Photo confirmation checklist
Use these visual checks to compare the pest, the evidence, and the likely source area before choosing a treatment path.
Quick answer
What to know first
Spider prevention is mostly habitat and prey control. Spiders follow insects and sheltered hiding areas, so reducing webs, clutter, and entry points lowers indoor encounters.
Check first
- Webs in corners, garages, sheds, or crawl spaces
- Egg sacs near undisturbed storage areas
- Spiders appearing near lights or insect activity
Avoid this
- Applying pesticides before identifying the pest or evidence
- Treating one symptom while moisture, food, or entry sources remain
- Skipping monitoring after the first cleanup or treatment
