A perimeter spray treats only the places and pests listed on its label. It is not a substitute for cleaning, fixing leaks, and sealing entry points.
Why it matters: Spraying the wrong area or dose can expose people, pets, wildlife, or food without solving the pest problem.

Understand the job before starting
The label defines permitted locations and application instructions for the specific product.
A common mistake to avoid
A dilution or site used for another product may not be allowed here.
Use what you already have. Check each item when it is ready.
Before you begin
Do not spray as a routine habit without a pest need. Do not spray people, pets, food surfaces, bowls, toys, electrical equipment, drains, or water. An indoor label does not make every indoor surface appropriate.

STEP 1 OF 5
Match the exact bottle
Start here: Match the exact bottle
Illustration: Read the pesticide label. Read the steps for your exact task.
Read-aloud is available in supported browsers; the written steps always remain available.
Find the product name, formulation, and EPA registration number.
Ortho Home Defense has multiple products and applicators.
Read the complete label on your container, not an instruction for a similar-looking bottle.
Before moving to the next step
Check this specific result: I have the instructions for my exact product.
If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.

If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.
STEP 2 OF 5
Check the treatment area and weather
Start here: Check the label and weather.
Example: Check the label and weather. Follow the written step.
Identify the pest and allowed sites.
Read wind, rain, runoff, and temperature limits.
Move pets, people, food items, and toys away.
Wear the listed protection.
Keep children and pets from accessing the sprayer and wet surfaces.
Before moving to the next step
Check this specific result: The site, weather, and protection meet the label.
If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.
STEP 3 OF 5
Set the wand by the label
Start here: Set up exactly as labeled.
Example: Set up exactly as labeled. Follow the written step.
For the specifically linked Ortho Home Defense Insect Killer for Indoor & Perimeter2 directions, the nozzle is held about 12 inches from the surface.
Other products can differ.
The label also defines the treatment band and amount.
Measure the nozzle-to-surface distance; it is not the distance your feet stand from the house.
Before moving to the next step
Check this specific result: My nozzle distance and treatment band match this label.
If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.
STEP 4 OF 5
Apply only the directed amount
Start here: Use only the directed amount.
Example: Use only the directed amount. Follow the written step.
Point away from your body and treat only allowed locations, avoiding drift and runoff.
Do not drench the soil or make a wider band “for extra protection.” Stop for a leak or changing weather.
Keep the wand away from eyes and skin.
Before moving to the next step
Check this specific result: I used only the listed application pattern and amount.
If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.
STEP 5 OF 5
Let the area become safe before return
Start here: Wait until re-entry is allowed.
Example: Wait until re-entry is allowed. Follow the written step.
Follow the container’s reentry instructions; the linked formulation requires spray to dry before people/pets return. “Dry” is not a guarantee the chemical is harmless if licked or eaten.
Store the sprayer safely, wash as directed, and record the application.
Before moving to the next step
Check this specific result: I followed reentry, cleanup, and storage instructions.
If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.

How to use the video with this guide
Read “Before you begin” first. Watch the relevant part, pause, then return to the written step and its completion check. Use captions and playback speed if they help. A demonstration may cover only part of the task or show different equipment.
Your model’s instructions and current official guidance take priority. For urgent problems, follow the stop instructions without waiting to watch a video.
For this guide, the final result is: I followed reentry, cleanup, and storage instructions.
A concrete way to approach this task
Read the exact product label and confirm the site, application instructions, and access restrictions that apply to your situation.
What if I cannot complete a step?
If the label does not permit the intended use, do not improvise a dilution or location. Choose an approved method or ask for help.
Identify the exact step: “Match the exact bottle.” Record what you tried, what happened, and which item or model you used. Ask for help with that specific problem rather than repeating an unsafe or unsuccessful action.
Do not spray as a routine habit without a pest need. Do not spray people, pets, food surfaces, bowls, toys, electrical equipment, drains, or water. An indoor label does not make every indoor surface appropriate.
Connect this skill to everyday life
Write down the total move-in cash and monthly costs before applying. Ask which charges are required and which are optional.
Advertised rent is not necessarily the whole monthly cost. A refundable deposit still needs cash now. An application does not mean you have a signed lease.
