the item on. While commonly spotted near water bodies, they can also be found in damp areas of homes. They’re known for their ability to “walk on water” and hunt aquatic and terrestrial prey. They’re large, dark brown with pale markings, and equipped with water-repellent hairs.
Do house spiders bite, and are their bites dangerous?
Almost all spiders have the ability to bite, but the fangs of most spiders are too small to penetrate human skin. Spider bites, including bites by the brown recluse, cause only a few deaths per year in the U.S., usually in children. In the United States, only two spiders have a medically significant bite. Others, like the yellow sac spider and hobo spider, have been reported as having painful bites, but this isn’t yet proven.

You should seek medical assistance, but most treatment plans involve icing and elevating the bite, with an over-the-counter painkiller usually recommended. Do not continue to self-treat your spider bite wound if it becomes infected or if a boil or ulcer develops. You will need more specialized treatment by a healthcare provider.
Younger spiders or those that have just molted won’t have the violin marking. Between a brown recluse vs. house spider bite, house spiders shouldn’t leave you with any lingering effects. While most spiders are venomous and can cause a reaction, not every arachnid is dangerous enough to make you ill. The brown recluse and black widow spiders are the most venomous species across the states.
Can my doctor test for a brown recluse spider bite?
They are common indoors during January and are completely harmless to humans. Males have orange or yellow towards the carapace that darkens to brown in the front. Females can grow to 20mm in body length and 60mm in leg span with males being smaller.
A house spider has no such pattern and is uniform in color on the cephalothorax. The giant house spider is a dark brown spider with lighter markings on the sternum. There are three light spots on each side, that form an arrow shape that points towards the spider’s head.
It is often seen weaving its webs in corners and crevices of homes. Many people mistake the brown recluse for the house spider because they’re often found hiding in homes, but it’s an important distinction you need to make. The brown recluse bite can be potentially dangerous, so you will need to recognize the spider you have in your room so you can avoid these bites.
Some of the rarer but more lethal effects of the venom of brown recluses include haemolysis and cutaneous and viscerocutaneous symptoms. The females of the species produce a number of egg sacs that they suspend in their webs. The egg sacs are spherical in shape and have tan outer layers with a paperlike texture. To help prevent house spiders from dwelling in your home, ensure that you keep areas clean and free of clutter. Vacuum regularly and seal any cracks or crevices that may act as an entry point for the spiders.
Dark or orange-brown, domestic house spiders have a pale mark on the breastplate. Woodlouse spiders have reddish heads and gray abdomens with robust bodies. They can be found in damp areas under rocks and logs outdoors, in basements, or under floorboards in homes. They specifically prey on woodlice and are not known to be harmful to humans.
The brown recluse spider and the house spider have slight differences in size. The size of the brown recluse spiders typically ranges from 0.24 – 0.79 inches (6 – 20 millimeters) as adults, but some can grow beyond that. The bites of Brown Recluse spiders are of greater concern due to their potential for necrotic reactions, but such severe bites are relatively rare. House Spider bites, on the other hand, are generally harmless and rarely cause serious symptoms. Though both types of spiders spin makeshift webs, they do so in different areas. The location of the web can help you determine the difference between a house spider and a brown recluse.
