My garden survived thanks to The Guardian

Using the Guardian with deer — A four month case study

Summer 2015 — Courtesy of Biologist Todd Hobein

Local biologist Todd Hobein is a science teacher for the city of Ashland, Oregon. He performed thorough testing of the Guardian over several months, and recorded his findings in detail. This is an excellent testimonial to the importance of proper placement and installation.

“I began planting my garden like I do every year at this time. This year, however, I had four-legged visitors I did not plan on. My neighbor had decided some weeks ago to build a fence around his backyard. As a result, the deer no longer were able to use his yard as their runway and decided to try mine instead. In the early part of June I saw my first deer. After a brief look around my garden I immediately noticed that something had clipped the tops off of my Anaheim peppers. No other damage was observed at that time. I decided then to look into pest deterrent options to protect my garden and purchased the Guardian.

June 15th

  • Observed large doe eating tops of peppers.
  • Upon further inspection, the peppers were too far away from the motion sensor.
  • Moved Guardian from where deer were entering my yard to a location that covered the entire garden area.

June 16th

  • Watched another deer walk through backyard straight for garden.
  • Deer was clearly irritated by the sound of the Guardian by cocking its head and ears to deflect sound (see Image 1).

July 1st

  • No deer were observed in my garden since moving the unit.
  • Neighbor observed several deer wandering around the field outside of my garden but did not enter my property.

July 5th

Noticed some of the branches on my tomato plants had been eaten that were outside the range of the unit's sensor.

I observed no new activity or disturbances in my garden, however I did notice that many of my neighbors have gone to great lengths both in labor and expense in deterring deer from their gardens by building fences to protect their plants — when all I needed was the Guardian.

July 15th

  • Noticed that the peppers had been eaten down again.
  • Upon closer inspection I realized that the tomato plants had grown so much in height that they are now blocking the sensor of the unit for that part of the garden.
  • Raised the unit to point over the tomato plants.

August and September

  • Upon my return from vacation I found many new piles of deer scat both in the garden as well as outside of it.
  • Amazingly none of the plants had even been touched!

There were a few times when the deer did get the better of the unit, however, on each occasion this was due to factors that had nothing to do with the engineering of the unit. External factors like plant growth or plants outside the range of the sensor were the main causes of these trials and required simple adjustments for the Guardian to achieve its full potential.

The protection provided by the Guardian was more than sufficient and allowed me to have one of my best harvests yet from my garden.

The Ultimate AT really works

By the way, this is the second time I have dealt with you and it is always excellent service. Furthermore the product really works and last winter was our first animal free year in 15 yrs! Many thanks.

Recommend to everyone!

I just wanted to recommend [the Ultimate AT] to everyone!

I had a mouse issue in the house. Not a bad one. But when we found the bread on the dining room table with small holes in the bag, we knew it was bad enough that it was time to try some other tactics. (Side Note: I still don't know how they got up on the table.)

I sealed the house up; that didn't work. I laid traps and poisons down; that was a hit or miss. Plus, it grossed my family out to find dead and smelly mice in the house. With a new puppy, that wasn't an option. I tried other sound repellents — the junk they sell in stores. When I actually saw a mouse sitting on the sound repellent one day, I though to myself, “This is hopeless!”

I bumped into [the Ultimate AT] online. I was extremely skeptical about these products that use sound to repel mice! I fell for this trick once already. This 5-In-1 technology and scientific research they showed intrigued me. I'll admit that $49.95 for one unit seemed steep to me, but I figured that perhaps you get what you pay for and gave them a try.

I bought 2 and got 1 free. I plugged one in the kitchen (where most of the activity was), one in an upstairs bedroom that had been having some issues, and one in the basement. No issues in the basement, but since I had 3, I figured I'd use it. It's been over a month now and I haven't seen one mouse or any evidence of mice. The room upstairs — no mice! The kitchen, which was the hub of activity, nothing so far!

It's cold and mice love to come indoors this time of year. I'm very pleased. My 7-month-old Labby had a minor issue the first day I plugged the units in, but the next morning, they didn't appear to bother her anymore. Great product! When these finally wear out, I'll be ordering some again! Thanks.

The sprays I applied GENEROUSLY and FREQUENTLY in my attic worked for a few hours to a day or so. Then I got one of your Guardians. Worked well, but every once in a while I could hear a squirrel in my attic.

I bought two more of your Guardians and installed them in my attic, so that every direction in the attic was covered. PERFECT! Not one scratch. (I set the devices at [frequencies] 5, 6, and 7.)

Thanks. And I don't think there is anything wrong at all in your suggesting that more than one device might work better than just one.

The bats have not returned. Hooray!

Item reviewed:

I simply had to write you. While I purchased the Guardian for helping with some voracious squirrels, just this past week some bats got into the walls where squirrels had chewed a wooden panel below the soffit. I reset the Guardian to annoy the bats.

After one very noisy night (they were unhappy — LOL), they exited the building and have not returned! Hooray! I will keep the unit plugged in and working until the entrance is caulked. Thanks for a great product!

Extremely effective in protecting against the Bambi population…

Item reviewed:

Thank you so much for helping me order more Guardians. They are extremely effective in protecting against the Bambi population that would like to use my garden for their personal 24-hour Buffet. While my two-year-old grandson was visiting I turned off the Guardian that was protecting my tomatoes and peppers (the sound and light frightened him). In the excitement of the visit I forgot to turn the alarm back on. The next morning I found deer nipped branches on the tomatoes and the tops of the peppers. The alarm is back on 24 hours a day and no more carnage has ensued. We have just re-landscaped a 100ft bed along our west property line and need to use the next two Guardians to protect the rhododendrons, hydrangeas, and dogwoods. Great Product!

Austin, Texas… home of the bugs and critters.

Item reviewed:

I purchased your top products for our home in the woods… raccoons and squirrels were playing in our attic and had broken into the screened in back porch to eat my cat's food night after night, and repair after repair to block them. From the time that we plugged in the outdoor and indoor units [The Guardian and Ultimate AT]… no more raccoons, squirrels, bugs… there have been a few poor roaches that have shown up every now and then but look all beat up, stagger around for a while and drop dead. All I have to do is sweep them up. Do you ever recruit network/local marketers? I live in Austin, Texas… home of the bugs and critters.

No raccoons on my roof.

Item reviewed:

I purchased the Guardian (AC adapter included) from Good Life in June 2008, as I was having a problem with incessant squirrels on the roof of my mobile home. However for various reasons, including that I did not find the instructions easy to follow, I did not end up using the machine at that time.

A week ago, a number of raccoons started spending the night marauding up and down my trailer roof feasting on a large crop of apples on a tree up there this year. The first night this happened, I was awake till 5am, despite hosing the roof down with an intense water jet at intervals.

The following day, I dug out my Guardian, and got it set up. For the last three nights, no raccoons on my roof. I am delighted with the results from using this product.
