Cockroach Extermination on Long Island

Signs You Have Cockroaches in Your Long Island Home

You have cockroaches in your Long Island home if you see live roaches in daylight, pepper-like droppings inside cabinets, egg cases stuck near hinges, or a musty odor in the kitchen. In Nassau County apartments and older Levittown-era kitchens, German cockroaches cluster near warm motors: under the fridge, behind the dishwasher, inside the toaster oven. In Suffolk County, larger American and Oriental roaches often push in from crawl spaces and basements after heavy rain. Any daytime sighting suggests a population well past the earliest stage, since roaches are nocturnal and only leave shelter in daylight when the harborage is overcrowded. Sticky monitors placed for 48 hours will confirm species and hotspots before treatment.

How Bobby Bugs Treats Cockroaches

Bobby Bugs treats roaches on Long Island with a targeted gel bait and insect growth regulator program that reaches the colony inside walls and appliances, not just the roaches you can see. Expect a thorough kitchen and bath inspection, targeted treatment in cracks and voids, and a follow-up plan inside the 60-day guarantee window.

  1. 1Free phone triage: we ask what you are seeing and where, and confirm species and pricing.
  2. 2On-site inspection with sticky monitors in the kitchen, bathroom, and any suspect appliances.
  3. 3Targeted gel bait plus insect growth regulator applied to cracks, voids, hinges, and motor bays.
  4. 4Sealing of obvious harborage points such as gaps behind kick plates and around pipe penetrations.
  5. 5A written 60-day guarantee, plus a scheduled follow-up if the population was heavy.

How Long Does It Take to Get Rid of Cockroaches?

Most Long Island roach jobs are functionally resolved in 7 to 14 days, with visible activity dropping sharply inside the first 72 hours. German cockroach populations are knocked out in one to two visits in the majority of cases, while heavier apartment building infestations sometimes need a follow-up between weeks two and four. American and Oriental roach problems, which are more about moisture and entry points, often clear in a single visit plus fixing entry points. The 60-day guarantee covers any bounce-back inside that window.

How to Keep Cockroaches From Coming Back

To keep German cockroaches from coming back, take away food, water and hiding places at the same time, because University of Florida entomologists describe those three as the survival triangle that has to be broken together. Get rid of cardboard: German cockroaches thrive in it, so move long-term storage into plastic bins and break down delivery boxes the day they arrive. Fix leaking pipes and drains, wipe condensation under the sink, and don't leave dishes or pet food out overnight. Store food in sealed containers and clear clutter from cabinets, under the stove and behind the refrigerator. German cockroaches don't come in from outside; they're carried in on boxes, bags, used appliances and furniture, and in apartment buildings they move between units through shared walls and plumbing, which is why a single unit sprayed and left alone gets reinfested. Surface sprays miss the first-stage nymphs hiding in wall voids, which is why our treatment is built on gel baits and growth regulators that reach the whole population.

How Much Does a Cockroach Exterminator Cost on Long Island?

Cockroach extermination cost on Long Island depends on the species, how established the infestation is, and the size of the space. A single German roach sighting in a Hicksville apartment kitchen is a very different job from American roaches throughout a Babylon basement. Apartment treatments are usually quicker; whole-house jobs with heavy harborage need more material and more time. Most cockroach jobs include a follow-up visit two to three weeks later to catch newly hatched nymphs, and that visit is part of the quote. Bobby Bugs gives you a free written quote before any work begins, and the number on the invoice matches the quote. Every cockroach extermination job includes the 60-day written guarantee.

What customers say

So let’s start with this.I was out of town, and my daughter called me in a frenzy that she saw a roach. 10 years in that house never had roaches. Here I am out of state trying to figure out the fastest way to help my daughter. Saw the name BOBBY BUGS and the reviews and figured I would call them up.I called spoke to Anthony not only did he go above and beyond for us but the service was fantastic. William who showed up at the house was simply incredible and made my daughter feel at ease. Thank you for helping our little Italian Family out in such a pinch. Grazie Mille Adriana

Fast, friendly service. I called in the morning and Will came to my house that evening. Will was great. I would definitely use Bobby's Bugs again and recommend them.

Response was super quick to my inquiry and someone was able to be sent out out quickly. Will came and explained the process, walked me through and showed me what he had done, and reviewed the service order to make sure none of my requests were missed. It was a great experience overall and truck wasn't announcing itself to the neighborhood either which was a plus.

Frequently asked questions

Why do I have roaches in a clean house?

Roaches ride into clean Long Island homes on grocery bags, cardboard, used appliances, and pipes shared with neighbors. German cockroaches only need water and warmth, so a clean kitchen with a slow drip under the sink is plenty. Cleanliness helps prevention but does not stop the initial infestation.

How long after treatment do roaches die?

You will see dying and disoriented roaches within 24 to 72 hours after a Bobby Bugs treatment, with the bulk of a German cockroach population knocked out in 7 to 14 days. Gel bait works through the colony, so you should not spray over it. Full cleanup typically completes inside the 60-day guarantee window.

Do German cockroaches go away on their own?

No. German cockroaches do not leave a Long Island apartment or house on their own. A single female can produce hundreds of offspring in months, so the population grows until it is treated. Professional gel bait, insect growth regulator, and crack-and-crevice work is what actually ends the infestation.

Is one roach a sign of infestation?

One German cockroach in daylight usually means many more hidden nearby, since German roaches are highly social and stay clustered. One American or Oriental roach may be a single hitchhiker from the basement or a pipe. Either way, an inspection is free and takes the guesswork out.

Do I have to leave the house during a roach treatment?

For a standard German cockroach treatment, no. Our treatment is built on gel baits and growth regulators placed in cracks, voids and behind appliances, not a fog, so you can stay home. We ask you to keep kids and pets out of the kitchen while we work and until the placements are done, and we tell you before we start if a particular job needs anything more than that.

Why does my neighbor's roach problem keep becoming mine?

Because German cockroaches travel through shared walls, pipe chases and hallway trash rooms, and a female carries an egg case with 30 to 40 eggs. If one unit in an attached building is untreated, it reseeds the others. We treat your unit and the adjoining voids, and we'll tell you plainly if the building needs to be treated as a whole.

Are the big roaches in my basement the same as the ones in my kitchen?

Usually not. Big reddish roaches an inch or more long coming up from a floor drain or under the basement door are American cockroaches, which live in sewers and damp ground and are common on the low-lying South Shore blocks. Small tan roaches in the kitchen are German cockroaches. They're treated differently, and we identify which one you have before we quote.

Own a restaurant or manage a building?

Businesses and multifamily buildings need a recurring program, not a one-time visit. See how we handle restaurant pest control and pest control for apartment buildings.
