This is a customizable rodent vacuum for testing. You print what you need and configure the rodent vacuum. I included one three-part pipe entrance with a bait tray and latch design.

Some potential benefits of this trap:
• This trap can be configured as a catch and release or not.
• It can be safer vs snap traps and poison.
• Can attach to wall and mimic a plumbing pipe.
• Automatic reset and multi-catch.
• Can use a lot of bait to lure the mice or rats in. Rats have a strong olfactory.
• Can be setup as a smart trap to get alerts on your phone.
• Can use existing equipment and materials you already have.

Instructions and information:
This trap uses the Westek MLC12BC-4 for the motion setting and a vacuum with a 2.5” hose that is 10amps or less. A Ridgid HD1200 should work or something similar work. I designed this to be able to 3D print the parts or you can substitute a 3” ABS pipe and 3” hose clamps from the local hardware store. You could even use some aluminum foil possibly doubled or tripled up as a bait tray. Maybe bent around the front of the pipe and the cover pushed on or taped at the front. This will save a lot of print time. I made the pipes 250mm long. Check if your printer can print this length.

When using the Westek and bait box I drilled the hose with an offset of 3 1/8 and 3 1/2 from the back of the pipe. You will need to drill about a 1 1/8”-1 3/16” hole. You use the existing screws that come with the Westek for the sensor lid. The Westek has a 100° degree field of view so note that when placing it on the pipe. You don’t want to put it to close to the entrance giving the rat or mouse a chance to escape.

If you get a rat or mouse that tries to chew on parts. I would recommend trying some HVAC aluminum foil tape.

See this video on how to cut the lip off a bucket to be able to double them up. https://www.youtube.com/watch?v=1WnitgYFnE0. I included an adapter to connect the rodent vacuum directly to the side of the top bucket and also a Wyze camera adapter for the top inside of the bucket. You maybe able to use this to push the rodent vacuum up against a wall or table. The water in the bottom bucket can provide some stability. The bump on the bucket washer identifies the top and you may need to use some silicon on the washer to get an air tight seal. The rounded washer straightens the curves of the bucket so you can screw the nut on and distributes the pressure on the bucket plastic.

The Wyze Camera v3 holder should be compatible with most drywall screws and making it capable of mounting on a wall.

I put mount holes on the pipe entrance to make it capable of mounting to a wall, bucket and down against a board.

When using this you will want to oil/lube the vacuum hose inside. If you decide to use water you might want to also use a fragrance and soap. You want to lightly pre-bait the outside of the pipe and a liberal amount in the bait tray and/or jar. When setting up the hose keep it straight as possible without curves or turns. Test and make sure your shop vacuum is on. I would test with setting the Westek timer for 4 seconds.

I made different size adapters and connections. So, test and leave a comment what works best. I may improve or modify the parts based on the comments.

**Note: I don’t own a 2.5” shop vacuum so I haven’t tested and I haven’t tested this trap in use.
