✅ BugOffControl Quick Action Checklist

• Identify where ants are entering (outlet, switch, baseboard gap)

• Turn off the power before opening any outlet cover

• Use gel bait — not spray — inside wall voids

• Apply a non-repellent barrier around entry points

• Seal cracks after activity drops

• ⚠️ Important Safety Tip: Never spray liquid insecticides directly onto wires, outlets, or electrical fixtures. Doing so can create a serious risk of electrical shock, short circuits, or even fire. Instead, stick to ant baits, safe dusts, or sprays specifically labeled for use near electrical equipment, and be sure to seal any cracks or entry points once the ants are gone.

• Monitor for 7–10 days

Why Ants Go Into Wall Outlets and Switch Boxes

Ants don’t eat electricity — but they love the conditions around electrical fixtures.

Here’s what draws them in:

• Warm wiring gives off gentle heat

• Tiny wall gaps give hidden entry

• Condensation creates moisture

• Dead insects collect inside boxes

• Wall voids offer a safe nesting space

• No light and low disturbance

Some species — especially ghost ants, odorous house ants, and pharaoh ants — often nest inside walls and electrical boxes.

So the solution is not just killing visible ants. You must eliminate the colony and block entry.

That’s where the right products matter.

⚠️Caution:

Before you go sticking gel or dust into your walls, keep these “Golden Rules” in mind:

1. Power Down: Always flip the breaker to that room off before removing an outlet cover.

2. Avoid the “Hot” Parts: Never apply gel bait or dust directly onto the brass screw terminals or exposed wires. Apply it to the inside of the plastic wall box or the wall void behind the box.

3. No Liquids: Never use the Ortho Home Defense spray inside the electrical box. Use it only on the baseboards below the outlet.

A Quick Note on the Terro Trap

Terro Non-Toxic Indoor Trap for crickets and spiders. While great for general pests, it is a mechanical trap (sticky). It won’t stop an ant colony living inside a wall because it only catches the “scouts” that happen to walk over it. For an outlet infestation, the Advion Gel is your MVP because it’s a slow-acting poison that kills the whole nest.

 Ortho Home Defense — Best Residual Barrier Spray

This is for perimeter and crack treatment, not direct outlet spraying.

Pros

• Long residual barrier

• Easy trigger wand

• Indoor/outdoor use

• Stops new entry

• Good coverage

Cons

• Repellent formula

• May scatter colonies

• Not for deep voids

Best use: Around baseboards and wall entry points — not inside electrical boxes.

 Use Ortho to stop new ants from entering after baiting.

• Borax-based safer pest control
• Works effectively for months
• Destroys ant colonies within two days
• Targets crickets, spiders, roaches, centipedes

Cons

• Best for small bugs only
• Not ideal for non-sugar ants

Best use: To trap and catch indoor ants

 Harris Diatomaceous Earth — Best Dry Dust Option

A mechanical killer. No chemical poison.

Pros

• Non-toxic grade available

• Good for wall voids

• Long shelf life

• Odorless

• Pet-friendly when used right

Cons

• Slow action

• Must stay dry

• Dusty application

Best use: Light dusting in wall voids with power off.

Pick this if you prefer a low-toxicity control layer.

Pro Tip: Use a “bellows duster” to apply this. If you just dump a pile of dust in there, the ants will simply walk around it. You want a microscopic, invisible film. Also, DE is mechanical (it cuts their shells); it takes a long time to work compared to chemical dusts like Alpine WSG

⚠️ Safety Rules When Treating Outlets

Always follow these steps:

• Turn off the breaker first

• Never spray liquid into live outlets

• Use gel or dust instead

• Apply outside the box, not on the wires

• Replace the cover securely

• Follow label directions

How to Stop Ants in Outlets — Correct Order

First, place bait.
Then, wait for feeding.
Next, reduce activity.
After that, seal cracks.
Finally, apply barrier spray outside.

Transition steps matter. If you spray first, ants may split colonies.
