There are many species of termites that harm trees. The main types are: neoterms, wood-nosed termites, sand-heap termites, proto-termites, tree termites, loose termites, ground termites, house termites and large termites. Because most species of termites are inseparable from the soil, it is most important to treat termites with soil.

Pine termites and sand-heap termites are also common in trees. The main pests of fruit trees are black-winged termites, termites and yellow-winged termites. Forest termites mainly harm trees and houses in forest areas. Termites are extremely harmful to fir plantations. Termites are harmful to gardens, and greening trees along the streets is more common. Ant-strewn tree trunks often serve as breeding grounds for termites to invade nearby buildings. Maple poplar, maple incense, plane tree, plane tree and other tree species are seriously damaged. The main measures taken by termite control technicians to control forest termites are:
1. Treat the soil with drugs, and the treatment thickness is similar to the root depth of the seedlings. Poison mud dipped in roots, mainly for newly planted seedlings or precious tree species. Termite control company uses 0.1% to 0.5% of cypermethrin emulsion, yellow mud and phosphate fertilizer to mix evenly, and then use poisonous mud to dip the seedling roots, dry a little and plant to prevent termite infestation.
2. For newly planted seedlings and precious tree species, add yellow mud and phosphate fertilizer containing termite control agent, mix well, dip the roots of the seedlings with poisonous mud, and then plant after drying slightly. This method can effectively prevent termites from approaching the tree when termite populations are large in green areas or transplanted tree species are very precious, and can be treated with chemicals that have a long validity period and have an avoidant effect in the soil.
3. Control of woodland termites, it is impossible to treat the trees one by one, it is best to use booby traps. Experts from the termite control company said: The bait method is to use the bait that termites like to eat to make a certain amount of "booby trap bags" or "booby trap blocks", and then put it in the green space, so that the termites can be poisoned. The common recipe for termite killing bait is mostly fibrous plants that termites like to eat.
The "bait trap method" traps termites, and the location of the drug delivery point can be randomly determined whether there are signs of termite activity. It can also be placed on tree surfaces and on the ground where there are signs of termite activity or freshness. For those placed on the ground, you can shovel 5 to 10 cm of soil, lay a layer of weeds, put a bag of poisonous bait, and then cover it with a layer of grass, seal the soil, maintain the temperature and humidity in the pile, and let the termites eat the poisonous bait to eliminate termites.
The advantage of "booby-trap method to control termites" is that it is simple to apply, no inspection, no application. However, the disadvantage is that after these booby traps are put into use, they will have a killing effect when they are eaten by termites, and it will be wasted if they do not eat. At the same time, the packaging will not be eaten by termites for a short time after it is put into use, that is, the trap packaging is wet and moldy, and the termites no longer eat, so that the termites cannot be killed. In addition, due to the interference of a large amount of food in the green area, the termite colony chooses to bait inconspicuously, and the effect of booby-trapping termites is poor.
4. Clear termite breeding grounds for afforestation, especially on barren hillsides and plots with large numbers of stumps and dead branches. Before afforestation, the soil is deeply ploughed to destroy the nest, and then termite control drugs such as 1%-2% chlordane or 5%-10% sodium arsenite are formulated, and the professional technology of the termite control company is used for treatment. This can prevent the route of underground termites in advance, so as to achieve a good termite prevention effect.
