We are only months from summer, and summer is Pest Season. Depending on where you live, pest season could be seasonal or every day. Your garages serve the purpose of protecting vehicles, storing items, and can even double as additional workspace.

While the garage is a practical and adaptable household area, it’s also often home to a range of bugs, rodents, and other pests. During a hot summer, insects are looking for a reprieve from the heat and are in need of reliable water source. When you drive a wet car into the garage after rain; water drips on the floor permitting bugs access to water. So unknowingly, you could be building the perfect home for the unwanted. While in the winter, the critters need protection and warmth. Finding critters in your garage is often unsettling and inconvenient, but there are several quick methods to remove unwanted housemates and help minimize future infestations.

As a homeowner, you are probably accustomed to finding pests and insects on your property. These sightings can range from a minor inconvenience like flies or gnats buzzing around to major problems that can lead to property damage, such as mice and birds nesting within the walls and ceiling. Most pests seek shelter in garages because they often represent a steady source of food, water, nesting opportunities, or light.

The most common types of bugs and pests you’ll find in garages include:

  • Flies
  • Silverfish
  • Crickets
  • Spiders
  • Cockroaches
  • Ants
  • Moths
  • Mites
  • Mice
  • Birds
  • Squirrels
  • Rats
  • In some places—Snakes (to me a snake is like a helper that eats rodents and insects). If you suspect the snake is poisonous, then by any means call in an exterminator.

    If you’ve recently found bugs and other critters living in your garage, it’s important to remove them quickly and take the necessary steps to prevent them from returning. Some critters like Mice and squirrels can be hard to get rid of. Squirrels usually enter an attic through an opening in the roof or soffit. You can minimize bugs and pests from getting into your garage with these solutions:

  • Remove existing critters: Incorporating preventive measures throughout your garage won’t do any good if there’s already pests nesting in the space. Inspect your garage and note any signs of an infestation, then call a pest control company to remove any bugs or pests.
  • Inspect your roof and house for holes: A mouse can fit into really small spaces. A mouse can fit through a hole as small as a nickel. It is the same with birds. Once they begin to breed, you will have a population explosion on your hands that could take years to reverse. Birds can be a big problem also with a special focus on pigeons. Pigeons are dirty birds that will have parasites and bird mites in their droppings when they defecate. If you come in contact with pigeon poop wash your hands immediately. If you accidentally transfer pigeon poop to your eye, you can go blind from a disease that only pigeon’s carry. Once birds nest in your garage, they will not leave until their eggs hatch or they are driven out. The offspring may return the following years to nest in their birthplace. To stop the vicious cycle, you may need to get cruel and kill the birds. For me that would be a last resort. A more humane approach is you can purchase a plastic owl at a garden center and place it on a pole outside your garage. This usually will keep birds away. If they ignore the owl, then position it in another spot until you find that sweet spot that scares birds or rodents from your area.
  • Clean out the garage: Once all insects and pests have been removed, clean out your garage by sweeping the floors, removing debris and replacing boxes with plastic storage containers. If you mop your floor with a 50/50 vinegar and water solution, it can deter critters from entering your garage for a few months. Keep containers and other items on shelving to eliminate hiding spots and nesting opportunities. Remove any food and place pet food in airtight containers. Then, look for moisture sources and dry any standing water with a portable fan. If your garage ceiling leaks during rain, then patch it or place a pale where the water drips to keep a puddle from forming on the floor. A bag of dogfood will attract almost any critter. One evening while walking into my garage I noticed 2 crickets munching on a small chuck of dry dogfood. The next morning, I placed the bag in a plastic container and stored it high on a shelf. However, the cricket infestation continued through the entire summer. Crickets are typically not scary. It’s the noise that is annoying. Typically, I am not worried about critters except the odd wolf spider or black widow spider. Living in Arizona, I have had to deal with scorpion’s every year, which are the most horrid critter in my book.
  • Many homes in Arizona employ a gas hot water heater. The building code calls for ventilation in the garage when natural gas is used. The problem with the vents is the openings are too big, which can permit the insects mentioned a doorway in and out of the garage. To remedy the situation, I had to purchase fly screen and tape in onto the normal vent openings. This helped out a lot, but there was one more place that needed more work to keep out the uglies. My home was brand new meaning the cheapest weather seal were employed. Especially on the garage door bottom seal. Being in garage door business, I was able to locate replacement rubber door-seal and replace the dry, worn out piece that had stopped sealing the door to the floor years before.

    Do this also:

  • You should inspect: your garage door weather seal and weather-strip on the entry door every spring and because of the many different designs, it would be prudent to call a professional garage door service company. They will provide the correct replacement and seal out the pests for good. If the correct rubber astragal is not found, a garage door service company will employ another type of seal. You may choose to purchase extra weather seal from the serviceman, so you can make your own repairs later down the road.
  • Inspect for cracks: Prevent pests from entering your garage by checking for cracks in the foundation, walls, and ceilings as well as gaps in exterior doorways and windows. Seal any gaps or cracks with silicone caulk.
  • Lay traps: For sneaky pests that still find a way into your garage, set up traps around entrances and spray pesticides around doors, windows and along walls.
  • Insecticides works well most of the time. Keep that in stock all the time and spray the garage floor whenever necessary.

      We have a 2011 Ford Escape with an Interior System for operation of Exterior Gates, Garage Door and House Security Lights. I am unable to Program the Guardian 630SL with the vehicle equipped system which worked with the other Garage Door Opener our home had. Is there a reason I am unable to set up this Opener purchased from your company using the "Guardian Remote Clicker" the only answer to this inconvenience ?

      There are two systems auto manufactures supply with their cars, HomeLink, made by Gentex and Car2U made by Leer Corp.  Guardian operators are compatible with HomeLink, but not Car2U.  Please check your car's owner's manual to see what system is used in your vehicle.  There should also be a phone number in the manual to call for help in programming either of the two systems.

      I have two guardian remote controls that do NOT open our Guardian garage door opener. I have replaced the batteries in both units, and they still do not work. However, the external wall mounted wireless garage door opener works, as well as the embedded garage door openers in our Honda cars. So what is not working are the two guardian remotes. Please provide some direction to troublehoot and solve this issue.

      Thanks in advance...Scott

      Hi Scott,

      Have the remote controls always worked with the garage door opener or is the issue something recent?  The fact that the HomeLink system in your car is working indicates that the radio receiver in the opener is working.  What are the model numbers of your opener and remote controls?  To talk directly to a tech who can help to troubleshoot, call 1-424-272-6998.

      Is there a way to put the lights on the opener in "motion" mode, rather than just coming on by pushing the light button or opening the garage door?

      Dear Alayne,

      Some gargae door openers have a special control console that can provide this function.  Your Guardian opener is not adaptable to this console,  A less expensive alternative would be to replace the light switch in your carage with a passive infrared motion sensor wall switch.  This switch will recognize a presence in the room/garage and turn on/off lights accordingly.  A garage door opener system works with a set timer, so lights can remain on even after the person has left the garage.  The switch could be purchased at any hardware of store or home center.

      I recently posted complaining about the motor. I found a number for Guardian technical services online and as a last effort I called them. Technical services was great and helped me fix the problem fairly easily with directions over the phone. I’m impressed with corporate but still disappointed in the local installer as since the day they installed the opener they come across as more interested in generating charges than doing what’s right for the customer.

      Thanks to Technical Services!

      I'm in New Zealand. If I can't source this for my Guardian 21230DL, I'll have to discard an entire garage door opener which works perfectly well just because it can't receive the signal from the remote.

      I looked for an internet sale on your website but couldn't find it.

      Considering that it will cost $800 to replace the whole door opener unnecessarily, I would really appreciate your help.

      My garage door motor is beeping every 15 minutes. Is this due to my remote battery being low or the motor being low? I'm having trouble locating a batter on the actual motor.

      I read the comment on how a clicker is not universal and will not work on guardian garage doors. Specifically could you please suggest one that will work? Your tech phone number is useless! I've left two messages and not received a return call yet and its been three days. No one ever answers either.

      My garage door will not work with the wall panel unit. The remote control units work and the keypad outside works. Any suggestions?

    1. Brian's picture
      May 14, 2018

      Hi Sherri,

      Is the LED back light on the panel glowing?  Check the wiring first.  The plug on the end of the wire leading from the control banel should be securely plugged into the "wall box" recepticle on the motor head.  Check for any wire shorts due to staples holding the wire to the wall.  Check the wire terminal connections on the back of the panel.. If more help is needed please call 1-424-272-6998.

      Lost power and opened the garage manually, power came back on the door opened almost completely and stopped. Beeping 20 times checked no lights on. Metered the wires for power, 21.08 tried aligning can't get any LEDs on?

      No lights on the photo eyes. I think the logic board is out. Can you help me?

    1. Brian's picture
      Jan 07, 2019

      Hi Clinton,

      If the operator still opens the door and a constant pressure on the push button (PE override) closes the door, then the circuit board is probably not the problem.

      1. Check at the operator head to see if wires are in the 4 photo-eye terminals.  Sometimes installers will twist wires togther and use only 2 of the terminals.  This reduces power to the photo-eyes.  It may work initially, but over time as the wire develops more resisitivity, power declines.

      2. Check the alignment of the eyes.

      3. If LEDs fail to appear, after careful alignement, then replace the phot-eyes.

      4. Call 424-272-6998 for further help.

      I have no lights on my photo eyes. I have two garage door openers and tried the logic board in the other opener and the lights would come on. This tells me the logic board is good. Wondering if it might be the transformer.

      Jan 23, 2019


      If you plug the photo-eyes that do not light-up when plugged into operator A into operator B and they light-up, the eyes are good.  Replace the logic boaed in operator A.

      Call 424-272-6998 for additonal assistance.

      Hi Roy,

      Thank you for the blog. We have a Guardian Pro Series 628 which was installed about two years ago. We have constant problems with the sensors and believe this is cause by glare from the sun since we experience the problems mostly during the day. Are there specific safety sensor sun shields (that's a mouthful) that work with these units? Also, the green light on that side blinks slowly all the time but the door still goes up/down. Is that normal? I thought both lights should be solid.


    1. Brian's picture
      Apr 03, 2019

      Hi Jim,

      There are no stock sun shields for photo-eyes.  Fabricate a shiled from cardboard or an empty paper tube and tape to the red (receiver) photo-eye.  Another trick would be to reverse the position of the eyes, placing the receiver eye on the shaded side (if there is one eye in bright sun and the other in the shade). 

      You are right, both red and green LEDs should be steady.  The flashing green could be due to misalignment or a poor connection at the operator head.  First, check the PE alignment.  If necessary, remove the wing nut holding the sensor for full range of motion.  Next, check the terminal block on the back of the motor head.  The first 4 terminals (L to R) are for photo-eye wires.  Each terminal should have one wire inserted.  At times, installers twist together pairs of wires.  Not using all terminals cuts the ammoun of current avaialble to the sensor and could cause the LEDs to flash.  If these two steps do not work, call 424-272-6998.

      I bought a Guardian Garage Door opener and from day 1 it has been temperamental when using the remote to open and close. If i am too close or push the button to long or too short a time. I had the installer return and ask questions, it appears Guardian knows their problem is the RF signal being sent at too rapid a rate or something of the like.
      DOES GUARDIAN HAVE A SOLUTION TO CORRECT YOUR ISSUE? At present i would never recommend this product or ever buy another, my second door will not be replaced with a Guardian.
