Using motion-activated vacuum cleaner to control camel crickets

For those of you with camel cricket infestations in your basement, this might be of interest. Here’s what you’ll need: vacuum cleaner, motion-sensing light source, Belkin WeMo motion switch, bait. Plug the vacuum into the motion switch and then situate the hose intake perhaps 2″ from the motion switch, as per below:

After all this is set up, bring up the WeMo app on your phone and make the rules you want your sensor/switch to follow. Rule 1 should be: turn on switch / turn off immediately (this vacuums the cricket). Rule 2 (optional) should be: send notification, every 5 minutes (this lets you know it’s working, and when). It’s really nice to wake up and get the report on the night’s anti-cricket war.

Here’s a close-up showing a cricket walking close the motion sensor (the light indicates it has been triggered), then get sucked up. Here’s a short movie.

Camel cricket vacuum

Voila, cricket inside vacuum cleaner. Just empty it out every week, ideally into a chicken coop.

By the way, I first tested this setup using my Rigid shop vac, but it turned out to be so powerful that the sensor was sucked up, ripping the power unit right off the outlet. If you need that kind of power (to sample mice, for example), just be sure everything is really, really firmly attached.

If you have a camel cricket problem like I do, please also see my “Getting rid of camel crickets” page.

Boating to Bartram’s Garden

One of the gems of Philadelphia is the former estate of John Bartram, a world-renowned botanist and buddy of Ben Franklin (who flew his kite there, I gather). Back in the day, his garden along the Schuykill River was filled with rare and interesting plants collected from different regions of the colonies, had a heated greenhouse, and was a destination for anyone of import who happened to be in the area.  The garden and buildings today survive on a small patch of the former property, an island amid urban squalor and decaying industrial sites.  You can drive there, but I took a boat from downtown Philadelphia (visit www.schuylkillbanks.org for details).  In case you are too far away to do the same, some photographs are below (mouseover reveals description; click to see larger).  The most notable part of the house tour was the thriving population of camel crickets on the ceiling.  The tour guide was annoyed that everyone was so interested in them. If you’re in the area and want to go, get details at bartramsgardens.org. The anniversary of his death is this Sunday (September 22nd).
