While pests have developed over the millions of years, it took only about 50 for science to keep up the pace. Today, with increasing environmental concerns, non-toxic pest control options that are harmless to humans, non-pest species, and the soil and water resources are becoming a popular alternative to traditional aggressive chemical products.

Carpenter Ants

They are considered a pest because of their habit of tunneling inside wood and rigid foam insulation. Unlike termites, carpenter ants do not feed on wood, but use it solely for building the nest. They can be especially dangerous if they infest your house foundation.

  • Control measures – treat exposed parts of wooden structure with Bora Care against moisture accumulation. If you notice ant damage, repair it and prevent them from reaching that spot again. Deny them nesting areas by excavating stumps and taking care of injured trees. Inspect firewood before taking it inside. As these ants love trees, they will likely use branches to reach your roof. Prune all branches that touch the house. Discovered nests should be treated with boric acid.

 Colonies of these hard-working pest insects are so feared by homeowners that you can often hear that only a full scale extermination procedure gives results. However, homeowners forget that these operations are costly, and that not only these pesticides are harmful for the environments, but can also present a risk to the inhabitants.

  • Control measures – Termites feed on wood, but cannot live in it for long. Actually they live in a nest that is often underground and commute to your structure only to feed. By attacking the nest or shelter tubes that they use to enter your structure with vinegar, you can effectively stop them in tracks. If needed, apply the vinegar few more times. Another green way of dealing with them steps into the field of biological warfare. Nematodes are microscopic worms that can be bought in containers and poured as a water solution into the nest or shelter tubes. They effectively kill termites by infecting them.



 Although there are certain benefits from wasps, like pollination and killing other pests, there are much more reasons not to leave them be. For example, if you have a small backyard, or their nest is built low along your path, it would be really hard not to disturb them. The pesticides that are used in spray cans are strong enough to kill your pet if it eats a dead wasp.

  • Control Measures – the easiest way to keep them off is to hang a fake paper nest. Although it doesn’t work every time, wasps are territorial and won’t get into another gang’s area. There are all kinds of wasp traps and you can make some yourself. The trick is to use savory bait, like tuna or a piece of sausage as sweet bait will attract honeybees, too. You can find eco pest control products against wasps such as EcoPCO JET-X – Wasp & Hornet Jet Aerosol which are as effective as heavy duty chemical products but they are made of 100% natural ingredients.

Green ways of dealing with pests vary from prevention, keeping them at bay, to natural bait traps and non-toxic spray products. They are best used combined, respective to the infestation level.
