Leafhoppers

[Zalaster]

My cascades are doing awesome this year, topping 22 feet now. They are starting to produce cones now. As luck would have it, the leafhoppers have just found them too. Do they attack cones too? I can live with some chewed up leaves as long as they leave the cones alone.

If I were you I'd use a Pyrethrin spray. It is a great contact killer but degrades very quickly. In most cases in just a few hours.

Or mix dish soap at a rate of 1 oz per gallon into a garden sprayer.

As the hoper chews he chokes on the soap that suffocates him.

Or that. ^^^^^^^^^^^^^^^^^^^^^^ At least you can do that today.

-1 Pyrethrins are used in many varieties of insecticide, fogging products and in some pet products. Care should be taken when using this substance around humans and animals. Overdose and toxicity can result in a variety of symptoms, especially in pets, including drooling, lethargy, muscle tremors, vomiting, seizures and death.[5] Toxicity symptoms in humans include asthmatic breathing, sneezing, nasal stuffiness, headache, nausea, incoordination, tremors, convulsions, facial flushing and swelling, and burning and itching sensation.[6]

Pyrethrins are extremely toxic to aquatic life, such as bluegill and lake trout while it is slightly toxic to bird species, such as mallards. Toxicity increases with higher water temperatures and acidity. Natural pyrethrins are highly fat soluble, but are easily degraded and thus do not accumulate in the body. These compounds are also toxic to bees.[6]

I've had the headaches from that crap !

Yep!! there's the good, the bad and the ugly with any insecticide. If you're careful and use it as directed it should be fine. I use it and wear a face mask so I don't breath it in.
