スズメバチは、甘い香料や黒色に反応すると云われているので、無香料の洗濯石鹸で洗った、明るい色の服を着て、フィールドに出るようにしました。
その効果は明確ではありませんが、以前ほどスズメバチは、私に関心を示さなくなったようです。でも、油断は禁物です。
慣れると分からなくなりますが、香料入りの洗剤の匂いは相当強いです。
There are a lot of hornets in the field than usual, because it's very hot this summer. A hornet often makes a circle around me when I walk in fields, so I feel scary.
Both sweet fragrance and a black-color will excite a hornet, so when I go out to the fields, I wear clothes in the bright color washed with a fragrance-free laundry soap by habit.
The effect is not clear, but a hornet doesn't seem to have interest to me like before. I can't relax yet.
The ordinary laundry soap contains a strong-smelling substance. We don't notice the smell, if we get used to it.
