Deter Garden Pests Such As Deer or Neighbors




This whole rig probably costed me about $35 and will last forever. Difficulty: Medium-Easy

Step 1: Basic Setup

For this project you will need...

A Motion sensor......Lowes $20

Some water proof house wiring (gauge 12)......approx $1-2

Plasic beads......$0.5

Leather strip( you can cut a little off of your sons baseball mitt if you have to you only need like 3-4 cm)

An old small tupperware container

Kitchen silicone Sealer ......$2

Electrical outlet......$3

Replacement plug (in wire)

Outlet cover and box

Aon old watertight container(I used a kitty litter box)

Optional Spraypaint.

Step 2: Getting Started

First cut two holes in your large watertight enclosure (kitty litter box) one for the motion sensor and one for the power line. where they are put is up to you. Attach the motion sensor to the hole with the appropriate cover seal all cracks with the silicone. do the same with the power line.(see picture below)attach the appropriate wires to each other( power to the sensor).

Step 3: Finish the Wiring

Now add the Outlet box and appropriet hardware to the setup. (I used hot glue to secure everything, the 2 by 4 is for support) depending on what type of enclosure you are using you may need to use a different setup. REMENBER TO SEAL EVERY CRACK WITH THE SILICONE! Now we wait for everything to dry.

Step 4: Choices...

Now you have to choose...

Depending on the type of pest you are dealing with you may have to coose a different solution.

For pretty much any pest i'd reccomend using an ultrasonic emmiter (target, this isn't a good solution if you have a dog or cat)

For above ground pests I used sound in general.

I used a small motor inside a tupperware container full of beads. I attached a peice of leather to the axle for even more noise.

Step 5: Putting It All Together

Now add the solution device to the rest of the setup, put on the lid, plug it in, and TADA! you've just made an extremely effective pest deterer(the one I made worked well on deer, raccoons, and other warm blooded above ground animals. (make shure the setting on the motion sensor is set to 'TEST' mode so that it will only go off for 5 seconds or so in day or night.

Step 6: Other Ideas

-paint the outside to match your decor

-using more wire make an external/extended range motion sensor and hide the box

    I did something similar, a took a small motor from a hobby band saw that was a piece of junk, made in China, motor was all that was working, so I kept it, the large rubber wheel on its shaft was ok too, I drilled four holes in the wheel, atached four nylon or parachute cord strings and large plastic beads on the ends. I have remote switches all over my houses that I can activate by a console with numbered switches. I set one switch to the motor and put a bucket over it. A heavy brick keeps it down and above the motor. I also have a motion sensor that works on day or night that is connected to a small low voltage transformer with a tiny beeper inside my home. This tells me something is out side and going to eat my plants which are in half 55 gal. tubs on my back deck! . When I hear racoons or possoms on my deck at night I hit #2 and the motor spins, beads smacking the inside of the bucket! Very loud and the critters leave very fast! Works for deer too! And 2 legged critters as well! They never see it coming! Everything is sealed in ziplocks or 2 liter soada bottles to keep out moisture. The wires are siliconed in at the ends too! I'm thinking of making an 'ible of this right now! Watch for it!

    Well, I was hoping this was something to do in the possums that invade my back yard so I wouldn't have to beat them to death with my rake anymore. Alas, it seems it won't. But maybe, when I finally quit LOL so hard it hurts...maybe I'll try making one or twelve to try to scare them into PLAYING dead. I like the Halloween idea, too. I'll bet several of my sadistic (but loveable) neighbors would be interested!

    Very nice. I wonder what it would take to make the sound of a rattlesnake? That would keep some human pests away. How long have you had this in operation? Have the pests gotten used to the noise?

    So, it detects motion and makes a scary noise?

    That's rather clever.

    You could add flashing eyes and a pair of flapping wings as well, keep children off the orchard.

    Or hide it in a bush near your front gate on Hallowe'en!

    I actally came up with the idea on haloween...but after the fun was ove decided to use it for this, and it worked really well!

    He has a good point there. Somebody should try rigging up a rifle or make the box an explosive device to bring in dinner every now and then...
