Whenever there is an infestation of termites or other such creatures it may be time to call in an exterminator to spray the property to safeguard it. Even mosquito control will be able to spray the garden and surrounding areas so that people are not bothered by these biting insects. But perhaps the worst problem that people can have is with termites which actually eat away at a building until it could become unsafe.
There are several things people can do to stop some flying insects from laying eggs in the vicinity. For example, keeping any water feature in the garden clean and with running water means that the creatures have nowhere to lay their eggs. If there is any stagnant water, even in a bucket, they will have somewhere to lay eggs which will hatch in a short while. Long grasses too are the areas where eggs are laid so making sure that the garden has no wild patches is a good way to cut down on insect invasion.
As for termites, well these creatures will tunnel underground over vast distances and they may not show themselves until they have to traverse immovable objects. They then build earth tunnels to move through since they cannot expose their soft bodies to the air. To check to see if an infestation is active, try wiping away some of the earth tube like structures and see how quickly they are rebuilt. If they reappear in a day or so, then the colony is very active indeed.
Termites are very funny creatures in that once they have found a good food source, and that could be anything from expensive furniture to roof beams in a house, they will leave a scent trail to let other termites know where the food is. Of course, people will only realize that something is wrong when wood begins to sound hollow or sand like dust is noticed around furniture. The termites are after the cellulose in the wood and they will not stop eating until there is no wood left to eat.
The usual way of ridding an area of termites is to dig a deep trench all around the affected building. Then, toxic chemicals are poured into the ditch to make sure that this forms a chemical barrier that the termite cannot cross. Although this is rather a drastic approach to getting rid of something so small, the destruction they cause can never be underestimated,
There are newer methods of ridding a home of termites and this includes sinking feeding tubes at regular intervals all around a building. The poisoned bait is laid into each tube and the termites are attracted to it. Once they have eaten the poisoned bait, they take some back to the colony for others to eat and eventually the queen will be killed. Once she is dead then the whole nest will die off because they just cannot survive without the queen in the colony. This method is far less disruptive and surely helps to protect ancient monuments too.
