When it comes to securing your home or business, many people fixate on buying and installing the correct alarm system as well as maintaining it effectively. However, there is always a hidden fiend that is often overlooked and that is pests. Pests, whether they be insects, rodents or small animals, can inflict serious damage to your security alarm system. Pests can destroy wires, boxes, mounts and infrastructure needed to run the alarm system, compromising its effectiveness. Maintaining regular pest control is not only important for hygiene – it is also necessary to maintain your security alarm system.
Ways Pests can Damage Your Alarm System
You may be shocked as to how many times pest activity in the background has caused alarm systems to mal-functioning. Here’s how:
🐭 Rodents Chew Wiring
Rats and mice love to chew electrical wiring. If they’re in your roof, walls, or in the control panels, they will sew the connections together, or simply cause a short on the overall alarm system.
🕷️ Insects Nest in the Sensors, Panels, and Hardware
Roaches, ants, and spiders often find shelter and warmth in devices—probably some of the favorite spots to nest are alarm control boxes, motion sensors, and outdoor sirens. They can cause false alarms, or system errors, or simply cause total sensor failure.
🐦 Birds Nest Near Outdoor Devices
Birds may try to construct a nest on or near outdoor devices such as cameras, sensors, and alarm boxes. Their droppings combined with nesting material could totally ruin the device or block the field of view.
Signs Your Security Alarm System Could be Impacted by Pests
Regular, random false alarms with no apparent cause
- Motion sensors or door/window sensors are not completing their task.
- Visible nests of insects or rodent droppings near their alarm panels
- Wires that have been chewed through or parts or components that have been disconnected.
- Error messages or power interruptions
How Pest Control can Prevent Alarm System Issues
Professional pest control can save and absolutely protect your alarm system in the following ways:
- Avoiding rodents and insects being attracted to critical components
- Preventing nesting in or around the outdoor devices
- Reducing the odds of damage to wires or interference with sensors
- Helping achieve a longer and more reliable system
If you can consider pest control as part of general home upkeep, like cleaning your gutters or servicing your air conditioning. It is preventative maintenance that may save you on future alarm system repairs.
Alarm System Maintenance + Pest Control = Full Protection
To get the most from your security system setup, pair regular alarm maintenance with regular pest control. Here’s what you could do:
- Have your professional pest control every 3–6 months
- Seal entry points around the home or building
- Keep your alarm devices clean of dust, webs, nests, etc.
- Schedule your annual alarm servicing with a certified technician
