y****2 发帖数: 11909 | 1 如果是的话,用这个neem oil比较安全:
Another way of naturally killing leaf miners is to use neem oil. This
insecticidal oil affects the leaf miner’s natural life cycle and will
reduce the number of larva that become adults and thus the number of eggs
that the adults will lay. While neem oil is not an immediate way how to kill
leaf miners, it is a natural way to treat these pests.

浩荡荡地爬上了桌,看见后浑身起JPGD,然后去home depot买了杀蚂蚁的药,听说蚂蚁
不喜醋,于是用醋擦桌,后来蚂蚁没再进来过。
不过后院蚂蚁很多,时不时地有叶子被吃,不知道是蚂蚁的过错还是别的虫子。打算开
荒种菜,把草皮翻了堆在了一起,有天翻了翻堆土,里面几百个蚂蚁,就用醋对水浇了
下去,不得了,蚂蚁慌慌张张集体搬家,来来回回的忙个不停,我就看热闹,用相机拍
照片,拍不下来,只好用摄像,但见每只蚂蚁都背个小小的白色的蚂蚁卵,这是baby吧
,几小时候后蚂蚁的家搬完了,堆土里一只蚂蚁也不见了。真干净。
看来蚂蚁不喜欢醋,但醋不杀蚂蚁,我不知道蚂蚁该不该杀,古狗后看了更糊涂,好像
有的蚂蚁不碍事,有的蚂蚁也害庄稼。
下面是古狗来的。

Uses for Neem Oil
Neem oil can be used to treat a number of garden ailments, including:
Insects: Neem oil kills or repels many harmful insects and mites,
including aphids, whiteflies, snails, nematodes, mealybugs, cabbage worms,
gnats, moths, cockroaches, flies, termites, mosquitoes, and scale. It kills
some bugs outright, attacks the larvae of others, and repels plant munchers
with its bitter taste. |

To treat a flea- infested cat, a 3-step approach is recommended:
1. Treat with Capstar, a pill which kills fleas within an hour (lasts
only 24 hr). We use dog size Capstar (>25 lb). The dose is ¼ pill for
adults, and 1/8 pill for kittens.
2. Wait 30-60 minutes, then bathe the cat using a mild shampoo (NOT a “
flea” shampoo) to remove dead fleas and larvae.

"Nearly all puppies, 98%, are born with roundworms from infection by their
mother. Even if the puppies' mother tested negative for roundworms before
she was pregnant, roundworms are still passed, due to the fact that
roundworm larvae lay dormant in intestinal tissue from her own infection as
a puppy. " |

b*****2 发帖数: 11103 | 21 What Should I Feed This Baby ?
Despite the varied feeding habits of adult perching birds, all baby birds
require similar nutrients to grow and thrive. Perching birds that normally
feed on high-protein insects, feed these to their young. But perching birds
that normally feed on seeds, fruits and berries also feed insects to their
young until they leave the nest. This is because seeds, fruits and berries
do not have enough protein content to sustain the enormous growth rate of
baby birds.
