How they work: four steps, no mystery

Identify first

Carpenter ants and house ants need different treatments. They find out which before they treat.

Treat with the least

Targeted application using the least-impact product that will do the job. Botanical options on request.

Seal them out

Trapping brings rodent numbers down. Exclusion is what stops them coming back.

Follow up

Bed bug jobs include mandatory follow-up visits, so the problem is actually gone.

Delaware pest questions

Who should I call for mosquitoes, ticks, or pests in the house?

Mosquito & Pest Authority handles both. Anything in or around the house — termites, ants, mice, bed bugs, wildlife — and mosquitoes, ticks, and other yard pests. Not sure? Snap a photo with the Bug ID tool and we’ll route you.

How often does Mosquito & Pest Authority treat my yard?

Every 21 days through the season, timed to the mosquito life cycle. If mosquitoes come back between visits, they re-treat at no extra charge.

Do I need a termite inspection to sell my house?

Lenders commonly ask for an NPMA-33 wood-destroying insect (WDI) report before a Delaware closing. Mosquito & Pest Authority writes them.

Are the treatments safe for my kids and pets?

Mosquito & Pest Authority uses EPA-registered products applied per label. For yard work, kids and pets can go back out once it dries, and an all-natural option is available. For pests in the house, they use the least-impact product that will do the job, with botanical options on request.

Is the AI bug identifier accurate?

It’s a strong first step, and it tells you how confident it is. For look-alikes like termites vs. flying ants, it will always recommend a professional inspection.
