Both Ditrac Blox and the Contrac Blox are anticoagulants but Ditrac is a multi-feed rodenticide (rodents would have to feed multiple times to build up a lethal dose) and Contrac is a single feed rodenticide (rodents usually obtain a lethal dose in just one feeding). Unfortunately, there is no way to know if chipmunks would be attracted to either of the baits. When dealing with mice the size of the bait stations is up to you.  If you would feel more comfortable with a station with smaller entry holes, the Protecta Mouse Bait Station would be a great choice. These stations are tamper resistant, lock with a key and are very sturdy.

It is possible that the rats are not attracted to the Ditrac All Weather Blox because there is another food source available to them. We would recommend removing any type of food items (pet food possibly) and/or moving trash to another area. We would also recommend inspecting your home for areas that they can get in through. Check all doors, door frames, windows and window frames. Replace any weather stripping that does not create a tight seal. Replace any broken window panes. Replace any damaged window or door screens. Repair any gap, hole or crack around frames that are ¼” or larger. If gnawing damage is present on doors, a metal kickplate should be installed to prevent any additional gnawing.Inspect all trees and hedges near home. Any tree branches or hedges that touch or hang over the house should be cut back to prevent rodent from using them as pathways onto and into the house. Keep grass short and trim bottom of hedges or bushes to expose soil beneath and eliminate rodent harborage areas.Inspect the roof. Check shingles, roof ventilators and vent screens to be sure they are secure and undamaged, replacing or repairing as needed. Make sure the chimney is capped to prevent animal entry.Remove food and water sources when possible. Feed pets in the morning and remove any uneaten food immediately. Find and fix any leaking pipes or drains. Remove bird feeders if possible to eliminate the bird seed as a possible food source. Clean up any rodent feces and urine found during the inspection. Be sure to wear protective gloves and a respirator to avoid breathing in any fecal matter. Use a bleach solution to clean rodent nesting areas and entry points to get rid of any pheromones left behind that may attract future rodents.   Please let us know if you have any additional questions.

Ditrac actually is available for sale to New York.  We fixed this error on our website saying it was not available.  Ditrac is the slower acting of the the two (Ditrac & Contrac).  Contrac blox are by far the most popular and what we sell the most of.  They work great and rarely do not work.
