We want an environmentally friendly way of killing the spider population on our boat dock. We don't want to use anything that can harm the Lake water and wildlife.
The most popular spider control product for use around water is Essentria IC3, because it is effective for spiders, kills most other insects (eliminating the spider's prey which will help keep new spiders from moving back into the area) and it safe to use around water. Most other insecticides are prohibited near the water because of the risk of contaminating the water and harming aquatic animals. You will need to repeat the application once a month through the warm season.
