Please log in for more thread options usual suspects (trees), but still no joy. I thought it might be a spider, so I evicted one tonight. But it seems to be doing it again. Assuming the spider is back, any human safe home remedies for keeping spiders out? | |||||||||||||||||||||||||||||||

Please log in for more thread options It's called silicon (pronounced "silly-kon"). It comes in convenient tubes. Use lots. :-) | |||||||||||||||||||||||||||||||

Seal the wire and screw mounting holes with a dab of silicon sealant (bathtub caulk works well). Cut a small piece of sponge and, while wearing disposable gloves, saturate it with Raid or any other anti-critter stuff. Place the sponge inside the motion detector and close the cover. In the tightly closed space the stuff lasts for years. It doesn't seem to harm electronics but just to be safe I keep the sponge away from the wires and PCB. Please note that spiders and other critters are only one possible cause. If there's a hole in the housing, seal it to keep drafts out. Cool (or warm) air blowing directly onto the pyrolitic transducer can wreak havoc with a PIR. Make certain the detector is firmly attached to a non-moving, non-vibrating surface. The least motion of the detector appears to the unit as though the whole world is jumping around. -- Regards, Robert L Bass =============================>

There's a gasket around the lens and a foam block around the sensor wire. Although I didn't happen to notice the state of the foam when I had the lens off, perhaps it's hardened up with time. > --

I'm not certain it is a spider but they can and do get through some really small openings. In inner city jobs I've occasionally opens a suspect motion detector and seen half a dozen roaches scatter away. Yick! -- Regards, Robert L Bass =============================>
