Termites can be divided into three types: subterranean, dry-wood and damp-wood. Subterranean termites live in the ground and wood, dry-wood and damp-wood – only in wood.

Subterranean termites are not so widely spread as the others, but they also prefer soft climate with rains.

How to get rid of subterranean termites by yourself?

Create a “carton trap”. Take two cardboard sheets, wet them with water, place one on top and locate in the area of possible termites’ nest.

As soon as termites eat cellulose (in this case cardboard sheet) it will be a perfect trap for them. When termites fill in the sheets, take them away to a safe place and burn. Repeat as many times as you need.

Notice! This trap will not help you to solve the overall problem. This option is good if you want to destroy a couple of hundreds of termites. To get rid of all of them you have to combine this trap with other actions.

How to get rid of subterranean termites naturally? There is a bunch of effective ways but there is one which is the most popular and simple –try to use useful nematodes. Nematode is a type of small worms. These worms are natural parasites of garden pests, including termites. Nematodes need carrier body (for example termite nymph).

They connect with termites, and it takes 48 hours to kill them from the inside. Nematodes use termites’ body as a place for reproduction.

Nematodes are easy to be bought in the local garden store or via internet. Today there are 5 types of nematodes which can be sold.

If your ground temperature is higher than 15°С, nematodes should be used directly after purchase. If you don’t use them immediately, keep them in the fridge.

Place nematodes in the ground early in the morning or after the sunset: as ultraviolet is harmful for worms.

Orange oil usage

Orange oil is widely advertised as termites’ insecticide as it is less harmful to people. But the problem is that its usage is ineffective for subterranean termites.

Orange oil will not help you to deal with hidden colonies or those which are difficult to reach. Some companies choose it for its marketing and ecological appeal.

Even high concentration of orange oil will not save you from termites in long lasting periods. Furthermore, though orange oil is believed to be “green” solution for pests, it may cause serious problems to people who have problems with their breathing system or allergies.

Orange oil doesn’t have chemical transfer effect so it will kill only some termites, leaving the colony alive.

Before starting gas treatment you have to vacate the house; no food is allowed in rooms. All holes and cracks, space in windows and doors should be filled in with alabaster.

Ventilation shafts, boilers, fireplaces and etc. should be completely screwed up and closed. Rooms must be hermetically sealed. Gas treatment takes 3-5 days, after that rooms should be well air ventilated.
