Southern Rhode Island suffers from an endemic deer tick population that is growing daily. We all know that ticks pose a serious threat to our health. To make things worse, the fear of ticks has forced thousands to change their lifestyle and the way they use their yards. In 2008, Kaiser Tree created a subsidiary named Ocean State Tick Control, to focus solely on tick and mosquito abatement. We created a reasonably priced program that will completely eliminate ticks from your landscape, allowing you to feel comfortable in your own backyard again! Our practice is environmentally safe and the most effective available.

What are ticks?

Ticks are not insects at all, but small Arachnids, similar by nature to mites, spiders, and scorpions.

In the northeast, there are 2 common types of ticks: Deer Ticks (potentially very harmful), American Dog Ticks (generally benign, but in rare cases, can transmit Rocky Mountain Spotted Fever).

How do ticks feed?

  • Ticks are parasites
  • Ticks feed by latching onto a human or animal “host”, embedding their mouthparts into their host’s skin, and then sucking the host’s blood until they are engorged.
  • Ticks’ feeding method makes ticks perfect vectors for transmitting diseases.

Deer Tick Life Cycle

Tick Life Cycle

The most common transmitters of Lyme Disease in the northeastern U.S., deer ticks (black legged ticks) are hard-bodied with two year life cycles that consist of three stages:

STAGE-I: Larval — Larvae hatch from eggs in summer and actively seek their first blood meal in late summer. No larger than a newsprint period, larvae are nearly impossible to detect. They contract Lyme only by feeding on infected, small mammal hosts such as the common white footed mouse, chipmunks, squirrels, etc.

STAGE-II: Nymph — After feeding, larvae drop off hosts, burrow into the leaf litter, and molt into nymphs (second stage) in the fall. The resultant nymphs remain inactive through the fall, winter, and early spring. These nymphs emerge from the leaf litter starting in late May, and continue actively seeking a bloodmeal through July. Their preferred hosts are again small mammals, but they often will latch onto dogs and humans as well. In New England, about 25% of nymphs carry Lyme Disease. Nymphs are considered the most dangerous stage of the tick life cycle because they are so small (size of a poppy seed), and quite often will latch onto a host without being notice.

STAGE-III: Adult — Nymphs fall off their hosts into the leaf litter in the early summer and molt into adults. These adult ticks “emerge” into activity in early October. They aggressively seek new hosts through fall, waiting generally, for large mammals including humans, dogs, cats, horses, and deer. Most active in October, November and early spring, 50% of adults have been found to carry Lyme Disease in New England. When temperatures dip below 40 degrees F. Ticks usually drop into leaf debris and become inactive; but as soon as temperatures rise, they resume their quest for hosts – usually in late February or early March. By late March/early April, they are ravenous for a new blood meals, which they need to successfully mate and reproduce. Females drop off their hosts to lay about 3,000 eggs in the leaf layer and then die. In late summer, these eggs hatch, beginning the tick life cycle anew.

What to do when you get bitten by a tick?

The most common reaction to being bitten by a tick is to frantically pull/ dig the tick out of the skin of the person or pet that it has latched onto, then flush or destroy the tick. Taking the right steps while removing a tick can make a big difference in the effect that tick bite has.

  • First, a pair of tweezers should be used to pinch the tick up around its mouthparts, not in the back of the tick. This helps get the tick out in one shot, and by not squeezing the back (abdomen) of the tick, you aren’t forcing the blood/ bacteria from the tick back into the victim.
  • Second, the tick should be placed in a plastic baggie which is rolled up and secured shut. After determining how long the tick was latched on for, you may choose to have the tick sent to a lab and tested for Lyme Disease or other tick borne illnesses. Remember, all ticks are not infected, and therefore, all tick bites will not get you sick. By having the tick tested, you can know for sure whether the tick has the potential to get the victim sick.
  • The tick bite should be treated with antiseptic and the victim should be watched for a bull’s eye rash, and/or other common symptoms of an acute case of a tick borne illness.

Tick-borne Diseases

Ticks latch onto humans and animals, embed their mouthparts into their hosts’ skin, and suck their blood. This makes these parasites perfect vectors for spreading disease.

In the United States ticks spread numerous diseases in humans including:
Lyme Disease, Babesiosis, Ehrlichiosis, Rocky Mountain Spotted Fever, Anaplasmosis, Ehrlichiosis/Human /Granulocytic Ehrlichia (HGE).


  • Lyme: Bulls-eye rash, fever/chills/joint pain, fatigue, swollen joints/lymph nodes, heart palpitation, sleep disruption, neuropathy, Bell’s Palsy. Can be fatal
  • Babesiosis: Headache, fever, fatigue, weakness, appetite loss, muscle pain, sweats, confusion; If untreated, up to 5% die
  • HGE: Rash is uncommon, fever/chills/shaking, muscle/joint pain, headache, malaise, nausea, vomiting, weight loss, confusion. Can be fatal
  • Rocky Mountain Spotted Fever: Spotty rash 5-10 days after infection. Fatal in 10% of cases

Ticks and Tick Bite Photos

While smaller than the dog tick, adult deer ticks are the largest stage of the deer tick life cycle. They can be seen fairly easily on the skin, but are very hard to find on dark colored clothing.
Nymph Deer Tick

Nymph deer tick

Nymph (second stage) ticks are tiny, and quite often go unnoticed when doing tick checks. Roughly 20% of nymph Deer ticks carry Lyme disease.

Bulls Eye Rash

Bull’s eye rash

Even though it does not always appear, a “bulls-eye” rash is a sure sign you have been bitten and infected by a deer tick. See a doctor immediately. This child was bitten on the back of the thigh.

The Kaiser Family Tick Story

My name is Ames Kaiser, owner of Ocean Sate Tick Control.

In 2004 I contracted Lyme Disease for the third time in my life. I also pulled deer ticks off my wife, children, and our dog. Clearly, something had to be done to make our home safe. We live on an acre of landscaped property, with woods on three sides. Deer, squirrels, chipmunks, etc. are in our yard daily. I researched tick control and found URI tick specialist Dr. Thomas Mather’s publications very informative on They became the foundation of our home tick control program.

First, I cleared the perimeter of our yard of brushy growth, and kept the grass cut low. Then, using my tree sprayer, I applied the recommended material (permithryn) around the perimeter of our yard and on our planting beds. The results were instant: I stopped seeing ticks on my family and our dog. (An invisible fence keeps her in the yard. She now gets no ticks at all, but, because we cannot stop our cats from wandering, they still get ticks from time to time.) Because I am a “tree guy”, I’ll always find ticks on myself, but my family is now well protected!

When I saw these results, I created Ocean State Tick Control to offer similar protection to other families. Broadening our focus to controlling ticks in residential landscapes was a natural progression since Kaiser Tree already had been a leader in tree pest control for decades. Since founding Ocean State Tick Control in 2008, we have developed a sophisticated and effective program which is reasonably priced and environmentally safe. We now treat countless homes in RI, eastern CT and nearby towns of Massachusetts, and have yet to have a single family report that the program wasn’t working.

We contacted Kaiser Tree Preservation Co. in April 2013 to have our yard's perimeter treated for ticks after four members of our family contracted Lyme Disease during the summer of 2012.  Kaiser Tree is an excellent company across the board--punctual, professional, and competent in every service they offer. After being impressed with their tree service (both removal and planting), we decided to use them for tick spraying.  We noticed immediate improvement in tick activity in our immediate yard. They spray the perimeter of our yard very thoroughly 4 times through the active tick season and always call a day or so ahead prior to their actual spraying.  We will continue to use this company for our tree and yard services, and most definitely, future tick and mosquito control. We give our highest recommendation and feel fortunate to be able to rely on their expertise.

They are very good about calling ahead and we've seen far fewer ticks so far this year than last...fall is worst so time will tell.  Happy so far because, after such a wet winter was expecting tick increase.  What's extra great about this company is that a professional, knowledgeable person answers the phone or calls back immediately.  With all the businesses I deal with, this is a rare delight.  I've also used this company for ailing trees and bushes. Results are positive there also.

Excellent service. Got right back to me if voicemail picked up when I called.  Scheduled all three application appointments at once. Haven't seen any ticks at all!
