Direct Intervention 

In order to really get to them, you need direct impact. We are talking about shoes, newspapers and direct spraying. Anything that you get on to the spider’s body through direct spraying can help you kill them. This is because they groom their bodies using their mouths. It is a particular trait for all arachnids. However, the fact that spiders spend most of their lives on the web means they won’t come in contact with most pesticides. Your best bet is to individually eliminate them through direct contact.
