Safeguarding Your HVAC System: Preventing Pest Infestations in Autumn and Winter

As the colder seasons set in, the warmth and shelter provided by HVAC systems become inviting havens for pests such as ants, rodents, and insects. However, these unwelcome visitors can cause significant damage to your HVAC unit, leading to costly repairs. To safeguard your system, you must understand which pests you might encounter and how to prevent their intrusion.

Common Pests in HVAC Systems:

Rodents:

Rodents like mice, rats, opossums, raccoons, and squirrels are notorious for wreaking havoc on HVAC systems. They can chew through ductwork, damage connections, and even pose fire hazards by gnawing electrical wiring. Additionally, their presence can lead to health risks due to contamination from droppings and urine.

Ants:

In the spring, ants, particularly crazy ants, are drawn to HVAC condensers due to the acidity in the contactor. When ants come into contact with the contactor, they release an alarm pheromone, attracting more ants that can swarm and cause unit malfunctions.

Wasps:

Unprotected or damaged vents and ductwork provide ideal nesting sites for wasps, posing risks to your HVAC system and your family’s safety. Removing wasp nests is a delicate task best handled by professionals to avoid injuries.

Snakes:

While less common, snakes may seek refuge in HVAC units during colder months. They can coil up in condensers or infiltrate ductwork, potentially causing damage to components and posing risks when the system is turned back on.

Signs of Pest Infestation:

Detecting signs of pest infestation early is crucial to prevent extensive damage to your HVAC system. Look out for foul odors, unusual sounds, animal droppings, increased allergy symptoms, or sudden heating or cooling loss.

Preventive Measures:

  1. Call a Pest Control Professional: Avoid spraying pesticides in your vents and ducts by seeking assistance from pest control professionals who can safely remove pests using non-toxic methods.
  2. Seal Up Gaps in Ductwork: Regularly inspect and seal any gaps or damage in duct connections to prevent pests from entering your HVAC system.
  3. Cover Vents and Flues: Install pest-proof vent covers and screens to block entry points for insects, birds, and rodents.
  4. Maintain Outdoor Unit: Keep the area around your outdoor unit clean and tidy by practicing regular lawn care, removing excess moisture, and ensuring proper drainage.
  5. Schedule Routine HVAC Maintenance: Regular maintenance appointments will help identify and address potential issues before they escalate, ensuring your HVAC system remains efficient and pest-free.
By implementing these preventive measures and staying vigilant for signs of pest infestation, you can protect your HVAC system from damage and ensure the comfort and safety of your home throughout the autumn and winter seasons.

Good traps! Read instructions and be patient...

Bought a couple of different traps, had most success with these. They are bigger and seem to be stronger than the others we purchased. And these were cheaper.

Gloves and instructions were very useful.

Keeping human scent off the traps and allowing the rats time to get used to them (baiting but not setting) etc. has helped catch a trap-shy rat.

Work every time - with the right bait

I have a neighbor with a huge overgrown garden (her house looks like a horror movie set as well). Consequently over the last few years we have the autumn influx of critters which move into my sheds for the winter. They even dug under the ground to come in via the floor! I have tried everything available to be kind to them, then to poison them then to trap them. Only death works because there are so many breeding mice next door. These traps are failsafe. Box has warnings in about useless bait (like cheese, peanut butter etc) and also comes with gloves and brushes to get rid of fleshy ick. You need a 2-pronged attack – I have heeded the advice and only put about six grains of poison in the middle well in each trap. I then set trap and dropped only about 2-3 grains beside trap to have a trail going to trap. Every single day I have set two traps as an experiment and every day I have caught two mice.

Note at end of November: I have now caught two mice a day for 16 days – found out they came in via a mole tunnel underground then chewed through a wall. I filled up hole n have no more since – using this method NOT ONE MOUSE HAS BEEN TRAPPED BY LEG ETC and all die quickly by instant effect as their eyes are still open in surprise. Not cruel and no lingering suffering for them, just instant.
