2. Cobweb Spider (Steatoda spp.): These spiders have a round abdomen and build tangled cobwebs in corners and crevices. The black widow and brown widow belong to this group.

3. Jumping Spider (Salticidae): Jumping spiders are small and agile, with the ability to leap significant distances. They have excellent vision and often have vibrant colors.

4. House Spider (Tegenaria domestica): This spider is usually brown or grey and has a herringbone pattern on its abdomen. They build funnel-shaped webs in corners and walls.

8. Regularly Check and Clean Outdoor Structures: Sheds, garages, and other outdoor structures can be attractive to spiders. Regularly inspect and clean these areas to prevent spider infestations.
