Spiders are very useful at reducing the number of pests that plague humans. But most people don't want spiders inside their homes. When spiders infest a house, they can breed out of control, especially when there is plenty of food available. Unfortunately, in Australia, several poisonous species of spiders often invade homes.

If you have a spider infestation in your home, you'll probably see the following signs.

1. Webs

The most obvious sign of a spider infestation is webbing. And not all webs will be high up. For instance, funnel web spiders often build their webs close to the ground, near moisture and darkness. If you have found webs in your attic or in a rarely used room, close to the ground, you could have a funnel-web spider infestation.

2. Wandering spiders

Female spiders usually remain in their webs. But male spiders go in search of females at certain times of the year, especially in late summer and early autumn. If you are seeing a lot of wandering spiders in your home, they could be male spiders entering your home to mate with females nesting somewhere inside your home.

3. Mysterious bites

One or two occasional bites may just be a coincidence. But if you or other people in your household keep being bitten by something, this could indicate that spiders are wandering around in your home.

4. Egg sacs

If you have noticed a lot of white, webby sacs throughout your home, in corners or under shelves, these could be spider egg sacs. If spiders are breeding in your home, that means the conditions are ripe for spider infestation.

5. Spider droppings

Spider droppings look like dark stains, and you can mistake them for dirt or old paint. Wherever you find these droppings, spiders are feasting on their prey. You may find nests above the spots where you find the droppings.

6. Lots of dark nooks and crannies

Spiders like to nest in dark nooks and crannies. So, if you have seen other signs of spiders in your home and your home has an abundance of cracks and holes where spiders can hang out, you may have a spider infestation.

7. An abundance of other pests

Spiders gravitate to areas that are rich in food, namely insects. So, if your home has a problem with pests such as flies, ants, and cockroaches, spiders may be nesting in your home, ready to take advantage of the rich food source.
