What's with the little yellow ants at home?

There are ants in the wall or on the balcony. Go to the store or farmer's market that sells crop seeds or flowers for consultation. There are special drugs, one or two yuan a pack, and the effect is very good, or the kind of spray that kills cockroaches in cracks in the wall may emerge one after another, but the effect is not as good as medicine. Through the investigation and statistics of common pests in families, there are mainly four kinds of ants: yellow ant, big ant, Rockwell road ant and smelly ant. Although it is far less harmful than cockroaches and flies. It is still a hidden danger to the family. Therefore, according to the characteristics of digging holes and leaving special chemical odor on its activity path, the following methods can be adopted to remove them:

○ Wet cloth wiping:

If one or more rows of ants are found to be active, they can be wiped off with a wet cloth and drowned in a basin filled with washing powder water;

○ Washing powder ditch barrier:

Because ants will drown as soon as they enter the washing powder, you can protect an area in this way;

A flood:

That is to say, watering the nest is more suitable for ants to nest in flowerpots.

○ Chemical control:

Dust: Inhaled dust such as silicic acid (silica) powder is usually used to make ants die of lack of water;

Mixture of fenvalerate silicate powder:

This method is an improvement on the previous method, which can shorten the killing time, but it should avoid inhaling powder or dust indoors.

Spraying chemicals around the nest mouth and on the ant path can directly contact and kill ants.

This method is easy to cause environmental pollution and resistance. Commonly used drugs are as follows:

Spraying more than 90% trichlorfon stock solution 500- 1000 times;

50% DDVP EC or 80% DDVP EC 1000- 1500 times, 2000-3000 times;

0. 1% pyrethroid kerosene solvent spray, etc.

These methods are effective and quick, but they are not thorough, difficult to eradicate and easy to cause environmental pollution and drug resistance.

○ Poison bait:

Poison bait is a mixture of chemicals and food bait that ants like to eat. According to the mating behavior of ants, as long as a worker ant does not die in a short time, causing other individuals to die, it can bring poison bait into the nest. The time of death is usually within seven days, but the ant pupae may survive without eating, which causes the incomplete extermination of ants.

○ Juvenile hormone analogue bait:

That is to say, juvenile hormone analogues, such as floxuridine and methoxyprene, are mixed in the bait, and the hormone concentration is generally 0.6% ~ 1.5% of the weight of the bait. At present, synergist is being developed and juvenile hormone analogues are added to make this method more perfect.
