Frequently Asked Questions
What should I look for first?
Pale margin behind the head. Large reddish-brown roaches. A clear photograph and the location of activity can help with identification.
What conditions should I check?
Start with moist protected areas. Repair leaks and improve drainage.
Does seeing one mean there is an infestation?
A single sighting does not establish the extent of a problem. Repeated activity, developing young, nests, or other evidence help us determine what is happening.
