When ants go to that place, it is estimated that the old birthday girl is poisoned-she is impatient and wants to die! Ha ha! First, water the cracks in the wall with boiling water, then spray insecticide, and finally put a lid on the toilet seat, otherwise ants will climb up from the sewer, which is disgusting. Through the investigation and statistics of common pests in families, there are mainly four kinds of ants, namely, small yellow house ant, big head ant, Rockwell community ant and smelly ant. Through the analysis of the characteristics of these four ants, although they are far less harmful than cockroaches and flies, they are still hidden dangers at home. Therefore, according to their characteristics of digging holes in the active path and leaving special chemical odor, 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.
