Why do ants keep coming back after I spray?

Over-the-counter sprays kill visible ants but do not reach the colony. If the nest is inside a wall, under your home, or on a neighboring property, surface sprays are a temporary fix. Brennan technicians locate the colony source and treat it directly so the infestation does not return.

How do I know if I have carpenter ants?

Carpenter ants are common on Long Island and often leave behind small piles of sawdust near wood they are excavating. They are larger than most ant species and may be seen near window frames, door frames, or decking. Winged carpenter ants are sometimes mistaken for termite swarmers. A Brennan inspection will identify the species and the nest location.

Are winged ants the same as termites?

No. Winged ants and termite swarmers are often confused because both appear in spring. The key differences are body shape and antenna: ants have a pinched waist and bent antennae, while termites have a straight waist and straight antennae. If you are unsure, Brennan will identify what you have at no charge.

These little pests can show up in the spring, summer, fall, and even winter. They love our homes, especially our kitchens and bathrooms because of food and water, but they also may just be looking for shelter.

Why Ants Keep Coming Back After You Spray

We at Brennan have even found ant colonies in vacant homes with no food or running water. Spraying the home with a can of pesticide is only a band-aid and can leave your home covered in dangerous chemicals.

These sprays do not get to the root of the problem because they only kill the ants you see, they never reach the nest. These nests can be in your walls, under your home, or even in your neighbors property.

Carpenter ants are quite common on Long Island and can chew through the wood of our homes much like termites. They build homes inside of the wood leaving sawdust piles behind. If you see these piles you could have carpenter ants.

All species of ants have winged reproducers which most homeowners mistake for swarmer termites.

 Trustindex verifies that the original source of the review is Google. First time customer - I called Mike Brennan after being referred by my family member. He answered my call, evaluated the situation, gave me some incredibly helpful tips to address the immediate issue, and fit me in after his last appointment on the same day. Mike and his associate (also Mike) arrived when they estimated, inspected the problem area, got to work, eliminated the problem and sealed the area all within an hour. The job was foul and they got pretty dirty, but they maintained their professionalism throughout. It’s doubtful you’ll find a more professional team in the area. Though I hope I will not need this particular service ever again, I would not hesitate to call them should the need arise. Thank you Mike and Mike!

 Trustindex verifies that the original source of the review is Google. Excellent service from start to finish. He was professional, punctual, honest, and extremely knowledgeable about termite treatment. From the initial inspection, he took the time to explain everything in detail with great patience, helping us understand exactly what was happening in our home, where the termites were likely coming from, and the best way to treat the problem. Thanks to his expertise, he correctly identified the source and created a detailed, effective treatment plan focused on the affected areas and around the home. He and his team completed the work efficiently and respectfully. It’s rare to find someone so trustworthy, dedicated, and clearly passionate about what they do. I highly recommend their service.

 Trustindex verifies that the original source of the review is Google. Mike is awesome! Really such an absolute pleasure to deal with. Randomly found him searching online (was looking for a truly family owner and operated business) and he didnt disappoint. We had an earwig infestation. I called Mike and he is probably one of the most patient human beings I have met. He spent time discussing the issue and the treatment. There was absolutely no pressure to use him. We ended up using him and he came and again explained everything he was doing.. he was extremely thorough and it's a month and half later and we are still bug free.
