Default Anti cockroach laser device

Hello to everyone and good day.

I'm looking to buy an anti cockroach laser pointer. I think its pretty obvious how it should work, point and kill

Do you have something like this here in your forum or can you refer me to a device that does it ?

I would also be happy to buy it from personal build.

Please dont tell me to kill them with things like:
A ladder.
A shoe.
A stick.
A napkin.
A spray bottle of cleaning product...

I know i can do it, but I just hate getting close to them !! and, we are soon in 2012, its time to move on...

Thank you for your help

Alon.

So how do you keep them from running away from the bright light ? From what I understand they scatter & hide when the light suddenly comes on.(or gets significantly brighter.)
A laser that can burn over any real distance would certainly be a lot brighter ! If you try an IR wavelength you would be required to use some sort of night vision or CCD image enhancement to be able to see what you are doing.(And protect your eyes at the same time.)
Methinks that your idea is fraught with problems.

Just my opinion though.

I'd be more interested in how you intend on tracking them. Like SIC ^ said above, as soon as they see a significant light source, they'll take off extremely quickly. And tracking a small black insect running along the floor with a high powered laser saturating the camera is going to be a challenge in itself.

a handheld laser will be tough to aim and fire accurately, and it wont be as "instantly effective" as you might think.

I suggest a BB gun and some construction-type safety glasses for anyone in the area.

happy hunting!

Yeah- a cookie crumb projection- like the 1 milliwatt ones for cats that have a picture of a mouse:

Project the cookie crumb image on the floor to tempt the roach- flick the lens cap and WHAM- hit him with the full 1 Watt Blue.....

Too bad the Laser won't kill them though, it would have to be crazy powerful, scorching floors etc.

Really - much better off caulking every crack between baseboards and floors and cabinets and floors, inside cabinets etc. then on the outside etc etc- every crack and gap should be filled.

There used to be an insecticide foam that worked great as well.

For a laser to burn it needs to be held still, and focused to a small dot. And you will need good goggles to protect your eyes to see the spot, and protect you from reflection.

Also laser pointers are not to the point of the "laser gun". There is no point and shoot. You'd need major power for a quick enough burn, and that would be way to dangerous for indoors.

They have a new roach compound now. It doesnt kill them, but sterilizes them so they cannot reproduce. It works extremely well, and lasts a long time. Spaying for roaches is a thing of the past now.

So once you kill them with the supper laser bug destroyer are you going to get close enough to pick them up

Well, I just spent a few minutes googling cockroaches. I was wondering if they can see infared light, but it wouldn't surprise me if they could, seeing as they are nocturnal. I did however run into this:

While the cockroach can see very well, it's worth noting that a cockroach cannot see in red light!
from here.

If that's true, I'm thinking a high powered red may be the ticket.

cool, i might try that out, but I'm afraid it might not have the strength to kill one. The most powerful red I seen around were mostly 400mw or so. Even a 1 W blue has problems dropping it before they scurry into safety. You need something hotter than the 1W blue in order to do any real damage to the cockroach's shell and I'm not sure if you have a 2w red in the market right now...

I owned a Jayrob/DTR maglight kit, a A140 diode/1.6w with G1 lens, it already have problems unless the cockroach have no where to run, then yes I can kill it, but if the cockroach appears some other places, then GL it would run so fast into hiding before you can do anything to it.

I am thinking about maybe the dual 3.5w by wannaburn may do the trick, go figure

Yeah, I don't know. The plus side is that they won't see the red light shining on them I guess. If the cockroach stays still long enough, you should be able to punch through his shell or boil his insides if it's dark colored I would think. You can get a 300mW red to do some pretty serious burning from a decent distance away. I don't have a fancy lens on mine, just coated glass, and I'm burning through stuff at 6 feet away.

I see. My experience with buring cockroaches with my Joyrob/DTR 445 maglite is that, the insect didn't really get disturbed when the dot is getting near to it, so I determine that the insect isn't very much affected by light, but when the dot touches the insect, it starts running, I could guess it is more likely that it is affected by the heat.

The Jayrob/DTR 445 maglite is really 1 hell of power imagine how much a 1600mW laser can do at close range. But even at close range a 1600mW monster can't drop a cockroach, I estimate like 2mins of burning... Thanks to the massive heat Sink! It is not like constant burning, if it were then any 700mW can do it and I doubt you need that long to drop a cockroach as well. You need the power to hurt it little by little as you shoot it as it expose itself out of the furniture.. burn it's legs, blind its eye, destroy its wings if it attempts to take flight, and slowly drop it to the ground turned-turtle.

If the author wants to kill cockroach, I highly recommend a maglite kit cuz it is really frustrating to chase insects without forward momentary clicky. If it isn't a momentary button, it be worse if it were located at the back, you got to switch it off when hunting so as to cut down as much unnecessary wastage in operating the LD,. Then when you finally spot the emerging running insect, you need the speed to switch it on. I owned a Spartan 1W and it is really frustrating to use that to drop cockroaches.. Not useful at all. And a G1 lens is far more suitable for killing cockroaches than the Spartan.. My advise and experience to the author, hope you make the right choice. I already made a wrong choice and wasted money by getting a Spartan.

My advise to the author, you need a customised Laser hand-held and yea, you need it with focus and G1 lens... And try to get a copper heatsink instead of aluminium, I think the output power can remain more constant with better heat sinking... My maglite with aluminium heatsink is very bad at sustaining at 1.6W so I need to switch it off as and when I am not using it to burn the insect.. I don't mean power of the Jayrob kit isn't efficient enough to kill cockroaches, but the truth is the truth.. The rest of the features like forward clicky are usefull for chasing inseats so I will still recommend it.

IF you get a 300mW red, I highly doubt it can punch through any cockroach shell. It didn't happened for my 1.6W maglite and you know 445nm is best for black surface and cockroaches are naturally darkish brown or black in colour... Even with 1600mW, I already have many numerous experience with escaped cockroaches while trying to drop it with my maglite... For faster kill, I hope a really higher powered hand held exist.... yea my diode isn't cherry-picked by the makers so mine is only a 1.6W Maglite, so seriously if the author wants cockroach killer, afaik such laser hand-held units don't exist on LPF. I don't know if a 2W laser is sufficient to effciently drop a cockroach cuz I don't own one but IF it is sufficient, the laser diode needs to be cherry-picked by the supplier/makers.... And I hghly doubt the supplier will charge the diode the same cost...

Flatten out the wire mesh of a bug zapper and put it where they congregate. Just don't touch it.
