To Milk Spore, or NOT to Milk Spore?

Hi, I have a terrible Japanese Beetle problem (zone 7a). Have any of you tried milk spores on your lawn to get rid of their eggs? If so, did it work? How long did it take until you noticed a difference in the amount of beetles?

Thanks for any feedback! :)

The milky spore takes care of their grubs, so it will have no impact on the beetles that you have right now. But it can help with next year's "crop". However, if you have a relatively small property and lots of neighbors who are not using milky spore, you won't eliminate the problem since their grubs will turn into beetles which can fly into your yard just as easy as into theirs, but every little bit of population reduction you can do will help (and if your neighbors are gardeners, you might be able to talk them into applying milky spore too)

It can only help not hurt! You will not totally get rid of them though. need to do my lawn as well. The stuff isn't cheap though...

Agree with ecrane3 and tommyr2006. Last year my yard was overwhelmed with J Beetles. I bought one can of milky spore. I placed into a spice shaker type jar and sprinkled through out my flower beds. The good thing about milky spore is that once a grub ingests the spore and dies, it serves to increase and spread the milky spore through the soil. Today is the first time I have seen JB in my yard this year and I killed 5 through the day. I am all for what ever decreases the population of JB!

I have a prob with Japanese Beetles as well. Every leaf on EVERY rose bush I have is full of holes (including the brand new blooms). Does anyone know how to make a "spray" that I can use to kill the adults?

Mindalina, if I can catch them on the rose plant, I spray them with soap spray (I bought mine from Lowes, there are many brands). I think this kills them, but my problem is that they keep coming back and I can't reasonably sit vigil at my rose plants all day and night. Also, if you can grab them if you see them and throw them in a bucket of soapy water or shake them into the bush into the soapy water this will kill them too. There are chemical sprays that will kill the JB if you contact them with the spray, however, I have small children and do not want to use chemical sprays in the garden (plus, trying to be kind of green!) The organic spray I have (which is mostly neem oil) does not work on beetles, and does not profess to do so either. Most mornings, I will go and spray the rose plants with a strong stream of water on the stems/leaves(jet setting on my hose nozzel) and then a semi-strong stream on the rose flowers (so you don't lose too many petals) which kicks some of them off, but they will inevitably come back for more delictable roses...so, I will try the milk spores, hope they work, good luck, I know what you are going through! Also, I must add that I'm a newbie gardener so more experienced gardeners might have some other (better) advice!

Thanks for the advice everyone! What the heck, it can't hurt I guess. I'll probably apply in the Fall after the August drought season is over. I'll keep you updated on the progress :)
