Waseem Jalal

Living in a historic home in Keller or a charming bungalow in Fort Worth has its undeniable appeal. But with that vintage charm often comes the not-so-charming presence of unwanted guests – pests. Whether it’s ants on the march, spiders in the attic, or rodents seeking warmth, keeping these critters at bay becomes a top priority. However, for homeowners with houses boasting original electrical wiring and fixtures, pest control Keller TX takes on an extra layer of complexity.

Here’s why:

  • Chewing Hazards: Rodents, in particular, have a notorious reputation for gnawing on anything in their path. This includes electrical wires, which can cause short circuits, fires, and even power outages. Damaged wires can also expose live currents, creating a serious electrical shock hazard.
  • Nest Nuisances: Squirrels, birds, and even some insects can build nests around electrical components. This nesting material can trap heat, leading to overheating and potential fires. Additionally, nests can block vents and disrupt proper electrical flow.
  • Sticky Situations: Spiders and other web-spinning insects can create webs that can tangle around wires and transformers. This can not only hinder electrical performance but also pose a fire risk if the webs come into contact with sparks.

So, how do you effectively address pest problems in your historic home without compromising the safety and integrity of your electrical system? 

Step 1: Assess the Situation

Before embarking on any pest control measures, it’s crucial to understand the extent of the problem. Here’s what you need to do:

Inspect for Signs of Pests: Look for droppings, gnaw marks, spider webs, or unusual activity around electrical outlets and fixtures. Pay close attention to attics, basements, crawlspaces, and behind appliances – prime nesting spots for many pests.

Identify the Culprit: Determining the type of pest is essential for choosing the most effective and targeted control method. Look for distinguishing features or consult a professional pest control company for assistance.

Evaluate Electrical System: While you can conduct a basic visual inspection for visible damage to wires or exposed components, it’s highly recommended to consult a licensed electrician. They can assess the overall condition of your electrical system and identify any potential hazards created by pests.

Step 2: Prioritize Safety

Once you’ve identified the pest and assessed your electrical system, safety becomes paramount. Here are some key steps:

Address Electrical Issues Immediately: If your electrician finds any damage to wires, exposed components, or potential fire risks due to pest activity, prioritize repairs before proceeding with pest control. This ensures a safer environment while tackling the pest problem.

Turn Off Power: When setting traps or using baits near electrical components, turn off the power to that specific circuit at the breaker box. This minimizes the risk of electrical shock if a pest comes into contact with both the trap and a live wire.

Consider Alternatives: If placing traps or baits near electrical areas is unavoidable, explore alternative pest control methods for those specific locations. Consult a pest control professional for safe and effective solutions.

Step 3: Choose the Right Pest Control Method

With safety at the forefront, here are some pest control Fort Worth TX methods suitable for homes with old electrical systems:

Exclusion: Sealing entry points around pipes, windows, and doors is a crucial first step. Utilize caulk, weather stripping, and mesh screens to keep pests from entering your home altogether. This reduces the need for traps or baits near electrical areas.

Traps and Baits: For targeted pest control, traps and baits can be highly effective. However, be strategic in their placement. Avoid placing them directly on electrical fixtures or outlets. Opt for tamper-proof bait stations or snap traps that can be positioned away from electrical components but remain accessible to the target pests.

Natural Repellents: Essential oils like peppermint, citronella, and cedarwood can be effective deterrents for some pests. However, their effectiveness can vary, and some electrical components might be sensitive to these oils. Consult with a pest control professional or hardware store employee to ensure compatibility before using.

Professional Pest Control: For infestations or stubborn pests, a licensed pest control company is your best bet. They have the expertise and necessary equipment to safely and effectively address the problem while offering peace of mind regarding electrical safety.

Pro Tip for Keller and Fort Worth Residents:

Both cities have vibrant historical societies and preservation organizations. Consult them for resources specific to maintaining the electrical systems in older homes while addressing pest control needs.

Step 4: Ongoing Maintenance

Once you’ve successfully addressed the initial pest problem, don’t let your guard down. Here are some steps to keep your home pest-free and your electrical system safe:

Regular Inspections: Conduct regular visual inspections of your home, focusing on potential entry points, attics, basements, and crawl spaces. Look for signs of pest activity such as droppings, gnaw marks, or new webs.

Seal It Up: Regularly inspect and reseal any cracks, gaps, or openings around pipes, windows, doors, and foundations. This will deter future pest invasions.

Maintain Cleanliness: Keep your home clean and free of clutter, especially in areas like kitchens and pantries. This eliminates potential food sources that attract pests.

Store Food Properly: Store food in airtight containers and avoid leaving crumbs or spills on countertops. Regularly clean up spills and dispose of garbage promptly.

Address Moisture Issues: Moisture attracts many pests. Fix leaky faucets, pipes, and any areas with moisture buildup. Ensure proper ventilation in attics, basements, and crawlspaces to prevent dampness.

Maintain Open Communication with Your Electrician: Schedule regular electrical inspections, especially if you suspect pest activity around electrical components.


Living in a charming older home in Keller or Fort Worth shouldn’t mean constant battles with pests. By combining a proactive approach to pest control with a focus on electrical safety, you can create a comfortable and pest-free environment for you and your family.
