Final Words

One final trick for those with large outdoor yard or lawn area is to mow regularly. Researchers have found that Fleas and Ticks prefer areas under the trees with many fallen leaves, and in the bushes where everywhere is tall weeds and grass that trap moist.

As with most pest situations, the most effective way to eliminate Flea and Ticks in the yard or in the outdoor area is to find the root of it; and work from there.
