Answer 3

You really don't need to kill the spiders or destroy the eggs.

Just scrap the egg sack with a hard sheet of paper or cardboard and place it outside of the house preferably near a wall.

Spiders pose no real threat to us. In fact, you can appreciate spiders for their significant contribution to insect control.

Spiders play an important role in controlling insect populations. An arachnologist (a person who studies spiders) in the United Kingdom once calculated that the weight of insects eaten by spiders in that country every year exceeded the weight of the people who live in the U.K.

Preventing Spider Problems

There are many ways to make your home less appealing to spiders. If there are cracks in your foundation or around windows and doors, seal them up.

Check places where water pipes and electrical lines enter your house, and caulk any openings.

Keep woodpiles and debris away from your house.

In storage areas, put boxes up off the floor and away from walls. Seal boxes with tape to keep spiders from living inside them. In general, cleaning up clutter will mean you have fewer spiders.

Pruning vegetation away from your house and keeping the area next to the foundation clear will also make your house less attractive to spiders.

Outdoor lighting sometimes attracts insects, which in turn attracts spiders. You can move outdoor lighting away from windows and doors if this is a problem around your home.

Removing Spiders

You can remove a spider from inside your house by putting a jar over it. Then slip a piece of paper under the jar so that the opening is sealed, pick up the jar, and take the spider outside.

A broom is also a useful tool for moving a spider outside.

Chemicals Are Ineffective

Using a pesticide is not a good solution to spider problems. "Insecticides will not provide long-term control" of spiders, according to the University of California, "and should not generally be used against spiders outdoors." Inside, "control by spraying is only temporary unless accompanied by housekeeping."

Washington State University Extension has a similar perspective: "Most spider problems can be solved without the use of chemicals."

You can also use Spider and Insect Catch and Release Tool -

Answer 4

i think everyone is over-thinking this.  snatch the egg sac up in some tupperware and put it in the freezer, kills every single one. (i had a black widow that put out 17 egg sacs, i never saw one of her spiderlings)

but if it's a larger spider on a web then it is most likely beneficial more than it is harmful. ONE orb-weaver spider kept around for a year can kill around 100 insects. (and mosquitoes could be considered one of the most harmful bugs, these spiders kill tons of mosquitoes) Plus, usually those kinds of spiders balloon out (hang on the end of a piece of web and let the wind carry them off) so they wouldn't stay close to that web at all.

Answer 5

Raid

Answer 6

I mix dish soap and water in a spray bottle(or use Windex if you want) and soak the egg sacks thoroughly.  Let it set for 5 min and wash it off the window with a hose.
