Entry Points, Moisture and Signs of Activity

Pest Prevention Guides for Homeowners

Understand how pests may enter, what conditions attract them, where activity often begins, and which visible signs may justify closer inspection or professional pest control.

Identify accessible gaps and entry points

Recognize recurring or potentially damaging activity

Remove the Conditions Pests Use

Prevention begins with entry points, moisture, food, and shelter

Pest activity may begin around gaps, damaged screens, utility penetrations, damp materials, stored items, vegetation, standing water, pet food, waste, or hidden spaces that provide shelter.

Use these guides to document where activity appears, reduce accessible attractants, complete safe exclusion and sanitation tasks, and recognize when recurring, destructive, stinging, biting, or widespread activity may require qualified local help.

A Practical Pest Prevention Process

Record the activity, inspect accessible conditions, and reduce attractants

Document where and when activity appears

Record the room or exterior area, time of day, weather, frequency, visible damage, sounds, droppings, nesting material, or other signs.

Review accessible openings and travel paths

Check screens, door gaps, vents, utility penetrations, siding gaps, foundation openings, roof edges, branches, and vegetation contact.

Reduce moisture, food, clutter, and shelter

Address accessible leaks, standing water, open food, waste, dense storage, cardboard, wood piles, overgrown vegetation, and damp areas.

Escalate destructive, hazardous, or recurring activity

Termite damage, aggressive stinging insects, widespread rodents, repeated bites, wildlife entry, contamination, and recurring infestations may require qualified professional help.

Pest Prevention Safety Reminder

Avoid unknown chemicals, aggressive pests, contaminated areas, and unsafe access

Do not disturb active nests, handle wildlife, enter contaminated attics or crawlspaces, mix pesticides, use products outside their labels, or place chemicals where children, pets, food, water, or beneficial wildlife may be exposed.

Leave the area and contact emergency services, animal control, poison control, or qualified local pest professionals when there may be severe allergic reaction, venomous animals, aggressive wildlife, widespread contamination, dangerous pesticide exposure, or another immediate hazard.
