To get rid of baby spiders, first you need to identify the source; possible cracks that are around windows, screens, and doors should be sealed where appropriate. Use caulking and other effective mixtures to seal the holes to keep spiders out; just in case you have a garden that is outside the house, try using mulch made from cedar bark. Baby spiders can be swept or scooped up with a vacuum, and the spiders can be killed with a non-staining spray labeled for spider control. You can also mix a little bit of soap and water into a spray bottle and spray possible baby spider locations.

When my sister had her bedroom in a room in the basement, she had lots of creepy crawlers that would "bug" her. She got a room spray "bomb." She had to close the door and not go in for a few hours after releasing the spray. She said it always worked for a while to keep the spiders, etc. away. I'm just not sure how safe it would be to have those fumes lingering afterwards.
Spray the baseboards with tempo ultra. Should be able to purchase at any hardware supply store. Can also spray the outside base of your house and will eliminate all the spiders in ur house. Safe in the house
