Default Caterpillars

Hi Guys, (almost new to lasers)
I just bought the o-like 445 nm 1 Watt blue laser with the intention to do a special project. I need to focus the beam at approx 40-50 feet so intense that woven tissue can be engrave/burned.
Burning at 1-8 feet is no problem at all with the current configuration.
Is this possible, and can you give me an advice what lense to use or how to experiment? (with protective glasses of course)
in advance, John (Netherlands)

Default Re: Caterpillars

it would take more than 1 real watt and additional optics to get a 445 to burn/engrave at 50 feet. i don't think i have ever heard of any hobby level laser doing engraving etching at that distance. the focal point is usually close to the aperature. at that distance you will be able to slowly burn a hole through fabric, maybe. you will be able to pop a ballon. but thats about it.

What on earth are you doing? It sounds like something you shouldn't be doing.

At any rate, expand the beam and use some long focal length lenses.

What does this have to do with caterpillars?
And how do you mean woven tissues? Like kleenex?

Might be able to be done with a good beam expander but thats going to cost a lot of money. I hope you have good intentions when using one of the most powerful and dangerous handheld lasers made.

Default Re: Caterpillars

Ok, thanks guys, so to conclude I should experiment with a beam expander and long focal lenses. To zoom in the subject: in the oak trees around my house, and not only my house but almost everywhere in the direct environment live groups of caterpillars. I don't know the right english word, but the look like this:


These guys have burning hairs (about 200.000 to 300.000,not the visible one's), and in the months May, June and July (our summer) they dump these hairs. This is sometimes dangerous, people can become blind when hit by groups of hairs, but also when hit, your skin becomes iritated for weeks. Its a plague in the northern countries in europe.
Their nests are spun/woven and look like tissue. They only live in oak trees.
You now know the background of the question.

Oh wow, that sucks. I'm not sure a laser is the right solution though. If it were me, I might use a jet of water. Dunno.

I don't think a 1-2W laser is enough for the job. I would try a propane torch.

Isn't there some way to protect your selfs from them? Don't you think that the simple fact that you have such a population that it is tied into the surrounding ecosystem? Isn't there something that eats them that you could just bring into your area to keep them down? Something in your area has to eat them and there are way to attract that type of animal to keep them away from you homes? I'm sure there would be a easier solution than a laser.

What were you plaining on doing going around for 3 month of every year Directly burning them 1 by 1? Just sounds a little silly to me....

Default Re: Caterpillars

I recommend Windex. No, srsly... glass cleaner has some solvents that kill insects within a minute or so. I keep a bottle on my porch for when the yellow jackets come poking around. Isopropanol and other solvents work well, too. Admittedly, a spraybottle doesn't have quite the range of a laser. The dollar store carries it for... you'll never guess how much. I'll give you a hint: It's cheaper than a laser.

Default Re: Caterpillars

I agree that a blowtorch (or some toxic liquid [liquid Spinosad]) is a good way to control the population in your local area (around your house), but really you need some sort of "pest control" Caterpillar Predator:
---Caterpillar Parasites
(Trichogramma)

Amazing Caterpillar Parasites (Trichogramma species) control over 200 species of Caterpillars, making them the most popular bio-control in the world. They're so tiny (1/50 of an inch from wingtip to wingtip) you probably won't even see them. They work by laying their eggs inside moth or butterfly eggs so that, instead of a new generation of caterpillars, another parasite generation hatches out and goes on to repeat the cycle.

Application: For best results, Caterpillar parasites should be released when Pest Moths or their Caterpillars are first seen, and further releases continued weekly or bi-weekly until Caterpillars are no longer present. Use 3,000 to 50,000 per acre, depending on the level of infestation. Caterpillar Parasites come as eggs ready to hatch. 3,000 eggs are glued to a small piece of cardboard. Placed around the garden, they'll hatch and breed from there.

Shades of Green
^^ Isn't That what I Said?

A Predator will be most Effective. Something that eats them down 24/7 and will be able to Populate depending on the Food Sources amount in Your Area. They Will Eat and Destroy a Good Portion of the Population. And make sure that Either the Main Predator Also Eats Eggs and/or Adults Or get Another to release in your area to Eat them as well. But Make sure Everything You Add to the Area is Common to your Location And Common to the Area So That you Don't Cause Other Problems.

Default Re: Caterpillars

A blowtorch will also apply a small force on your target. And depending on the mass of your particular bug or caterpiller, he may blow away before he's properly been scorched.

I recommend the spray alternative also. Windex sounds good, but perhaps if you added some acetone to a spray bottle, that may be just a bit better! The more solvent the better!

Hee guys,
thanks for all the good advices.
However there are some limits to the stuffs used.
1. chemicals: how to spray them in oak trees of 30-50 feet high? And don't they destroy more than the caterpillars.
2. torch: i will probably set the tree on fire. It will kill the caterpillars, but probably also the trees, and maybe more.
3. wasps: I am a bit anxious to import these wasps to Europe, (if allowed) because don't know the consequences of this.

My main goal was to invent something that would kill those nasty basterds.

Actually someone has invented already something like this for mosquitos:

Why not use this for caterpillars, should be much easier cause the're slower.

Default Re: Caterpillars

You need something against the processierups? A laser would be possible but usually the trees are in public locations which makes safety a problem. Getting a good lens shouldn't be that hard. A pulsed CO2 would be relatively safe, but CW may also be possible. Getting the right lens would then be more difficult. If a CO2 laser has a good beam profile like other gas lasers it won't be that bad though.
