I again managed to find a caterpillar on an ornamental plant in front of my house, the caterpillar I found did not have any hairs or could be called a bald caterpillar, but I don't know whether this caterpillar is dangerous or not, but at that time I tried to touch it and it turned out that the texture of this caterpillar was very soft and its movements were very slow, I touched this caterpillar with my index finger but after that I didn't experience the slightest reaction, no itching and no swelling, but I still can't conclude whether this caterpillar is 100% safe or not. I usually find this caterpillar on plants that have a soft texture and this caterpillar is very detrimental because it can eat leaves, twigs or even the tree of the plant itself.
After I noticed and checked again, it turned out that there were more than 5 caterpillars like this on the plant. This could not be left any longer because these caterpillars would definitely destroy all the plants in front of my house. The only way out was to spray them with anti-pest medication so that the population of these caterpillars would decrease and not cause damage to my plants.
