beetles are demolishing my roses?

Question

Never had this before in 11 years in this garden, beetles dark brown with green top are eating all the petals on my roses particularly yellow and white roses. Am desperate so any suggestions?

Answer 1

Sounds like Japanese beetles. Spray with insecticidal soaps, rotenone or pyrethrin. Also diazinon, Dursban, carbaryl or Orthene. Handle with care. Set out beetle traps which will attract adults from all over. Don't put the traps too close to the roses or it'll make things worse. Putting them downwind from the roses works best.
Also check with the local agricultural extension office. Look in the phone book under local gov.

Answer 2

Pray for drought. in any different case, there is not any longer lots you're able to do. particular, there are beetle traps, yet with the aid of fact in user-friendly terms a share of beetles ever fall into the catch, and the catch brings in a good number of beetles, you're in all probability to have extra beetles around with the traps than with out them. there are particularly some issues you could positioned on your backyard to kill grubs interior the spring, yet they are often high priced, and ineffective with the aid of fact the grubs on your neibor's backyard with basically come on your roses truly (in different words, an entire neigborhood could ought to try this to make it clever). you additionally can kill them with Sevien, yet regrettably which will additionally kill each and all of the bugs that are sturdy on your roses (at the same time with woman bugs who munch on the aphids for you) and you ought to save reapplying with each and each new wave of beetles. the only sturdy way is to basically hand-%. them of the rose. All you ought to do is get a pail of soapy water, place it under the beetle, and the two shake him off the rose into the pail, or basically touch him (his organic defence is to drop to the floor... or thus, into your pail). The beetles basically isn't waiting to flee the soapy water and could drowd. BTW, I reported pray for drought with the aid of fact they choose moisture interior the spring at the same time as they are grub. If there's a drought interior the spring, there'll be some distance fewer beetles that summer season.
