Bug control question

I am having two bug problems and would love any suggestions that do not involve dangerous chemicals.

One is sap beetles,... They are especially bad on and around my bee hive. Would love any suggestions on how to get rid of them without harming bees

Second is Japanese beetles on my young cherry trees. The trees are only about 5 ft tall, so easy to manage this year. I tried sprinkling with diamatacoeous earth, but not sure if that will control Japanese beetles.


Thanks...

Ps: I have some chickens, so any trap methods that I could then feed these bugs to the chickens would be great,

We are in Japanese beetle heaven where I live.

This year - for the first time - I have turkeys loose underneath the muscadine vines. On an average year the beetles will decimate the muscadine leaves but this year very little damage.

So.... I put some netting around my blackberry/horseradish patch and turned the chickens loose in there - now with in a week the beetle damage is minimal. I won't be able to let the chickens stay there long as they will eat the horseradish leaves themselves eventually but they have done a good job fending off the beetles and who knows what else that was hanging out in there.

I have not ever had total success in combating japanese beetles and finally just got rid of all of my hybrid tea roses just because of that. But I am at about 6 years with no chemicals here and I have seen the population diminish. I have placed two praying mantis egg cases here (last year). I don't see the praying mantis but my husband says that he has. Also I keep frog and lizard habitats - we have TONS of lizards and this year an explosion of frogs so I think that helps as well.

I use the pump sprayer with boric acid and a little soap.

I do all the edges of the buildings for termites every couple years, so is easy to use on the heavily attacked stuff.

all the predators are hatched out around here right now, only thing still attacking is the dang Texas Glass grasshoppers. They even attack and kill oleander and rosemary!
