Sabrina, please, get some good garden gloves so you can squish those things. If they have them in Italy, use plastic examination gloves that you might be able to buy at a pharmacy. Tweezers would work too. Oh, sprinkle salt on them! I live on the beach where my daylillies get salt in the air and salt in the well water we use. Salt in limited doses doesn't hurt daylilies. Maybe grind some sea salt on them.
As a personal note. We have a dear friend who illegally came to the US probably 10 yr ago from Naples, Italy. We met Pietro at an Italian restaurant he owned with his awful brother. They are twins and totally different. When we first met Pietro couldn't speak but a few words of english. Since then my husband helped him get medical follow up care for cancer that had been treated (brutally) in Italy. I won't mention what they cut off. Anyway. After that we helped him get a green card and now he's applying for his "permanent green card" that can help him get citizenship. I make huge platters of cookies/candy before Christmas for him and his staff (he owns 2 restaurants now). He won't let us pay for any visit we make to either of his places. He is the kindest, gentlest and caring man I have ever met. I love that guy! We keep helping, but wish he would let us pay for the food we eat. Forgetabboutit!
Hope you get some relief from the critters. They are everywhere! We have a variety of them in FL and they make life miserable!
