Trap cockroaches with egg yolk
Use 1 egg yolk mixed with 25-40g of boric acid powder, which you can buy at a veterinary store, to make a trap for cockroaches. Then, mix the two ingredients together until the mixture becomes thick. Divide the mixture into small round balls, about the size of a tennis ball.
If you suspect there are cockroaches in certain areas of your house, place these balls there. It could be in hidden corners, shelves, cabinets, etc. When cockroaches smell the egg, they will immediately come to nibble on it. The boric acid powder will swell and destroy their digestive system, causing them to die.
Trap cockroaches with baking soda
First, mix 2 tablespoons of baking soda with sugar in a 1:1 ratio. Put the cockroach bait in a tall jar with a mouth big enough for the cockroaches to crawl in. Then, you can apply a little cooking oil inside the mouth of the jar to prevent them from crawling back out. This mixture is harmless to dogs and cats but lethal to cockroaches. This is because cockroaches have a lot of acid in their stomachs to digest harmful food. When the acid in their bodies reacts with baking soda, it produces gas, causing the cockroaches’ bellies to expand and eventually kill them.
