Not generally. Mosquitoes do not usually seek shelter in the grass. Our goal in doing a pre-spray walk of the property is to seek out the “hot spots” where mosquitoes will be hiding. The most common areas to find mosquitoes during the day include: the underside of the leaves of dense/shrubby plants, under decks and in damp shady areas of the property. In fact we do recommend that you keep your grass short during the mosquito season.
In some cases such as special events like weddings and large outdoor parties, we will spray the grass where your guests will be. We may also spray the grass to if you’ve asked us to treat a tick problem.
