The DU Lounge
Related: Culture Forums, Support Forums2fer: 1) Update on snail/beer problem/solution. 2) Lounge, settle non-bet/quarrel about electricity
1) I had heard for years that garden snails could be de-pested by treating them to free beer, where they would imbibe and therein *drown." So I tried it, using (aluminum?) cupcake forms, masking taping to the tree/bush trunks where the snails were glued. I expected them the next morning to be drowned. Results: Not ONE of them moved from being stuck on the plant. Are they DEAD? Are they sucking the life out of the plants? Anyway, I have done the rounds of ripping off all the masking taped cupcake contraptions. The only casualties were some bugs who, indeed, imbibed and died. Not the snails.
2) I've always readily admitted to my ignorance, but also willingness to seek knowledge especially from Lounge. So about electricity: When you flip the switch *OFF* does it cut the current? Iow, there's this motion sensor bulb thing that yet has to be activated by switch for On and for Off. I subject myself to trekking over nights to flip "On" and in the A.M. to flip "Off." A local know-it-all who has had some electrical training sez I can just leave the switch "On" permanently. I contend that this leaves current passing and therefore $$$. Know-it-all sez not the case. I will accept Lounge knowledge.

(7,634 posts)Current follows the path of least resistance. If I understand correctly, you have a light that is sensor activated but is also on a switch. That sensor is basically a switch as well. If its not activated, the circuit is open and has infinite resistance. No current will flow through.

(58,670 posts)There is a slight amount of current flowing to keep the sensor activated, but it would typically be in the milliamp or even microamp range. During the time the sensor breaks the circuit to the light, the charge to your electric bill would be a couple of cents per month.

For (2), not sure what you are getting at....but I think on or off, you are talking pennies.

(7,634 posts)If its a 60 Watt bulb, then it will use 60*24*365/1000= 525 kWh per year assuming its lit 24 hours a day.
The average cost of kWh in the US is 12 cents. So, it would cost you about $63.00 per year.
In reality, you keep your bulbs on maybe 3-4 hours a day during the evening (more in winter, less in summer) so a single 60 W bulb cost about $15.00 a year to run. I can see that if you have 6-7 lights on all the time in the evening at home, it could add up over a year.
The OP has a different situation in which he has a sensor attached to his light and also a switch on the same circuit. As long as the sensor does not turn the light on, he is not using any current since the sensor keeps the circuit open.

(7,634 posts)that would be 1*24*365/1000*12/100=$1.05 per year Its well worth the convenience of keeping it on..

(115,735 posts)The slugs will crawl into a low saucer of beer placed on the ground, which is the only way I've ever heard of this being done. It might not work for snails, or if in cups on trees.

(55,014 posts)sort of hibernating like bears. if you see slime trails in the morning (looks kind of like dried snot on things) then that means they are moving around at night. if they don't move they are probably waiting for better conditions (moisture, temperature?) or maybe they are indeed dead.
I found this one last fall in the middle of a desert area more than a mile from any kind of water or moist environment, it was dead. Probably parked into dormancy 4 or 5 months before when it was rainy and then dried out completely since it never rained again.

(70,711 posts)& validating your info, there are no slime trails.
Now I'm stuck with 5 cans of the cheapest, hot beer!1
