Pest control method

1, spray some essential balm, and the bug will die.

There are also many mosquitoes in summer, and some essential oils are often prepared at home. The essential balm has a good mosquito killing effect without optical drive, and also has a good insecticidal effect.

2, the mosquito-repellent incense is burnt to ashes, and the pest control effect is good.

When there are many mosquitoes in summer, many places will also light mosquito-repellent incense to repel mosquitoes. The ash falling after mosquito-repellent incense burning is also a good insecticidal artifact. Flower lovers who like to grow flowers should not throw them away.
