Bird-X Yard Gard User Manual


I. INTRODUCTIONBird-X, Inc. has been recognized worldwide as the bird and pest control experts for more than 50 years. Bird-X specialists are able to analyze problems and makerecommendations based on each customer’s specific situation and needs.


  • Droppings are unsightly, unhealthy, and potentially fatal.
  • Droppings cost money and time. “Cleaning up” represents costs unrecoverable by revenues.
  • Pests are destructive and deface property.
  • USDA, OSHA, health boards and other organizations can cite, fine or shut down companies for pest mess problems.


A. Survey the pests and their entry, exit and feeding habits.B. Inspect your property. Discover what the pests find attractive about your area, and if the same conditions prevail in neighboring properties.C. Remove inducements. Clean the area of all evidence of pests and the residual scent. Because pests and their droppings can cause many diseases, use extreme caution when removing them. Do not breathe or come into direct contact with them. If you have questions about how to do this safely, consult an expert. Remove food spillage, garbage, nesting material and other appealing items.D. Maintain a clean and changing environment. For maximum effectiveness, periodically repeat C) above and relocate or reposition the unit, vary the output, or turn it off for a short time.E. Install early. It is always best to install the YardGard before “pest season” begins, as it is easier to discourage them than to rout them out once they have already established a pattern.F. Use products synergistically. Two or more different kinds of devices (YardGard plus netting and/or a taste or smell aversion) will produce a synergistic effect –i.e., in combination, the products will yield much greater effectiveness than the YardGard alone. Contact Bird-X, Inc. for information on “companion” products.G. Consider alternate locations. Make educated guesses as to where the pests will go when they leave their current infestation area, and consider purchasing units to cover these areas as well.


This adjustable-frequency, dual-operation, weatherproof unit deters cats, dogs, deer, armadillos, rodents, bats, insects and raccoons. An infrared motion sensor is built in.


Gently pull off the back cover. Set the operation switch (upper right) to OFF. Turn the frequency dial (upper left) to the desired pest. On the operation switch, choose “MS AC or Battery” for the unit to operate briefly each time the motion sensor is tripped (works with both an AC adapter and batteries), or choose “CONT. AC Only” for the unit to operate continuously (works with an AC adapter only). Turn “Sensitivity” dial to adjust motion sensor sensitivity

AC Adapter Plug one end into the port underneath the operation switch and the other into any standard outlet. (If using outside, protect the outlet from weather). Run the cord through the notch on the bottom of the unit. Snap the cover back into place

Batteries Install four “C” batteries as shown on the unit. Snap the cover back into place. Expect coverage up to 4000 square feet in a generally oval pattern approximately 80 feet out in front of the unit, 50 feet wide. The speaker projects sound on a horizontal plane in one direction. The lower the sound frequency (clockwise), the greatest coverage. Indense foliage and/or large acreage, multiple units may be necessary.

VI. INSTALLATIONUse the keyhole slots on the back to mount it on any building, wall or wooden post with nails or screws. Point the speaker at the area you want covered. If installing outdoors, place the unit at least 3 ft above the ground for optimum range.


A. Check that the power switch of the unit is not OFF (in other words, either CONT AC Only or MS AC or Battery). If using batteries, check that they are good. If using the Continuous AC Only power setting, check that the outlet is good. If using the MS AC or Battery setting, only expect activation if there is motion.B. Reread the Pest Management Program section above. Check for and remove unusual incentives.C. Check the dial settings and ensure you have selected a range appropriate to the pest.D. If a specific dial setting causes a squeaking or scratching sound, rotate the dial slightly until the sound stops.E. It is not unusual to hear a “chirping” noise when the motion sensor is tripped and the high frequency sound turns on and off.

VIII. PRECAUTIONSEven though the top range of the YardGard, 25 kHz, is above human hearing range (which averages, at top level, about 16 kHz), the intensity is great enough to present a chance of damage to the ear if it is directly exposed for an extended period of time at a distance of less than 10 feet. These units should definitely not be located at or near a place where someone will be located for a long time. Normally, this type of unit is located outside pointing away from a house or structure, or indoors in a rarely occupied attic or basement, and thus presents no problem when located in this manner. We suggest that when you are sitting or working within range of the unit, you turn it off, as human presence will normally deter the pests. Some people with good high frequency hearing will be able to hear the unit at its lower frequencies. If this occurs,select a higher frequency.

Do not aim the product into neighboring yards or public areas, or at caged or leashed animals. Yard Gard is intended for use on your own property only.


As with any electrical device, do not place the unit in or near water and do not mount it while standing in or surrounded by water. Yard Gard is designed for use outside, but no speaker can be fully waterproof. The holes in the speaker that are necessary for sound to escape the unit also create small vulnerabilities for water to get inside in extreme weather conditions. Large amounts of water getting into the unit may cause it to stop functioning. To protect your unit from damage:

  1. Do not point the speaker upwards, as this will cause water to enter the unit every time it rains or snows. Face the speaker outwards parallel to the ground.
  2. Do not allow snow to accumulate around the unit
  3. If severe weather is forecast and the unit is deployed in an exposed location, bring it in or protect it with a heavy-duty plastic bag.

If your unit gets wet:

In most cases, if the rings inside of the speakers get wet the sound will change slightly until the unit has a chance to dry out. If this change in the sound does occur after rain, we recommend bringing the unit into a dry area and placing it speaker-down on a towel to drain and air-dry, allowing it 2-3 days to completely dry before re-mounting it.


The YardGard is warrantied against defects in materials and workmanship for a period of six months from the shipping date. At the option of Bird-X, Inc., we will either replace or repair the defective unit. Prior authorization and a returned goods authorization (RGA) number will be necessary from Bird-X, Inc


X. SYNERGY AND OTHER PRODUCTSFor best results, Bird-X, Inc. always recommends that the YardGard be used in conjunction with one or more other products. The combination of different types of control methods has proven to maximize the effectiveness of pest animal control programs.

Quick guide to achieving maximum success with your YARD GARD

  • Turning the frequency dial all the way clockwise (11 o’clock) is the strongest setting at the lowest frequency. However, that may not specifically target the animal you aretrying to repel. The larger the animal, the lower the frequency it hears. Please use the chart under the dial as a guide.
  • The unit at its lowest frequency is in human range to some.
  • Motion Sensor operation is highly effective for most pests in most situations. For maximum effectiveness in challenging infestations, Constant ON is the most effectivedeterrent. You must use the unit on AC power for Constant use.
  • The unit works on a line of sight. The ultrasonic frequency travels outward in a cone shaped pattern. Place unit in an area where you will achieve maximum coverage. Raise unit two to three feet above ground or at eye level of pest.
  • The sound waves cannot penetrate through solid walls or objects, they ricochet off of solid surfaces (i.e: walls, fences large trees, etc.) and tend to be absorbed by soft surfaces.
  • The range dial only needs to be adjusted if using the Motion Sensor.
  • The chirp sound is normal when unit detects motion or when first turned on.
  • Although the unit is harmless to animals, your pets may avoid the area that’s within range of the unit. They cannot hear the unit unless they are within range of it.
  • The modification of an animal’s behavior takes time. Please allow two to three weeks to achieve results with the recommended settings. Try changing settings once a week.

Typical Yard Gard Questions and Answers

How long do the batteries last?Depending on usage, the batteries last about 1 month while on the MS mode

The unit will not turn OFF while on the MS mode. What can be wrong?The unit stays ON if the batteries are low and need to be changed.

Why can some people hear it?Sounds are generally audible to the human ear if their frequency (number of vibrations per second) lies between 20 and 18,000 vibrations per second, but the range varies considerably with the individual. However, some mammals can hear well above this (bats can hear over 100,000 vibrations per second). The Yard Gard operates at 15,000 to 25,000 vibrations per second

How do I change the light bulb in the motion sensor?You can’t. You will have to purchase a new unit if it is past the 6 month warranty.

Can my dog/cat hear this?Yes, but it will not harm them or bother them unduly if it is not facing them.

How do I know it’s working?In the “Cont. AC Only” setting, the red light should be on. In the “MS AC or Battery”setting, the red light should come on when something passes in front of the unit. Also, the unit should make a chirping noise when turned on and/or when the red light (see above) first comes on.

Why does it make a chirping noise ‐ I thought it was supposed to be silent to humans?The chirping sound is the unit powering up or when you use the motion sensor either with batteries or electric. It needs to travel through the audible sound levels before it reaches the ultrasonic frequency. The chirp is normal.
