| What the guides say | Guide |
|---|---|
| Interior gaps, like the space under a baseboard or an attic hatch, are just travel routes a mouse uses once it's already inside, and sealing those only reroutes the mouse to a new interior path rather than keeping it out. Larger holes need hardware cloth, metal sheeting, or cement rather than mesh alone. | Why Your Mouse Traps Aren't Working: Victor Snap Trap Placement Mistakes (Ontario Guide) |
| A well-known bed bug identification guide for homeowners puts it plainly: while bites might suggest bed bugs, they are not a good method for diagnosing an infestation, because bite reactions are so variable from person to person . Early bed bug activity is usually concentrated close to where someone sleeps or spends long stretches of time, not spread randomly through a whole home. | Bed Bug Bites vs. Other Insect Bites: How to Tell Them Apart |
| The guidance lists the conditions a clinician considers alongside bed bug bites: dermatitis herpetiformis, drug eruptions, ecthyma, other insect bites, pemphigus herpetiformis and scabies. Only a health care provider can tell you what a rash is. | Bed Bug Bites vs Skin Rash in Ontario |
| Many homeowners are convinced they have bed bugs before anything has been checked, because they woke up with bites. Bites on the skin are a poor indicator of a bed bug infestation, because bed bug bites can look like bites from other insects such as mosquitoes or chiggers, rashes such as eczema or fungal infections, or even hives. | How to Tell If You Have Bed Bugs Before Spending Any Money |
