Spiders often make their presence felt in bathrooms, where they have an unfortunate habit of getting trapped. Spiders struggling to get out of the tub can be disconcerting, especially if you have a minor fear of them, but they are rarely a real problem.
Most homes have a few spiders, which lead quiet, unobtrusive lives in corners. They generally keep away from people and you might not even notice them. They don't need large amounts of moisture and are unlikely to be attracted to your bathroom for that reason. However, spiders often fall into baths and sinks and cannot get out, which is the main reason you are most likely to notice spiders in your bathroom.
Spiders are normally useful, because they catch pest insects such as mosquitoes. However, a few species have dangerous bites, especially in tropical areas. If one or more members of your family have a fear of spiders, they may prefer not to see a large spider huddling in the bath. Spiders may also indicate an infestation of more destructive or annoying invertebrates such as flies.
North America is home to approximately 2,500 species of spider and there are at least 40,000 species worldwide. Many of these spiders are difficult to distinguish from one another unless you are an expert. You can have a shot by taking a few photographs of the spider and its web, preferably with an object included for scale. Compare the photographs to those in a guidebook or online guide. Identification forums may connect you with an expert.
To remove a few spiders, simply catch the spiders and put them outside. Place a glass over each spider, slide a sheet of cardboard underneath and carry the arrangement outside. Shake out the spider a short distance from your home. If you do not want to go anywhere near the spider, run a length of toilet paper over the side of the tub or sink and down to the floor. Leave the door open. The spider can climb out and leave by itself. Simply dust or vacuum up any remaining webs. If you see egg sacs, which look a little like cocoons, put them outside. Most spiders are useful creatures to have in your garden. If there are a lot of spiders, you probably need to deal with the cause of the problem, which is most likely an abundant source of prey. Remove potential food sources for flies from your home, keep garbage in outside cans, and ensure your bathroom doesn't become too damp.
