There are also more natural alternatives available, with varying degrees of efficacy against different tick species, different life stages, and for various lengths of time. DEET-based repellents also last 2-3 times as long as natural repellents. Nonetheless, if you are in tick country and will only be applying the repellent occasionally, even these choices may be better than the risk of contracting a tick-borne disease.
The two most effective tick repellents are DEET and permethrin, both of which have questionable safety profiles. If ingestion is a concern, spray in areas the dog cannot reach as easily, such as the back of the neck, the base of the tail, and the chest between the front legs. Lightly spraying the dog’s legs, belly, and back with a dog-safe repellent may be more effective. The same goes for dogs-only applying a repellent blend to the dog’s collar may encourage the tick to find another, more suitable attachment site somewhere else on the dog’s body.

You should apply chemical repellents directly to the skin as well as clothing since repellents on clothing alone may encourage the ticks to move under the clothing onto your skin. Long-sleeved shirts and long pants protect your skin, while light colors make it easier to see hitchhiking ticks crawling around, looking for a place to settle down for a meal. The best physical precaution to repel ticks is to wear light-colored, tight clothing that covers exposed skin. There are both physical and chemical means of preventing tick bites when trekking through tick country, and a combination of the two is often the best approach. Tick-borne diseases can be challenging to diagnose and are sometimes deadly hence, avoiding tick bites is the best way to prevent contracting these diseases. Tick-borne disease cases are also on the rise, so diligence to repel ticks is increasingly necessary (Chrobak, 2022). These parasitic relatives of mites are vectors for numerous human diseases, the most widely recognized being Lyme disease and Rocky Mountain spotted fever (Centers for Disease Control, 2022).

In addition, nootka oil could be beneficial in situations where ant suppression rather than complete quarantine elimination is the management goal.Īlaskan yellow cedar Solenopsis invicta Solenopsis richteri hybrid imported fire ant nursery production.
Although the formulation tested here did not perform to Federal Imported Fire Ant Quarantine standards, other formulations may enable this product to reach 100% control. The quarantine-approved bifenthrin band treatment maintained 100% control from the 2nd to 24th wk. In a band application evaluation, nootka oil plots maintained a 90-95% reduction in fire ant mounds from the 2nd to 17th wk, when new mounds began to intrude on the field plots. In a field drench test, mortality of mounds treated with nootka oil lagged behind mounds treated with bifenthrin treatment for 7 wk, but both nootka oil and bifenthrin had higher mortality than the untreated check at the end of the 12-wk evaluation period. Higher worker mortality was also observed in contact and fumigation assays compared to control checks. In digging assays, ants were repelled by nootka oil and digging continued to be suppressed by nearly 50% in nootka oil-treated sand aged 6 mo in the laboratory. Don) Spach, has activity against hybrid imported fire ant workers, Solenopsis invicta Buren × Solenopsis richteri Forel. In this study, we demonstrate that the essential oil of the Alaskan yellow cedar, Cupressus nootkatensis (D. This demand has led to increasing focus on plant essential oils as sources of new biopesticides. Recent concerns regarding the impact of traditional synthetic pesticides on nontarget organisms have generated demand for alternative products with lower environmental impact.
