The comfortable temperature for an American cockroach is about 84 degrees Fahrenheit. As outdoor temperatures cool, American cockroaches may move inward. They enter through entry points such as air ducts, around utility pipes, small cracks and crevices, sewer connections, and under doors. Cockroaches will eat just about anything and if you have pet food outside, leftover barbecue food, or orchards and fruit trees, cockroaches will be dragged into your garden.
And the ultimate reason to see cockroaches outdoors at night is that cockroaches are nocturnal creatures. We can also advise you on pest exclusion measures you can take both outdoors and indoors to keep cockroaches and other outdoor pests away. If you have a cockroach problem or if you want to start a prevention program before it becomes a problem, call a professional pest control company that can provide you with a customized pest control program using only the most innovative and advanced pest control products and equipment available. But the most effective thing you can do to prevent cockroaches from invading is to partner with a professional pest control company.
In the case of American cockroaches, for example, you will want to have external controls in August or soon after, since cockroaches will try to enter from August to November.
