The exterior of my house is littered with cobwebs and most of them are in places like the soffit and other areas that are hard to reach. I'm even seeing small bugs and cobwebs along the hardie boards.

When I get up close to other houses in my neighorhood, it doesn't look like they're struggling with the same thing so it makes me wonder what I'm doing.

I've wondered if it's pest control related but I've never seen any pest guy spray up high in the soffit and eaves. I've generally done my own pest control using Bifen IT but will admit it's been a hot minute.

Any thoughts as to what I could be doing differently?

Spray the Bifen up to the soffits. That's what I do and no issue.

I think a lot of the pest guys will use a brush on a telescoping pole to get the cobwebs down from the soffits as well.

Do you spray all the exterior walls of the house as well? Just seems like I have bugs and random black marks all over the place

Outside: I use Demon WP. Usually spray around the house two feet up the foundation and two feet down from the foundation into the yard. Spray up the house corners grass to roof, around doors and windows, corners of eve and walls, and around access points (outside plugs, etc)
