One of the most effective prevention measures is exclusion - performing structural maintenance to close potential entry points found during initial inspection. Treating for pest without considering prevention of the future issue is a waste of time. Repeated infestation must be prevented whenever possible.
There are two well-know types of crickets - field crickets and house crickets. Field crickets are usually dark to black in color. House crickets are much lighter - tan to light brown in color. They will live in and around the houses.
We typically receive many calls about crickets in Fall - by that time adults are entering the buildings looking for a warm shelter to spend the winter months. The biggest issues with crickets seems to be the noise they produce - crickets make this awful and repetitive noise outside and inside your home.
