Fill cracks along the home foundation
All the cracks along the home foundation should be filled with silicon caulk, while other entry points, like holes in screen doors, are also to be efficiently sealed or fixed. This should help you prevent spiders entering your house. Small pieces of screen are included in the screen-repair kits, which allow you to cut them and fit over the holes. Adhesive, which is used to bond the patch to the screen, is also an integral part of such kits.
Keep your house clean
In order to ensure that spider does not find your house to be an ideal place, it is strongly recommended that you keep it clean. Get rid of the clutter from cardboard boxes, cupboards, stacks of books as well as from the floors in the house. Spiders are likely to hide in and around objects that are spread on the floor.
Once or twice a month, you should be spraying spider insecticide in different parts of your house, especially the outside barrier of the home. Apart from that, you can also lay hedge apples around the house after cutting them up.
Use yellow bulbs
It is a fact that white light attract insects more than yellow lights. Therefore, it is highly recommended that you opt for yellow lights outside your house.
If you have any bushes or vines outside your house, you need to prune them because spiders like to hide there. In a detached shed or garage away from the house, you can store firewood, building supplies and composting material.
