A spider infestation is best handled as a site problem, not just a collection of visible spiders. Remove accessible webs and egg sacs, reduce the insects spiders feed on, clear harbourage, seal practical entry gaps and identify where activity is concentrated. Treatment choice then depends on the spider, building, access and conditions around the property.
For a Rockhampton home with recurring activity, see pest control in Rockhampton and describe where and when spiders are appearing.
Work from the source outward
Start by recording the rooms, exterior walls, sheds, eaves, lights and garden edges where activity repeats. Look for:
- webs returning to the same corners;
- egg sacs in protected gaps;
- insects gathering around exterior lighting;
- stored items against walls;
- vegetation touching the building;
- gaps around doors, screens, pipes and vents.
Vacuuming accessible webs and egg sacs can remove visible material, but it will not correct the conditions supporting new activity. Reduce clutter, move stored items off walls where practical, manage moisture and insect prey, and repair usable gaps.
Avoid handling spiders you cannot identify. If activity is widespread, in difficult voids or involves a spider of concern, ask for species and site advice before choosing a treatment.
