The harm of indoor ants to home is often overlooked. After investigation, indoor ants mainly include small yellow house ants, big head ants, stone road social ants, smelly ants, etc., and often nest in roadside, corners and cracks in walls. The main ways of harm are stealing food, biting people and spreading bacteria. According to their activity characteristics, some physical and chemical methods can be used to prevent and control them, such as blocking the activity route and blocking the nest. If possible, biological hormones can also be used for prevention and treatment.
Foreword:
Ants belong to Arthropoda, Insecta and Hymenoptera. Although there is only one family (Formicidae), there are more than 360 genera under it, estimated to be about 14000 species, and there are about 300 species in China. They are widely distributed, from desert to forest, from tropical to cold zone, from plain to mountain. The diet of ants is very complicated, and all kinds of animal and plant carcasses and organic residues can become.
With the rapid development of urban construction in China, the living environment of ants has changed greatly and gradually adapted to the urban environment with dense buildings and dense population. They often invade indoor foraging and nesting. Because indoor ants can pollute food, destroy buildings, spread bacteria and bite people, which will do some harm to human life. In order to prevent and control this kind of harm better, we must know the species and habits of indoor ants, and then put forward some effective measures according to the specific situation.
Materials and methods:
According to the investigation and statistics of common pests in families, there are mainly four kinds of ants: yellow ant, big head ant, Rockwell social ant and smelly ant.
According to the relevant data, the Latin names, ant colony types, body characteristics, distribution of each group, activity places and damage modes of these four ants are summarized as follows:
The front and side views of the yellow ant and the big-headed soldier ant are as follows:

By analyzing the characteristics of these four ants, although their harm is far less than that of cockroaches, flies and so on. They are still a hidden danger 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:
Physical prevention and control:
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;
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 (silicon dioxide) powder is usually used to make ants die of lack of water;
Fenvalerate silicate powder mixture:
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 ant 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.
Life tips:
After the eggshell is ground into powder by burning coke, it can be scattered in the corner or near the ant nest to kill ants. There are ants in the closet. You can put some vegetables such as parsley and celery to drive away the ants. Put some walnut leaves, tobacco and peppers in places where ants often haunt, which can drive away ants.
