How Professional Fall Invader Control Works
Good fall invader control starts with a look at where bugs gather and how they get in.
At Bug Shockers Pest Control, we start by finding where the bugs gather.
We check sunny walls, windows, doors, and the roofline.
Then we choose the right treatment for your property.
We often treat the outside of the home before the main wave arrives.
We explain what we find in plain language, so you know what to expect.
Can Fall Invader Problems Be Prevented?
You can lower the risk, but no yard is ever fully free of fall invaders.
​
Seal gaps around windows, doors, vents, and siding in late summer.
​
Repair screens and weather stripping.
​
Vacuum bugs inside instead of crushing them.
