Questions people ask
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
Are snap traps better than poison?
Indoors, usually yes. Traps let you confirm the catch and remove it. Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside.
How do I know if I have mice or rats?
Check the droppings. Mouse droppings are about the size of a rice grain. Rats also chew larger holes and sound heavier at night.
Are rats a bigger problem than mice?
Usually. Rats are bigger, chew more, and avoid new traps for days. Around Lake Havasu City, roof rats often nest in attics, so check the roofline too.
Will rodent control harm my pets?
It shouldn't. Traps go where pets can't reach. Bait stations are locked. Tell the company about your pets before they start.
How many homes have a full rodent infestation?
In the National Pest Management Association's (NPMA) September 2022 Harris Poll of more than 1,300 U.S. homeowners, 14% reported a multiple-rodent infestation over their lifetime, far fewer than the 37% who recalled a single animal.
