Spider Extermination in Fresno

Spider ControlDid you know there are over 30 different types of spiders in the Central Valley, and some can lay up to 1,000 eggs in their lifetime?

One of the most common misconceptions regarding spider extermination in Fresno is that creating a barrier is the best way to keep spiders away. This is only step one to an effective spider treatment. With spiders’ long legs, they can often walk over many types of pest barriers without adverse effects.

Spider Treatment 

A good spider treatment starts with creating a long-term barrier. The second step is to broadcast treatment in their hiding places, such as inside bushes. It is also recommended that this treatment be done with an organic spray if any kids or pets use the yard. The broadcast spray should start at the fence line and moves inward to the structure. All the bushes, lawns, and flower beds should be treated. Most companies have stopped including a power spray. It is essential to treat spiders where they hide and remove the spider’s food (Bugs) source.
