This program serves as a resource for accurate, unbiased information on pest management and on the prevention and education of tick-borne illnesses.

Larry is on the silver screen! Directed and produced by Marnie Crawford Samuelson and Shane Hofeldt, Tick Days features county entomologis Larry Dapsis – part tick detective, part evangelist — as he tries to protect Cape Codders and visitors from being infected by tick-borne diseases.

Protect Yourself- Repellents
The use of repellents can be a highly effective way to prevent tick bites and reduce the risk of getting any number of tick-borne diseases including Lyme, babesiosis and anaplasmosis. Although there are many products on the market, Permethrin is the only product that provides effective, long-lasting protection.
Permethrin is to be applied to clothing, including footwear, NOT skin. Highly effective at repelling/killing ticks. Effectiveness lasts through multiple washings. Pre-treated clothing is also on the market. This is a good complement to skin-applied repellents. EPA’s position is that treated clothing poses no immediate or long-term effects to toddlers, children, pregnant women or nursing mothers. Check out this short How-To video on applying Permethrin:
There are a number of permethrin products designed for different applications. Consumer should be careful to select product specially formulated for application to outerwear/camping gear.
Apply permethrin to your footwear every four weeks. This is very important during the summer months. Nymph stage deer ticks, the size of a poppy seed, are down in the leaf litter…the first place they attach to are your shoes. This is a great FIRST line tactic…Nymph stage ticks are responsible for 85% of all tick-borne diseases in Massachusetts.
Visit Insect Shield for insect repellant clothing and gear.
Where to Buy
Protect Your Yard
Perimeter Yard Sprays
In addition to permethrin-treated clothing/footwear a perimeter yard spray creates a good 1-2 punch program. Deer ticks are not found out in the open lawn…short grass, direct sunlight is a hostile environment for ticks. At the edge of the yard where the grass might be in partial shade and transitions to brush, trees, leaf litter this is perfect tick habitat and is the area you want to treat. This includes beneath woody ornamental plantings.
There are companies on the Cape that perform this as a service. The product that they should be using is Talstar (active ingredient bifenthrin). There are “all natural” products that are available but there are no research data to support that they are effective. Besides being highly active against ticks bifenthrin is immobilized when it contacts leaves or soil particles so it will not wash off site or leach through the soil. Product should not be applied around surface waters.
Applications are recommended for mid to late May and mid to late June when nymph stage ticks are active. A fall spray in mid-October can be considered as this is when adult stage ticks emerge.
Homeowners can also do this themselves. Garden centers carry a product under the Bonide brand. Eight is a hose-end sprayer that contains the active ingredient permethrin.
This product was designed to kill ticks on mice. It consists of a cardboard tube which contain cotton balls treated with permethrin. The product concept is that mice will remove the cotton balls and line their nest and self treat.
There were two studies done on this product. Both studies demonstrated that the product had NO material impact on tick populations. The papers can be found in the Research section of this website. It is a product that Larry Dapsis does not recommend.
Lyme Disease is the most prevalent infectious disease in Massachusetts and is now considered to be a public health crisis. In addition to Lyme, deer ticks can carry the pathogens which cause Babesiosis, Anaplasmosis, Relapsing Fever and Powassan virus, all of which can be very serious and are on the increase.
This program will review the basic life cycle and ecology of deer ticks, incidence rates and distribution of tick-borne illnesses in addition to a database under development on infection rates of ticks. A three point protection plan will be presented: Protect Yourself, Protect Your Yard and Protect your Pet. Tick-Borne Diseases are preventable.
